Replacing the fans

Types of fans

The appliance has three types of FRU fans, listed in the following table.

Note
Not all appliance fans are FRUs. The power supply fan and the heatsink fan in the C1200 are not FRUs.

Fan type	Quantity	Model number	Location of fan
Power supply fan	1	C2100 only	Part of the power supply chassis
CPU heatsink fan	1	C2100 only	Clipped onto the top of the CPU heatsink
Chassis fans	5/block	C1200	A block near the SCSI backplane
Chassis fans	3/block	C2100	A block near the SCSI backplane

When to replace fans

The C1200 and C2100 can continue to run with one failed chassis fan, but shut down if two or more fans fail. If possible, wait until a regularly scheduled maintenance period to replace a chassis fan in the C2100 or a chassis fan block in the C1200. The C2100 shuts down if the power supply fan or CPU heatsink fan fails, therefore requiring immediate replacement.
