Safety Precautions & Declared Material

General Equipment Precautions

Use of controls, adjustments, or performing procedures other than those specified herein, may result in hazardous radiation exposure.

When working with an Evolution IDU, note the following risk of electric shock and energy hazard: Disconnecting one power supply disconnects only one power supply module. To isolate the unit completely, disconnect all power supplies.

Machine noise information order - 3. GPSGV, the highest sound pressure level amounts to 70 dB (A) or less, in accordance with ISO EN 7779.

Static electricity may cause body harm, as well as harm to electronic components inside the device.

To prevent damage, before touching components inside the device, all electrostatic must be discharged from both personnel and tools.

High Frequency Electromagnetic Fields!

Exposure to strong high frequency electromagnetic fields may cause thermal damage to personnel. The eye (cornea and lens) is easily exposed.

Any unnecessary exposure is undesirable and should be avoided.

In radio-relay communication installations, ordinary setup for normal operation, the general RF radiation level will be well below the safety limit.

In the antennas and directly in front of them the RF intensity normally will exceed the danger level, within limited portions of space.

Dangerous radiation may be found in the neighborhood of open waveguide flanges or horns where the power is radiated into space.

To avoid dangerous radiation the following precautions must be taken:

During work within and close to the front of the antenna; make sure that transmitters will remain turned off.

Before opening coaxial - or waveguide connectors carrying RF power, turn off transmitters.

Consider any incidentally open RF connector as carrying power, until otherwise proved. Do not look into coaxial connectors at closer than reading distance (30 cm). Do not look into an open waveguide unless you are absolutely sure that the power is turned off.

1. Introduction

This chapter provides an overview of the Evolution IP-20 Long Haul (IP-20LH), Ceragons next generation multi-carrier long-haul solution. IP-20LH is designed for ultra-high flexibility and modularity. It is optimized for nodal deployment, with a small footprint, high density, and a high degree of scalability and availability.

The Evolution IP-20LH enables operators to deploy high capacity, long haul microwave systems in locations where rack space and shelter real-estate are limited. Evolution IP-20LH supports multi-carrier solutions of up to 8+0 ABC and IF Combining Space Diversity.

Lowering costs further, the systems ultra-high power transmitter transmits the highest power in the industry, and can reach longer distances using smaller antennas. For maximum power efficiency, the Evolution IP-20LH incorporates a dynamic biasing technique that minimizes the power consumption of the system to the minimum required to deliver the required Tx power while, at the same time, reducing the systems heat dissipation. In addition, installation labor cost and electricity consumption are reduced, achieving an overall diminished carbon footprint.

The IP-20 series pay-as-you-go licensing models enable operators to build for the future by adding capacity and functionality over time to meet the needs of network growth without the need to add additional hardware. Additionally, IP-20LHs modular structure provides for the gradual expansion of network nodes through the addition of line and radio cards, utilizing a single 1RU or 2RU chassis.

2. Evolution IP-20LH Hardware Overview

The Evolution IP-20LH is a modular unit based on a 1RU or 2RU chassis into which a variety of cards can be inserted for traffic, radio interface, management, and power supply. The IP-20LH backplane provides connectivity among the slots in the chassis for management, power distribution, and traffic aggregation.

An IP-20LH chassis and the cards it contains are managed by a Traffic Control Card (TCC). A 2RU IP-20LH can hold two TCCs for redundancy1. TCCs include two GbE combo interfaces for Ethernet traffic and two FE interfaces for management.

Note: In a redundant TCC configuration, the GbE traffic interfaces on the TCC are disabled.

Radio Module Cards (RMCs) are responsible for the interface between the IP-20LH and the XCVRs. A 1RU IP-20LH can hold up to four RMCs. A 2RU IP-20LH can hold up to eight RMCs.

Line Interface Cards (LICs) can be added to provide additional traffic interfaces. Ethernet and TDM LICs can be used. A 2RU chassis can contain up to ten LICs, up to two of which can be Ethernet LICs. A 1RU chassis can contain up to five LICs, one of which can be an Ethernet LIC.

Note: In a 2RU chassis with two Ethernet LICs, the GbE interfaces on the TCC are disabled.

The IP-20LH receives an external supply of -48V via a Power Distribution Card (PDC). A 2RU IP-20LH chassis can hold two PDCs (for card redundancy). The PDC or PDCs distribute the power via the backplane to all the modules in the chassis.

IP-20LH provides two basic chassis options:

1RU Fits in a single ETSI rack slot, with one Main Traffic and Control Card (TCC), four universal slots for a combination of up to four Radio Interface Cards (RMCs) and/or Line Cards for traffic (LICs), and a Power Distribution Card (PDC).

2RU Fits in two ETSI rack slots, with two Main Traffic and Control Cards (TCCs), eight universal slots for a combination of up to eight Radio Interface Cards (RMCs) and/or Line Cards for traffic (LICs), and two Power Distribution Cards (PDCs).

1 TCC redundancy is planned for future release.

2.7 Power Distribution Card (PDC)

Evolution IP-20LH receives an external supply of 48V current via one or two Power Distribution Cards (PDCs). The PDC or PDCs distribute the power via the backplane to all the modules in the chassis. Each module receives the 48V input and regulates it down to the operating voltage required by that module. XCVRs are powered from the PDC, via the RMC that is connected to the XCVR.

The PDC monitors the power supply for under-voltage. The PDC includes a LED labeled ACT, which displays Green during normal operation. If the voltage goes below -38V, the LED displays Red. When the voltage returns to -40V or higher, the Red indication goes off and the Green indication reappears.

The PDC includes reverse polarity protection, so that if the positive (+) and negative (-) inputs are mixed up, the system remains shutdown.

The PDC can tolerate up-to -60V, with a maximum current of 30A.

A 1RU IP-20LH includes a single power distribution card (PDC) with a dual-feed option for power redundancy. With the dual-feed option, users can connect two power supplies to the PDC for power redundancy.

A 2RU IP-20LH can use two PDC cards for redundancy. Each PDC provides 48V power to all modules in the chassis via the backplane, on different lines. A diode bridge in the modules prevents power spikes and unstable power from the two power sources.

Note: If the power is below -38V, the power supply to the TCC is automatically shut down.



2.8 Fans Module

The fans module contains four 48V fans, which can dissipate heat for systems up to 270W. The fans draw air into one side of the chassis, and push the air through the chassis and out the other side.

Fans Module Detailed View

The fan speed increases and decreases in response to the temperature inside the chassis. When the temperature rises, the fan speed increases, and when the temperature decreases, the fan speed decreases. The fan speed never decreases below a minimum level regardless of temperature.

9.1.2 Connecting to the Unit with a LAN Connection

Connect an Ethernet cable from the LAN port on the laptop or PC you are using to configure the unit to one of the management interfaces (MGMT1 or MGMT2) on the TCC.

Management Interfaces on the TCC

To establish a connection with the IP-20LH unit, it is necessary to have an IP address on the PC or laptop within the same subnet as the IP-20LH unit. The default chassis IP address is 192.168.1.1. For example, you can set the PC or laptop address to 192.168.1.10 and the subnet mask to 255.255.255.0. Note the initial settings before changing.

Note: The chassis IP address, as well as password, should be changed before the system is set in operation. For more information on these procedures, see DOC-00036540, IP-20N User Guide.

1 Select Control Panel> All Control Panel Items >Network and Sharing Center.

2 Click Change adapter settings.

3 Select Local Area Connection> Properties> Internet Protocol Version 4 (TCP/IP).

IP address: 192.168.1.10

Subnet mask 255.255.255.0

No default gateway

4 Press OK to apply the settings.



9.2 Logging On

1 Open an Internet browser (Internet Explorer or Mozilla Firefox).

2 Type in the default IP address "192.168.1.1" in the Address Bar.

3 Enter the following values:

User Name: admin

Password: admin

4 Click Apply.



9.3 Configuration

Before connection over the radio hop is established, it is of high importance that the elements are assigned a dedicated IP address, according to an IP plan for the total network.

Note: If connection over the hop is established with identical IP addresses, an IP address conflict will occur, and remote connection to the element on the other side of the hop may be lost.

By default all elements have the same IP settings:

IP address: 192.168.1.1

Subnet mask: 255.255.255.0

Note: After the new IP address is set, the contact with the element will be lost. In order to reconnect, the PC must have an IP address within the same subnet as the element.

In addition to setting the IP addresses, the following configuration steps should be performed in order to establish basic connectivity. For a detailed description of these procedures, refer to the Evolution IP-20LH User Guide, DOC-00043450.

10. Interfaces and Pin-Outs

10.1 TCC Interfaces and Pin-Outs

A TCC contains two GbE Ethernet interfaces and two FE interfaces for management.

For the GbE interfaces, you can choose between two optical (SFP) and two electrical (RJ-45) physical interfaces. The electrical interfaces are labeled GbE1 and GbE2. The optical interfaces are labeled SFP1 and SFP2. The optical interfaces are located to the right of the electrical interfaces.

The FE management interfaces are labeled MGMT1 and MGMT2. These interfaces are 100BaseT with auto negotiation and auto crossover.

A TCC also contains the following interfaces:

One RJ-45 terminal interface (RS-232)

One DB-9 interface for external alarms, supporting four pairs of signals

One RJ-45 synchronization interface for clock input and output
