Replacing hot-swap fans
The server comes with four hot-swap fans: two front fans (fans 1 and 2), and two
center fans (fans 3 and 4). You do not have to turn off the power to the server to
replace a hot-swap fan.
If the server is equipped with the IBM xSeries 670-Watt Hot-swap Power-Supply
option, two rear fans (fans 5 and 6) must also be installed on the server. For
information on replacing these fans or installing this option, see "Replacing a rear
fan (5 or 6)" on page 21 or "Installing the 670-Watt hot-swap power-supply option"
on page 23.
Attention:
The following illustration shows how to replace hot-swap fans.
Determine which fan to replace by checking the LEDs on the fans. The front fans,
center fans, and rear fans are installed differently from each other. This section
contains separate instructions for each group of fans.
To help ensure proper cooling, if a fan fails, replace it within 48 hours.
