To clean the fiber ports:

Use compressed air to blow dust out of each fiber port before you insert the SC/APC

connector. Note that compressed air should not leave any residue as this will contam-

inate the fiber port.

To clean the fiber connectors:

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

the fiber connector front face is not free of dust or oils, follow the manufacturer’s rec-

ommendations for cleaning it.

To connect the fiber cables:

The fiber cable is labeled with either

1 or 2, or is color-coded. In addition to these

labels, you should add a code that identifies which port on the Main Hub is being

used and which Expansion Hub the cables are intended for. This differentiates the

connectors for proper connection between the Main Hub and Expansion Hubs.

If the fiber jumper is labeled with

1 or 2:

1. Connect 1 to UPLINK on Expansion Hub.

2. Connect 2 to DOWNLINK on Expansion Hub.

3. Label both ends of each cable with which Main Hub port is used.

For example:

First pair to Main Hub port 1: 11 (uplink), 12 (downlink);

Second pair to Main Hub port 2: 21 (uplink), 22 (downlink);

Third pair to Main Hub port 3: 31 (uplink), 32 (downlink); and so on.

4. Record which number you connected to UPLINK and DOWNLINK.

This information is needed when connecting the other end of the fiber cable to the

Main Hub’s fiber ports.

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

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

2. Connect “red” to DOWNLINK on Expansion Hub.
