5-14 Subsystem Maintenance
ƒ Replacing a cooling module: When you are notified that a cooling module
has failed, it should be replaced as soon as possible. A failed cooling
module should only be removed from the subsystem when you have a
replacement module that can be installed as soon as the failed cooling
module has been removed.
WARNING!
It is not advisable to run the subsystem with a single cooling module for a
long period of time. If the second cooling module fails, the system is at
risk of sustaining irreparable damage.
5.5.2 Replacing a Cooling Module
To replace a cooling module, please follow these instructions:
Step 1. Remove the cooling module by pressing the slide lock on the
side of the module towards the center of the chassis and then
pulling the module out of the chassis.

Step 2. Gently slide the new cooling module into the chassis. Do not
use force or slam the module. The slide lock will hold the
module in place. If the cooling module is added online, the
respective cooling fan LEDs should light constant green.
