Cabinet Compartments The RTC-4350 is divided into front and rear equipment compartments, splice bay, and battery base compartments.

Equipment Compartment

The Equipment bay houses the DC power subsystem, the Occam 6012 BLCs, alarm panel, breaker panel, and room for future expansion. Future expansion can include splice and termination fiber management, pre-terminated fiber management and/or specials equipment. There is 8RU of expansion space in the front bay below the 6012 chassis and 10RU of expansion in the rear bay. Located at the top of each equipment chamber is the internal equipment air circulation system. This environmentally controlled cooling system draws air up through the electronics and pushes down through the baffles on the door mounted heat exchangers. Located below the fan assembly is the Valere DC distribution shelf. The unit supports up to four 30Amp rectifiers. Three (3) are shipped with the base cabinet configuration. The Valere unit is configured with a BC1000 intelligent Ethernet controller. The Valere controller is Ethernet connected to the BLC chassis.

Rectifier System

The RTC-4350 comes with a Modular Valere power supply system. The power supply accepts an AC Voltage between 90 and 264 VAC, 47 to 63 Hz, and produces a regulated 54 V DC output in an ambient operating temperature range of -40°C to +75°C.This power system is up to 92% efficient. The cabinet is shipped with three 30 AMP rectifiers, however the power system supports connection for up to four rectifiers. The Valere Rectifier shelf supports the installation of an intelligent Ethernet enabled controller.

Heat Exchanger

The RTC-4350 is equipped with two door mounted heat exchanger units. The heat exchangers may be equipped with a thermally activated variable speed fan controller. This controller reduces fan noise and energy consumption during less demanding thermal periods. An additional noise cancelling baffle option may be configured at the factory to reduce noise further. These measures significantly reduce the fan noise below 65dB to an estimated performance of 55dB. The RTC-4350 is equipped with a dual loop cooling system. The outer loop vents through the battery base as described previously. The inner loop stirs the air within the equipment chamber. Both the inner and outer loop fans are thermally activated and do not exchange air.




Fuse and Alarm Interface Panel (FAIP)

The FAIP is located in the electronics compartment. It is equipped with plug-in, alarm-indicating fuses for distribution of -48V DC power to the cabinet fans and control circuitry on the FAIP. The fused circuits are used to power other cabinet equipment. The Valere rectifiers, batteries, and load fuses are connected to a common bus, such that the batteries start supplying load current when the bus voltage drops below the open circuit battery voltage. No switching is required.

Fiber management

The cabinet may be equipped with either pre-terminated fiber patch panels or in-cabinet patch and splicing. There are multiple benefits to each practice. Occam provides both solutions to meet the needs of either fiber distribution connection practices. When using a pre-terminated fiber patch panel the splicing to the subscriber distribution is done outside the cabinet in either a hand hole, splice pedestal, or splice case. The standard length of the fiber panel tail is 100’ non-armored loose tube cable. Pre-terminated fiber patch panels are available in 144 (PN 650337) and 288 (PN 650324) SC/UPC fiber densities. Contact your Occam representative for additional details. These fiber patch panels mount onto the 23” Rail beneath the 6012 chassis within the equipment bay. In the front of the cabinet there is 8RU of available rack space. In the rear bay there is 10RU of available rack space. With these optional field installable panels a copper installation




can migrate to fiber easily. Pre-terminated panels may be added to the configuration at any time. Once installed the fiber blades can be wired to the distribution panel.

Alternatively, for an all fiber installation PN 670305 changes the splice bay to include two 23RU 19 inch rails. With in this bay up to twelve 144 position fiber management panels can be added for high density installations PN 650416.

Separately ordered fiber jumpers (PN 315134) are required to connect

the fiber patch panel to the Occam BLC. For Equipment bay fiber bulkhead installations, Occam recommends 2M jumper for interior blades

slot, 2-11 and 1M jumpers for the bookend positions. These fiber jumpers

are dressed left slots 1-6 and right slots 7-12 appropriately. Occam

recommends non-armored OSP tails to the external splice point. The

pre-terminated fiber management solution, may be mounted either in the

splice bay (PN 670305) or directly beneath the equipment (PN 670302,670303) located in the front of the equipment bay directly

beneath the Occam BLC. Jumper lengths of 5M are recommended for

the 670305 solution. The 144 fiber pre-terminated management panel

(PN 650337) and Splice/Termination (PN 650290) are shown below.

When using a splice and patch panel solution one (1) non-armored OSP distribution fiber cable is brought into the splice shelf. PN 650290 is designed to support up to 120 fiber subscribers. An optional 60 fiber subscriber panel may be added to support a total of 180 subscribers using a splice / termination solution. The 120 Fiber Management Solution is integrated into the cabinet and consists of a 2RU fiber Splice tray with capacity for 120 fibers, two (2) 2RU 60 fiber SC Patch trays, and an 8RU fiber slack management system. Fiber pigtails (PN 314133) to connect the splice tray to the patch tray and fiber jumpers (PN 315134) to connect the patch tray to the Occam BLC are required. A fiber management panel with splice tray and an optional third patch tray is shown below.







Splice Bay

The splice bay is located on the side or the cabinet. The splice bay as shown in the diagram above may be configured for copper or fiber deployments. The Copper configuration fills the splice bay with twelve (12) 100 pair block protection panels. The Fiber configuration fills the splice bay with two (2) 23RU 19” rails to mount fiber bulk head panels. The Fiber configuration allows the installation for up to three (3) 100 pair block protection panels. Both configurations include the transport fiber, convenience outlet, and main cabinet ground.

Protection panels

The 100 pair protection panels are wired CAT5 to an RJ-21 connector to attach to the back of the Occam BLC chassis. A wiring diagram is displayed in the cabinet. The 100 Pair block is wired CAT5 to the splice connector. These connectors are located in the splice area adjacent to the protection blocks. Each 100 pair protection block is dead pair wired (pairs 49, 50, 99, and 100) and is connected to the rear of the Occam Chassis.

Fiber Configuration (PN 670305) - The Splice Bay has two 23RU 19” rails for mounting modular 144

position pre-terminated LC bulk head panels. - The Splice Chamber supports up to twelve panels for a maximum

subscriber distribution out count of 1728. Note: The 18RU of space in the equipment bay remains available for equipment expansion.

- The field installed fiber management panel is mounted onto the rail and the fiber tail is then fed blunt end down the conduit to the splice location

- Variable OSP tail length: 100’, 250’, 350’, - Craft separation from electronics bay







AC Power Distribution Panel

The AC power distribution panel is located outside the cabinet and includes an integrated TVSS surge suppressor. The maximum AC Panel input is 60A 240vAC. The maximum generator input is 30A 240vAC. The back up generator connector is located on the bottom of the AC power panel. The AC Panel is UL Listed under "Enclosed Industrial Control Panel" No. BM-601768. The vendor is Schnieder and the catalog # is 8930COM7263G3. Note: The -48vDC Rectifier shelf supplying the electronic equipment is capable of distributing a maximum of 6000w using the four (4) 30A (1500w) -48vDC rectifiers. As described previously three 30A rectifiers are shipped with the cabinet to provide redundant power to the Occam BLC 6012 Chassis.

The RTC-4350 is also equipped with a power meter housing. Integrating the power meter eliminates an additional pedestal as the remote site.

External Generator Wiring

The RTC-4350 comes equipped with an external 30A Hubbell generator connector. The weather sealed generator connector features a screw tight connector to seal the plug.

Transport Fiber

The RTC 4350 includes a transport fiber management panel with in splice

bay of the cabinet. The transport panel supports in-cabinet splicing of the transport fibers that are then connected to a pigtail to connect to the

Occam BLC.




Battery Compartment

The battery compartment is located directly below the equipment compartment and supports up to four battery strings for backup power. Optional thermostatically-controlled, AC-powered battery heaters protect the batteries from reduced capacity due to cold temperatures, and two (2) battery temperature probes for monitoring battery temperature.

Battery Heaters

The optional battery heaters are located beneath the plate on which the batteries rest. They are designed to prevent the loss of battery reserve capacity that occurs when batteries are exposed to cold temperatures. The heater is connected to a thermostat that is set to operate the heater pad when it senses battery temperatures below 32°F ±5°F (0°C ±3°C) and shut them off when it senses above 50°C ±5°F (10°C ±3°C). When the battery heater and an optional earthquake kit are not provided with the cabinet, the plate is omitted.

Battery venting is provided by the heat exchangers within the base cabinet configuration. The heat exchangers draw air through vents into a baffle located at the top of the splice bay and exhaust the air into the heat exchanger plenum. Outside air, drawn past the batteries by the heat exchanger, reduces the heating of the batteries that otherwise occurs as a result of solar heating of the battery compartment sides, radiant equipment heat from the equipment bay, and self-heating due to charging. This resulting reduction in battery temperature extends the life of batteries.

Security

The electronics and side compartment doors are accessed using an industry standard hex key; locks can be padlocked, if required. The battery panel and cable entrance panel can only be removed by first opening the electronics compartment door and side compartment doors, respectively.




Chapter 2

Site Planning In this Chapter

This chapter describes the planning and prerequisites needed to install the RTC- 4350.

The following precautions must be observed when installing the RTC4350 cabinet. This is not an exhaustive list. Consult local safe practice guidelines, company installation guidelines, and follow all local building and electrical safety codes.

• Whenever possible, a cabinet should be located in vacant, unused, and out-of-sight portions of private, public, or commercial property with easy access and adequate parking. If a cabinet must be located near a street or highway, it should be located away from curves and busy intersections.

• Consult company safe practice guidelines for cabinet site locations.

• Consult company guidelines for cabinet placements regarding rights-of-way and location. Cabinets should be located in an area that is not prone to flooding, next to in-ground sprinkler systems, or constantly damp soil. The cabinet is not intended to be submerged or partially submerged by water, mud, or debris. Local zoning practices and restrictions should be followed prior to pad installation and cabinet placement.

• Restrictions: The following installation locations should be avoided:

o Small alcoves that enclose the cabinet on 3-4 sides o Small alcoves that receive direct sun in the mid to

late afternoon o Hot air exhaust from neighboring buildings or

structures o Hot surfaces such as dark asphalt, tarred roofs,

crushed rock Small alcoves, hot air exhaust, and hot surfaces may cause high-temperature alarms and shutdowns. Small spaces or certain surfaces that receive direct sun light tend to retain the solar energy resulting in a much hotter




microclimate installation location. Heat gain within the cabinet has many dependencies such as site loading and traffic, solar thermal loading, geographical location, time of day, weather, cabinet orientation, shading, surroundings, and external air movement. Plan the site to meet or exceed the requirements of local architectural codes, bylaws, or environmental restrictions as applicable.

Safety

Follow all safety guidelines when using pre-cast concrete foundation pads. Pre-cast pads should be in place prior to setting the cabinet. Attempting to place a pre-cast pad over existing cables can result in an unsafe work condition if a person reaches under the pad as the pad is lowered to feed cables through the opening in the pad.

• Only operators who are specifically trained and who meet company requirements shall be permitted to operate heavy equipment to place a cabinet.

• All persons working with heavy equipment shall wear standard safety headgear, eye protection, and when required, insulated gloves.

• Follow all safe operating practices when using heavy equipment.

• Keep bystanders away from all work operations.

• Operators shall not suspend loads over people; nor shall any person be permitted to work, stand, or pass under a suspended load.

Pad-Mounting Bracket Kit

The construction of the concrete foundation pad on-site requires the use of a foundation pad mounting bracket kit PN# 535125. However, precast foundation pads, manufactured by concrete fabricators, do not require the mounting bracket kit.

When required, the mounting bracket kit may be ordered with the cabinet or separately. The pad-mounting bracket kit must be ordered in advance of pad construction and cabinet placement. Note that the pad requires several days to cure prior to cabinet placement.

The pad-mounting bracket kit, in the diagram below, is composed of the bracket, anchors, cabinet mounting screws and washers, and two duct alignment plates. The bracket and inserts become a permanent part of the concrete pad. The duct alignment plates are used to provide the proper location for the cables and ducts, and are discarded after the pad is fabricated. The screws hold the anchors and duct alignment plates in place while the pad is being constructed. The screws are discarded prior




to placing the cabinet on the pad. A new set of screws, shipped with the cabinet, are used to secure the cabinet to the pad.

The pad-mounting bracket kit provides:

A level mounting surface for the cabinet

The exact location of the anchors for fastening the cabinet to the pad

The proper location of the OSP cable and AC conduit openings

Pad Sizing

The RTC 4350 cabinet pad drawing provides design information for two cabinet foundation pads: the standard pad and the small-footprint pad. The standard pad, which measures 100 inches (2540mm) by 100 inches (2540 mm), provides walk-around area on all sides for installation, turn-up, and maintenance activities. Also, because the standard pad is a thin slab design, it is the easiest pad version to fabricate. However, if there is insufficient space for the standard pad, the smallest footprint pad that

45.9 inches

51.4 inches




allows the cabinet to be installed in an area as small as 60 inches (1700 mm) by 48 inches (1400 mm) by 6 inches (mm) thick. Both pad versions can be precast and easily transported to the installation site on a standard flatbed truck without the need to stand it up on edge.

Site Grounding Requirements

The cabinet grounding system has been designed to protect personnel from shock hazards, to protect the equipment from lightning transients and other electronic noise conducted into the cabinet, and to reduce electronic noise emissions to the environment.

The cabinet structure serves as a continuous ground bus, providing multiple points for grounding of internal wiring and hardware. The equipment rack uprights are the primary equipment grounding members of the cabinet structure.

Special attention must be given to the following site grounding details in order to minimize lightning induced equipment damage in areas of high lightning activity.

Ground Ring Requirements

A ground ring, consisting of a solid No. 2 AWG (35 mm2) bare copper wire, must be buried around the perimeter of the concrete mounting pad. The ground ring must be a minimum of 24 inches (609 mm) below grade and within 2 feet (610 mm) of the pad. The ring ground must be bonded, using either an exothermic weld or a listed compression grounding connector, to two 5/8-inch (16mm) diameter by 8 foot (2.4 M) long ground rods. These ground rods shall be driven on opposite sides of the mounting pad, and covered with a DLC Flush Mount Ground Rod Closure, as specified in 629-101-901BT, for inspection purposes.




Notes: 1. Top of ground rods must be at least 6 inches below grade. 2. Ground rod connections shall be made using exothermic welding (i.e., CAD weld) or using a listed compression clamp. 3. As an option, ducts may be provided for the ground wires. Do not use metallic ducts when multiple cabinets or structures share a common grounding system. 4. Ground system shall comply with national electrical code (NEC) and applicable local requirements. 5. Ground rods and ground ring conductors must be spaced apart by at least 6 feet to maintain grounding effectiveness. The ground rods and ground ring conductors may be installed beneath the foundation pad when required. 6. Ground cables from ground ring shall be routed into pad conduit.




Easement Size

When selecting an installation site, choose a location that has a minimum functional easement large enough to walk around the cabinet with its doors in their fully open and locked position. The Table below shows the area required for the cabinets when the doors are opened to their locked positions. The RTC 4350 cabinet doors extend beyond the minimum pad size as shown below. The following diagram shows the cabinet installed on the foundation pad.

Standard Pad and Minimum Functional Easements

Standard Pad Size Minimal Functional Easement

100 in x 100 inches (2540 mm x 2540 mm)

116 in x 162 inches (2946 mm x 4115 mm)







Chapter 3

Cabinet Installation In this Chapter

Cabinet installation describes the main activities when installing the RTC-4350 cabinet.

Unpacking the cabinet

Remove packaging materials to expose the cabinet as mounted on the shipping pallet. Remove the front and slide kick plates to access battery covers accesses the front and rear bolts. Retain the mounting hardware if needed for future mounting to the concrete pad.




Concrete Pad Installation

Pad Mount Installation Procedure: Step-1 Prepare cabinet-mounting site as follows.

� Dig trench to locate & stabilize bottom entry conduit and ground rod inside conduit entrance holes per the diagram above. (Follow local Telco or NEC requirements for proper system ground rod or ground ring).

� Grade and level pad site to accommodate concrete frame.

Step-2 Assemble concrete forms Step 3 Install gravel base Step-4 Arrange anchor plate inside concrete. Use string lines across form and adjust anchor plate as necessary with gravel to level. Make sure that the top of the anchor plate is flush with the top of the wooden form. Verify that the ½-13 SS bolts are installed into the holes in the anchor plate to prevent concrete from entering the threads. Step-5 Pour concrete level with top of forms keeping the top of the anchor plate exposed and level with the top of the concrete. Allow minimum cure time of 24 hours (Dependent on environmental conditions) before usage. Step-6 Broom finish concrete surface and chamfer all concrete edges.

Conduit and cable routing

The RTC 4350 cabinet was engineered with the following design considerations:

• AC wiring routes into the AC panel through a 3” conduit on the side of the equipment bay. There is a 3” knock out on the bottom of the AC/Meter/GenCon unit. The cabinet has brackets that allow a 3” O.D. conduit to be secured to the exterior of the cabinet.

• Subscriber and transport fiber cable as well as subscriber copper cabling is routed through the conduct access holes on the bottom of the splice bay.

• The main cabinet ground located at the bottom of the splice bay.

Note: Use a non-armored OSP distribution fiber when using a splice / termination fiber management system. Armored OSP fiber is not supported in the cabinet.




Battery installation

Battery installation and maintenance should be done by qualified personnel due to potential exposure to harmful DC voltages and chemicals if batteries are misconnected or damaged. The batteries should always be disconnected (Quick-Connects or breakers) when working on them. In addition, careful attention should be given for proper battery polarity connection. Failure to connect batteries correctly could result in injury to personnel from arcing and damage to the DC rectifiers and any connected equipment that may void its warranty Batteries are extremely heavy. Use extreme caution when handling and installing batteries.

Installation Procedure:

1. Begin this procedure after the cabinet has been securely mounted in place.

2. Ensure the Battery Breakers of the DC Panel are in the OFF

position. 3. At initial installation, remove rectifiers (packaged in boxes) located

in the battery compartment and store in a safe location before populating them in the DC Power Plant.

4. Move the battery cables/temp sensors out of the way during battery install. The batteries should be placed so there is ~ ½" gap between them (there should be 4 to a row).

5. The battery cables come pre-crimped with a lug to connect to the Batt1(-) and Batt4(+) terminals of the battery string. For safety, they have insulating heat-shrink over the metal lugs. For each battery string to be installed ONLY, strip off the insulation covering the metallic lug on the battery cables.

6. Once the lugs are exposed, connect the cable labeled "Str1 +" to the Batt4(+) terminal.

7. Connect the cable labeled "Str1 -" and the Battery Temperature Compensation probe (with ring terminal) to the Batt3(-) terminal.

8. Connect battery cables to batteries (Batt1[-] and Batt4[+] for String 1) before any intercell connectors are installed

9. Connect the intercell connectors (Batt1[+] to Batt2[-], Batt2[+] to Batt3[-], Batt3[+] to Batt4[-]).

10. When all batteries are installed, complete the circuit to the DC Plant (plug in Quick-Connects or turn Battery Breakers ON).




Grounding

The cabinet grounding system consists of a cabinet equipment bay ground and a main ground bar located in the bottom of the splice bay. Please refer to NEC Codes, local building and safety codes, and company grounding guidelines to construct the ground field.

In-Cabinet Fiber Management System

As described in Section 1, the 4350 cabinet has been designed for preterminated fiber management or splice / termination fiber management solutions installed in the equipment bay. The 4350 cabinet may also be configured in an all fiber configuration that locates preterminated fiber management bulk head panels into the splice bay. The following installations proceedures are described for each fiber management solution.

Splice Bay Fiber Installation Procedure:

1) Route the pre-terminated fiber management panel tails through

the bottom of the splice bay. The blunt end of the fiber management tail should be routed out to the splice point. Follow company best practices for slack loop length. Be sure there is a workable amount of OSP cable in the splice bay to allow the installation of the fiber panel. Do not include an OSP slack loop inside the splice bay as this will prevent the installation of all 6 panels per rail.

2) Mount the fiber management panel at the top most position on the rails in the splice bay. The top most installation will allow for easier installation of panels added in the future.

Install top most panels first.

Conduit routing




3) Secure the OSP cable within the splice bay with the fiber bracket supplied with the fiber management panel. The hole pattern within the right rail is intended to attach these cable anchors.

4) After the fiber management panel and the OSP cable have been installed, the panel should open by turning the ¼ turn anchor screw and swing freely without the OSP cable binding. This door swing feature allows for future serviceability capability.

5) For subsequent panel installation the panels mount immediately below the upper panel. Follow the panel and OSP anchor instructions referenced in Steps 1-4. The 2nd panel should be installed immediately under the top most panel. No gap is required.

6) Each Fiber management panel has been out fitted with a pem stud on the top and bottom of the left-rear side of the fiber management panel. This pem stud has been included to allow the panels to be tied together to swing as one panel for servicing. When the ¼ turn anchors screws are in the free position, multiple panels can rotate to the open position for servicing. The panels when tied together should swing freely without the OSP cables causing any binding or tension.

Note: Use caution when opening this fiber management panel as all fibers on the rear of the fiber management panel are 900 microns and can be damaged.

7) After the panel(s) have been installed and tested, remove the record locator panel sticker and place it on the inside door of the splice bay door. When the splice bay door is opened the record locator panel sticker should be lined up to allow for easy to reference record keeping.

8) Fiber color assignments: The panels are numbered in 6 rows of 24 ports each. Buffer tube and fiber number assignments follow industry guidelines and are described in the table below.

9) Fiber panel routing: The panels have been outfitted with right and center guidance pins for fiber management. Jumper fibers may be routed as shown in the diagram below. This fiber routing recommendation allows for the fibers on the right side to be serviced without disturbing the fibers to the left of the affect fiber. Dress the fibers in the panels using Velcro straps.

10) Each fiber panel has been equipped with a Velcro loop on the

right side to secure the jumper fibers exiting the panel. Fiber jumpers exit the panel from left to right through the fiber pins and down. A rubber fiber stop is supplied for the pins on the right side of the panel to prevent the fibers from shifting forward.

11) All fibers jumpers are routed down the splice bay to exit the cabinet. There is fiber guide with a Velcro strap located at the bottom of the splice bay. This fiber guide routes the fibers into the bottom of the equipment bay.

12) Equipment bay fiber routing. The equipment bay has been equipped with slack management along the inside wall of the cabinet and across the rail of the cabinet. Fibers are routed from the bottom of the equipment bay up the side wall and then across the bottom of the horizontal management tray before being routed up to the blade. A photograph of the fiber routing is provided below. Use the split tube provided in the cabinet to guide the fiber from the tie down point at the bottom of the cabinet (5) to the top of the chassis (6). For shorter lengths use the slack loops provided

the same location as the OSP distribution fiber cables. Adequate protection of these BLC-equipment side jumpers via customer provided split tube or spiral wrap is recommended. Individual LC-LC fiber jumpers complete the connection between the equipment and distribution sides of the cross connect.

Equipment Bay Fiber Installation Procedure:

The In-Cabinet Fiber Management System (PN 650290) is installed as follows:

1 Anchor the fiber distribution cable in the cabinet. The diagram below shows quantity two (2) of the In-Cabinet Fiber Management System part number 650290. The contents of the 650290 include the 8RU fiber spools, a Fiber Splice tray and two patch trays. Anchor the OSP cable below the Fiber Management System and route the loose tubes up the left side of the Fiber Slack Management Spools and into the left side of the Fiber Splice trays. This routing is done to reduce the number of turns the distribution fiber needs to make.
