Diagnosing Problems from the 6416SW LEDs
After installing the 6416SW module, the following should occur when you turn ON the
ONcore hub:
All seven LEDs on the front panel light (ON) and then turn OFF, except for the
RUNNING LED.
The RUNNING LED stays lit (yellow).
After 7 seconds, the ACTIVE LED lights up and stays lit (yellow).
If the diagnostics are disabled, the ACTIVE LED lights up immediately and stays lit.
Some of the common problems that may arise with the 6416SW module after you turn
on the ONcore hub and the actions to take to solve them are shown below. If you find
that the ACTIVE LED still does not light ON after diagnosing these possible problems,
continue troubleshooting with “Diagnosing Problems with the Power Supply” on
page 7-9.
WRONG SLOT LED is ON.
Steps to Take:
1. 6416SW module is inserted in the wrong slot. Re-insert it in slots 9 and 10 or in
slots 11 and 12.
Note: Slots 11-12 on 17 slot models are used by the backup 6416SW. To use
them, make sure that slots 9 and 10 have a 6416SW installed.
After turning ON the hub, no LED stays lit except for the WRONG SLOT LED
which lights (ON) and then turns OFF.
