Fans; Replacing The Fans - Gateway 8450R System Manual

Fans

The server contains six hot-pluggable fans to keep the internal temperature
down to acceptable levels.

Replacing the fans

The fans are located between the electronics bay and the drive bays. The fans
are hot-plug capable so you do not need shut down the server to replace a fan.
To replace a fan:
1
Remove the back top panel. (See "Removing the back top panel" on
page 28 and "Preventing static electricity discharge" on page 25.)
2
Determine which fan has failed by looking at the fan status LEDs in the
fan tray.
