Checking For Proper LVS Operation
Inspection holes are provided at the rear of the rack in order to
verify whether the two rack power supply (LVS) units are working
properly. Each LVS has a green LED indicator which should be lit
when power is applied to the rack.
At rear of rack, ensure proper operation of LVS units by checking
LED status as follows:
Both LEDs lit: Status okay, both LVS units operating properly.
One LED lit: Status okay, but indicates that one LVS unit is not
working and should be replaced.
No LEDs lit: Failure situation, both LVS units need to be
replaced.
