5.5 Replacing a Faulty PSU Module

5.5.1 PSU Module Overview

•
Two (1+1) redundant PSU modules: The subsystem is preinstalled
with two (2) 530W, fully redundant, hot-swappable PSU modules.
These modules are located at the rear of the subsystem.
•
PSU canister: Each PSU module is housed in a robust steel canister,
with the power supply converter unit in the front and two serially-
aligned cooling fans in the rear section. When the PSU is removed
from the chassis, the cooling module is also being removed.
•
Printed text on PSU handle: Before you insert a new PSU, be sure that
the printed text on the sticker attached to PSU handle matches the same
printed text on a partner PSU. Double-check to avoid using a PSU of
previous Galaxy series. (See Figure 5-9)
•
Immediate replacement: When a PSU fails, it should be replaced
immediately. However, do not remove the PSU module unless a
replacement is readily available. Removing a PSU without a
replacement will cause severe disruptions to the internal airflow and the
subsystem will overheat and cause irreparable damage to some of the
subsystem components.
Replacing a Faulty PSU Module
replaced, contact your system vendor for a replacement controller
and return the controller module through the standard RMA
procedure.
