FID 82: Power supply
Before you begin this procedure, see “Power problems MAP” on page 193 to isolate the failing power
supply.
See Figure 79 on page 251 for FRU location 82. Use Figure 80 on page 252 as you follow this procedure.
All 3592 dc power supplies are hot-pluggable. To minimize the impact on customer operations, one dc
power supply can be unplugged and removed while the remaining power supply continues to provide dc
power to both 3592 drives in the enclosure.
Attention: Do not disconnect the AC power from both power supplies in the same enclosure at the
same time, unless both drives in the enclosure are already offline, and you want to disconnect
power to both drives.

Note: It is not necessary to vary the drive offline or to make the drive unavailable to the customer if
you are removing only one power supply. If you are removing only one power supply, go to Step 2.

Replacing the power supply
1. Complete the Remove procedure in the reverse order, then return here.
2. Ensure that the AC and DC LEDs on the power supply are ON. See

in Figure 80 on page 252 for the
location of the LEDs.
3. Go to “End of call” on page 185.
