Diagnosing Problems with the Power Supply
If, during installation or after turning ON the hub, you suspect that power is not reaching
all ATM modules in the hub, see if the problem is caused by one of the conditions
described below. If you cannot solve the problem and if the 6416SW ACTIVE LED
does not light ON, contact an 3Com service representative before configuring the ATM
subsystem.

1. Refer to the
3Com ONcore Hub Installation and Operation Guide
(17-00362).
