To clean the fiber ends:

Be sure that the fiber cable’s SC/APC connectors are clean and free of dust or oils.

You will need lint-free cloths, isopropyl alcohol, and compressed air

1. Moisten a lint-free cloth with isopropyl alcohol.

2. Gently wipe the fiber end with the moistened cloth.

3. Using a dry lint-free cloth, gently wipe the fiber end.

4. Spray the compressed air away from the connector for a few seconds to clean out

the nozzle and then use it to completely dry the connector.

To connect the fiber cables:

The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection

between the Main Hub ports and the Expansion Hub ports, refer to the numbering or

color-coded connections you recorded when installing the Expansion Hub(s).

If the fiber jumper is labeled with

1 or 2:

1. Connect 1 to DOWNLINK on Expansion Hub.

The

DL STATUS LED should turn green as soon as you connect the fiber. If it does

not, there is a downlink problem. Make sure you are connecting the correct cable

to the port.

2. Connect 2 to UPLINK on Expansion Hub.

The

UL STATUS LED will turn green on the first Main Hub communication. It

may take up to 20 seconds to establish communication.

The Expansion Hub’s

E-HUB STATUS LED will turn green when the Main Hub

sends it the frequency band command.

If the

UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the

Main Hub LEDs. See page 7-17, item 2 in Table 7-5.

If the fiber jumper is color-coded (for example, “blue” or “red”):

1. Connect “blue” to DOWNLINK on Expansion Hub.
