Removing and Replacing a Hot-Swappable Server Fan
When removing a hot-swappable server fan from the server, there are different procedures
depending on if you have a Data Center server or an Office Friendly server.
Data Center Server
Twelve fans cool the Data Center server. The fans are all redundant, hot-swappable, and
interchangeable. Fans 1 through 8 are located in a removable fan carrier directly behind the front
bezel. Fan units 9 through 12 are located in a removable I/O fan carrier between the SAS
backplane and the I/O card cage. The server is set up into three cooling zones. Fans 1 through
4 cool Zone 1. Fans 5 through 8 cool Zone 2. Fans 9 through 12 cool Zone 3. Each zone can
have one fan failure and still run, with the other fans in the zone speeding up until the failed fan
is replaced. Replace the fans using the procedures in this section whether the server is powered
on or off.
