Removing the Power Supply Module
Determining Power Supply Status
If the LED on a power supply is off while the unit is powered on, and the power
cable is plugged in the corresponding power socket, then either the cable is faulty,
a fuse has blown, or the power supply itself has failed. To determine the possible
cause of the failure, follow these steps:
Step 1
Check the power cable to make sure that it is securely plugged into the unit. If the
cable is correctly attached, go to Step 2.
Step 2
Check the fuses by disconnecting the power cord and opening the fuse holder. If
the fuses are okay, swap out the failed power supply module.
Note
Check and replace the failed unit as soon as possible.While you
replace the faulty power supply, the redundant power supply
continues to provide uninterrupted service.
Note
The power socket labeled Power 1 supplies current to the left power
supply (Power 1). See Figure 3-11. The power socket labeled
Power 2 supplies current to the right power supply (Power 2).
