Removing a Blower Module
Removing a Blower Module
To remove a blower module, perform the following steps:
Step 1
Ground yourself using an approved ground wrist strap.
Step 2
Unfasten the captive screw.
Step 3
Pull the blower module toward you until it completely disengages from the chassis.
Step 4
Insert a replacement blower module into the empty chassis bay to ensure appropriate cooling.
Note
Each blower module contains two blowers for a total of four blowers. The system can tolerate
one out of four blowers failing. When you remove a blower module, you have three minutes to
replace it with a fully-functioning blower module.
