1 Safety Precautions

PLEASE READ THESE SAFETY PRECAUTIONS!

RF Energy Health Hazard This symbol indicates a risk of personal injury due to radio frequency exposure.

The radio equipment described in this guide uses radio frequency transmitters. Do not allow people to come in close proximity to the front of the antenna while the transmitter is operating. The antenna will be professional installed on fixed-mounted outdoor permanent structures to provide separation from any other antenna and all persons.

WARNING: RF Energy Exposure Limits and Applicable Rules for 6-38 GHz. It is recommended that the radio equipment operator refer to the RF exposure rules and precaution for each frequency band and other applicable rules and precautions with respect to transmitters, facilities, and operations that may affect the environment due to RF emissions for each radio equipment deployment site.

Appropriate warning signs must be properly placed and posted at the equipment site and access entries.

Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

Do not turn on power before reading Cielo Network’s product documentation. This device has a ­48 VDC direct current input.

Protection from RF Burns It is hazardous to look into or stand in front of an active antenna aperture. Do not stand in front of or look into an antenna without first ensuring the associated transmitter or transmitters are switched off. Do not look into the waveguide port of an ODU (if applicable) when the radio is active.

An optional mount is available for mounting two SkyLink CG IDUs side-by-side in a 19-inch rack. Contact Cielo Networks for additional information.

3.1.3 Power

The IDU is shipped with a DC power port connector. The pinout is as follows:

Figure 8 – SkyLink CG Power Connector

The IDU does not have a power on-off switch. Once power is connected to the IDU the unit will turn on. Therefore, it is recommended to verify –48 VDC on the power supply connector prior to connecting to the IDU.

Connect the IDU power cable to the –48 VDC power supply. Using a voltmeter, connect the positive voltmeter probe on pin 1 (-48V) of the DC connector and the negative probe on pin 4 (PS Return). The connector screw heads may be used as probe points. Turn on the power supply and confirm the voltmeter reads between –44 VDC and –52 VDC. Adjust the power supply output voltage or change the connections at the power supply to achieve this reading.

3.1.4 Grounding

The IDU should be mounted in a rack that is connected to a ground point. The IDU includes a ground point on the front panel. Use the ground cable included with the IDU to the rack ground.

3.1.5 IDU-ODU Coaxial Cable

The IDU has an N-Female Connector for connecting the IDU to the ODU. The coaxial cable carries –48 VDC to power the ODU, Transmit IF (to ODU) at 350 MHz, and Receive IF (from ODU) at 140 MHz. IDU – ODU telemetry uses 5.5 and 10 MHz. Ensure the surge arrestor used meets these requirements. Contact Cielo Networks for recommended surge arrestors.

IDU-ODU cable distances are based on the type of cable used.

Table 3 - Max IDU-ODU Cable Connection Length

Cielo recommends installing two surge arrestors per terminal. One at the grounding block at the enclosure entrance for the IDU and the second at the ODU.

3.1.6 Customer Ethernet Port

The SkyLink CG IDU has a primary User port for customer traffic. The port is labeled “LAN A” and is a 10/100/1000BaseT Gigabit Ethernet port.

The LAN A Ethernet port supports management connectivity to the SkyLink CG IDU when configured to support In-Band Management.

3.1.7 TDM Ports

The SkyLink CG IDU supports optional 2xT1/E1 or 1xDS3/E3 HSI (High Speed Interface) modules. The module simply plugs in to the HSI slot and is automatically detected by the SkyLink CG IDU.

3.1.8 IDU Network Management Interface

The SkyLink CG IDU “LAN B” port is primarily considered the NMS port. Alternatively this 10/100BaseT Fast Ethernet port can be used for user traffic. Proper network planning is required if connecting to both LAN A and LAN B ports on the SkyLink CG IDU. These ports can be tied connected together internally in the SkyLink CG IDU – possibly forming an Ethernet loop back to the customer network. LAN A and LAN B ports should not be connected to the same external Ethernet switch unless the ports are properly configured.

4 SkyLink CG IDU Configuration

This section defines the basic settings required to configure the SkyLink CG IDU in order to turn up and align the microwave radio link.

For SkyLink CG IDU configuration it is recommended to have the IDU and ODU connected. Doing so allows the IDU to be fully configured, including frequency and power settings for the radio link. If the ODU is not connected, the frequency and power setting cannot be configured.

4.1 Management Connection

Configuration of the SkyLink CG IDU is possible via the following connections:

10/100BaseT NMS/LAN B Port

o Recommended method

o Supports Local and Remote Configuration

o Configuration via Web GUI or Telnet

RS232 Serial Port Interface

o Serial cable, such as Cisco type console cable required

o Supports local configuration only

o Configuration via HyperTerminal

o Useful when IP address of IDU is not known

The following section addresses configuration via the Web GUI using the Ethernet NMS port only. Configuration via Telnet or HyperTerminal is CLI based. Contact Cielo Networks for additional information regarding CLI configuration.

The connection to the SkyLink IDU is made via a CAT-5 Ethernet cable for Web GUI. The SkyLink CG IDU ships with in-band management enabled. Connect to either the LAN A or LAN B ports.

The SkyLink CG is shipped with two default IP addresses:

Table 6 – SkyLink CG IDU Default IP Address

Primary Secondary

IP Address 192.168.0.1 10.10.10.10

Subnet Mask 255.255.255.0 255.255.255.0

SkyLink CG IDU Default IP Address

Page 22: Cielo Networks SkyLink CG Installation Manual

SkyLink CG Installation Manual

Page 22 Cielo Networks, Inc. – All Rights Reserved Rev 02/11

Figure 11 – SkyLink CG GUI – IP Settings default

Cielo Networks recommends that users leave the Secondary IP address at the default value (10.10.10.10 /24) for all deployed SkyLink CG IDUs. This allows the field engineer to use the Secondary IP address if the primary address is unknown. Alternatively, customers can change the secondary IP address. Cielo Networks does recommend that customers use the same secondary IP address consistently for all deployed SkyLink CG IDUs.

The Ethernet port of the installer’s PC used for configuration must be on the same subnet – 192.168.0.x (x = 3…254) or 10.10.10.x (x = 2…9, 11…254).

Launch a web browser and enter the IP address of the SkyLink CG IDU or click on the link below

4.3 IP Address Configuration

The instructions listed in this section of the manual are based on in-band management configuration of the IDUs (default setting). For out-of-band management configuration options please refer to the document “SkyLink CG Management IP Address Configuration”.

In order to communicate to the remote IDU both the local and remote side IP address have to be configured in both SkyLink CG IDUs.

Figure 13 - IP Address Configuration

Select the IP Tab for the Address Page.

Primary IP/Mask: Update to the deployed network’s specific requirements.

Secondary IP/Mask: o The secondary IP address provides a backup IP address to be used for access. o The secondary IP address is only recognized on the local IDU connected to the

users laptop. o Cielo Networks recommends leaving the value at default. o If the IP address conflicts with the installed network Cielo recommends changing

all deployed SkyLink CG IDUs Secondary IP address to the same value.

Gateway IP: IP address of gateway router.

Remote Side IP: IP address of far side IDU.

FTP/USB Server: No change required

Proxyarp: Leave unchecked.

Once apply is selected the changes will be written to W0 memory (start-up memory) followed by an IDU reboot.

Update your laptop IP Address accordingly with the new SkyLink CG IP Address values.

Note the user can move the cursor over the remote terminal on the top of the GUI screen to hyperlink to the remote IP address (shown in lower left corner of GUI).

4.4 Radio Link Configuration

Radio Link Configuration is required for both the local and remote SkyLink CG IDUs. Cielo recommends customers configure the IDUs in a staging area prior to deployment.

Select the “Radio” tab. The top sheet under the “Radio” tab is “Parameters”. The following values have to be changed to the specific values for the microwave link. See Figure 16

Setting o Local Only – Changes are applied to the local IDU only. For initial IDU

configuration with no connectivity to the far side IDU this can be chosen. o Local + Remote – Necessary when link is operational and applying any changes

to parameters with a “1)” next to the name.

TX Frequency o Set the TX frequency for the link per the FCC channel assignment. o The TX Frequency must be within the range of the connected ODU.

TXBand(T/R) shows the TX frequency range supported If the band shown is not the expected frequency range change the ODU to

the specific one defined for the site.

RX Frequency o Set the RX frequency for the link per the FCC channel assignment.

Page 26: Cielo Networks SkyLink CG Installation Manual

SkyLink CG Installation Manual

Page 26 Cielo Networks, Inc. – All Rights Reserved Rev 02/11

o The RX Frequency is either T/R added or subtracted from the TX frequency If the ODU is a TX Low, the RX Freq = TX Freq + T/R If the ODU is a TX High, the RX Freq = TX Freq – T/R The value “Actual T/R” is the difference between the TX Frequency and

RX Frequency input by the user. Verify the Actual T/R value is the same as the T/R supported by the ODU.

Max TX Power o Set Transmit Power to the licensed transmit value for the hop.

ATPC (Automatic Transmit Power Control) o This box should be left unchecked for path alignment. o Only enable if required for the hop once alignment is complete. o Contact Cielo Networks for additional information. o ATPC RxL box does not need to be changed.

ODU Mute o Auto – default setting. ODU is transmitting. o Muted – ODU transmitter is muted. o For link configuration leave at “auto”.

Actual/Modulation o The drop down list will provide the throughput options based on the purchased

key. o Select the modulation option for the IDU.

FEC Option

01 = More FEC Overhead – improved RX Sensitivity by 1 dB compared to 02.

02 = Less FEC Overhead – more user throughput. o The SkyLink CG IDU requires a Wideband Key for 40, 50, and 56 MHz channel

operation. If the dropdown list only shows 10 to 30 MHz channel options the IDU is

setup for narrow channel operation. For wideband channel operation select the Maintenance tab and go to the

Miscellaneous Sheet

Design Type 301: Narrow channel operation

Design Type 303: Wide channel operation

Figure 15 – SkyLink CG GUI Maintenance Page

For a deployed link, change the remote side first and then the local side IDU.

Note if changing from design type 303 to 301 the bandwidth throughput available over the radio link is typically less.

If user bandwidth requirements exceed the radio link bandwidth the far side NMS may be unreachable due to excess user bandwidth.

Increase the throughput of the link by increasing the modulation “Actual/Modulation” configuration.

o Must select setting of “local+remote” to update remote IDU.

Page 28: Cielo Networks SkyLink CG Installation Manual

SkyLink CG Installation Manual

Page 28 Cielo Networks, Inc. – All Rights Reserved Rev 02/11

ACM Operation o Leave unchecked for link installation and alignment. o Once the link is installed ACM operation can be enabled.

Apply Changes o Select Apply

Confirm “Local” for radio links that are not connected Select “Local + Remote” for radio links that are operational. Ensures

changes are applied to both IDUs and the link remains operational.

Auto Restore Configuration Protection o Note the SkyLink CG IDU includes a link protection mechanism in case an IDU is

mis-configured resulting in the link dropping. E.g. Modulation is applied to a “local” SkyLink CG IDU only instead of

“local+remote”. o Auto-Restore Configuration protection will reload the W0 configuration if the

modem is unlocked for 10 continuous minutes. o Auto-Restore Configuration is on the Maintenance – Miscellaneous page.

Figure 16 – SkyLink CG GUI Radio Parameters Page

4.4.1 Ports

The Ports page assigns radio link bandwidth for Ethernet and, if installed, T1/T3. This page allows the user to manage the bandwidth over the radio link. Especially when the user wants to provide less Ethernet bandwidth than the radio link offers.

Page 29: Cielo Networks SkyLink CG Installation Manual

SkyLink CG Installation Manual

Page 29 Cielo Networks, Inc. – All Rights Reserved Rev 02/11

The ports page will update if a T1 or T3 module is installed.

Page 30 Cielo Networks, Inc. – All Rights Reserved Rev 02/11

Figure 18 – SkyLink CG GUI – Ports Page with T3 module

The capacity shown at the top of the page shows the bandwidth available across the radio link

TDM Traffic (T3 or T1) is first subtracted from the bandwidth if module is installed and enabled.

Ethernet bandwidth o Change Speed value as required for the link. o The value in the Speed box can be higher than the radio link bandwidth available. o Alternatively the Speed can be less than the bandwidth available to limit user

throughput.

Ethernet Interface o Port page allows the user to change from the default configuration of Auto

Negotiation (ANEG) to a fixed port setting. o LAN box indicates the port negotiation. o If Manual Setting is selected the user must ensure the connecting Ethernet port is

also set for Manual operation

BER o A radio link BER test can be run on the radio link using un-allocated bandwidth. o Cielo Networks recommend that 2 Mbps of bandwidth be allocated for BER

testing. BER Test results shown on the Count page

o Mode options allows the user the type of BER test performed.

4.5 Save Configuration

Important Step

Select “Write W0” on upper right corner of the SkyLink CG GUI. Memory Bank 0 is the boot up configuration. Failure to save the configuration may result in the link becoming unavailable if power is temporarily lost of the system is rebooted.

Alternatively, other operational configurations can be saved to Memory Bank 1, 2, or 3. To run the link at these other configurations select R1, R2, or R3. Go to the Maintenance page for these options.

4.6 Link Alignment

The microwave radio link should be aligned to the RSL value defined for the hop.

RSL can be calculated using the following formula:

RSL (dBm) = PTX + GTX ANT – LPath + GRX ANT

Where: PTX is the transmitter output power (in dBm)

GTX ANT is the gain of the transmit antenna (in dB)

GRX ANT is the gain of the receive antenna (in dB)

LPath is the Path loss, defined by:

LP (dB) = 96.9 + 20log10(F*D)

Where: F is the Frequency in GHz; D is the Distance of path in miles

The ODU has a BNC port that provides a voltage that relates to the RSL of the link. Connect a digital voltmeter to the BNC port during the alignment process.

The following table defines the relation between RSL and the ODU BNC voltage measurement:
