394 Disk Enclosure Modules
Disk Enclosure Power Supply Module
!
Hot Swappable Component!
A failed power supply module should be replaced as soon as possible. When one power
supply fails, the remaining power supply will maintain the proper operating voltage for the
disk enclosure. However, if the remaining power supply fails before the first power supply
is replaced, all power will be lost to the disk enclosure.
C AUTION
Do not remove a power supply module until you have a replacement. An
empty slot will disrupt the cooling airflow within the enclosure and may
cause overheating.
Removing the Power Supply Module
1. Disconnect the power cord to the power supply.
2. Loosen the screw (B in Figure 98 ) from the power supply handle (A).
3. Pull the handle down to disengage the power supply from the backplane.
4. Slide the power supply out of the chassis. Support the power supply with your free hand
as it clears the chassis.
