Checking the Main Hub’s LEDs
• The LEDs should blink through all states on power up.
• If the LEDs do not blink on power up, replace the Main Hub.
• If the LEDs do not illuminate at all, make sure the AC power cable is con-
nected.
• For each fiber optic port that has a Main Hub connected:
•The
LINK LED should be green.
•The
E-HUB/RAU LED should be:
– Green if the
MAIN HUB STATUS is green.
– Red if the
MAIN HUB STATUS is red.
•The
MAIN HUB STATUS LED should be:
• Red if the Main Hub is new from the factory and a band has not been pro-
grammed, or if the wrong band is programmed.
• Green if the Main Hub was previously programmed with a correct band
(matches the RAUs in the system).
NOTE: If there is communication between the Main Hub and the Expansion Hubs,
use the AdminManager software’s Configuration & Maintenance panel to isolate sys-
tem problems.
