Replacing fans and fan modules

Your server comes equipped with several cooling fans and fan modules designed to provide sufficient airflow to keep your server running without overheating. These include:

■A system fan module with four, dual-rotor multi-speed fans to cool the processors, the memory, and the second and third hard drive bays (redundant when running low voltage processors).

■A single-rotor system fan to cool components in the full-height PCI zone, the power distribution board and the first hard drive bay.

■Two dual-rotor power supply fans to cool the power supply modules (redundant in the 1+1 power supply configuration)

Caution System fans are not hot-swappable. Before removing or replacing a fan, you must first turn off the server and all peripheral devices attached to the server, and remove the AC power cord(s) from the power supply or wall outlet.

System fans

System fans are monitored by the Gateway Server Manager (GSM), the mini-Baseboard Management Controller (BMC), and the Intel Management Module (IMM). All three reporting entities use a different numbering system to flag individual fans for attention.

Individual system fan module fan numbers are indicated on the top of the processor air duct. The first number in the pair is for the fan closest to the front of the server.
