Dell PowerEdge 2650

Accessing the Fans

The PowerEdge 2650 incorporates three different fan assemblies. The fans are hot-pluggable and fully redundant, meaning that any single fan in the system can fail and the remaining fans are able to cool the system adequately.

Since the fans are hot-pluggable, you can replace any single fan without shutting down the system. Each fan includes a connector that plugs directly into the system board, simplifying fan removal and installation.

Three different fan types are required in the PowerEdge 2650: power supply fans, PCI riser fans, and processor fans.

Power supply fans (2): mounted to the back of the chassis. Each system comes standard with two of these fans.

PCI riser fan (1): mounted on the PCI riser bracket. Each system comes with one fan mounted in this location, and it may be removed independently of the PCI riser assembly.

Processor fan (1 or 2): mounted to the processor and the heatsink assembly. Each system comes with a single fan per processor. If there are two processors in the system, there will be two processor fans. There is a mounting location for a second fan on each processor, in the event that future processor speeds require additional cooling.

IMPORTANT - More Information NOTE: Multiple assemblies were required to meet the cooling needs of the high performance Intel Xeon processors.

Below is a description of the fan numbering scheme; see the diagram for further clarification.

Fan Location Fan Number

Power Supply fan left (looking from the front) 1

Power Supply fan right (looking from the front) 2

Processor fan (secondary processor) 3

Processor fan (primary processor) 4

Riser Fan 7

IMPORTANT - More Information NOTE: Fan numbers 5 and 6 are reserved for future expansion.
