Checking the Main Hub’s LEDs
The LEDs should blink through a 5-second test 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 connected Expansion Hub, which has been pro-
grammed with a band, the
PORT LED should be green.
Refer to Section 9.3, “Troubleshooting,” on page 9-3 for more LED states.
NOTE: If there is no communication between the Main Hub and the Expansion
Hubs, use the AdminBrowser to isolate system problems.
