Replacing a Server Fan
When a fan requires replacement, you will receive an e-mail Alert indicating that there is a
problem with one of your WD Sentinel server fans.
The fans in the WD Sentinel server are “cold swappable.” This means that the WD Sentinel
server must be shut down prior to your fan replacement. To shut down your WD Sentinel
server, follow the steps outline in “Shutting Down the Server” on page 45.
What you’ll Need:
Phillips screwdriver
Replacement server fan
