Removing a Fan CRU Without an Ejector

To remove a fan CRU that does not have an ejector, follow this procedure (see

Figure 4-3):

1. Supporting the fan CRU with both hands, unlatch the fan CRU by pulling on the left

side handle to disengage the snap studs of the fan CRU from the back section of the

45xx module.

2. Lift the fan CRU back and away from the module.

Installing a Fan CRU (Without Ejector)

To install a fan CRU that does not have an ejector, follow this procedure (see

Figure 4-3):

1. Insert the interface bracket on the right-hand side of the fan CRU into the slots on

the right-hand wall of the back section of the 45xx module.

2. Make sure that the snap studs on the left-hand side of the fan CRU are aligned with

the holes in the back section of the module. The snap studs have rounded ends that

fit snugly into these holes.

3. Gently press the left-hand side of the fan CRU against the back section of the

module until the snap studs snap into place. Both fans begin to spin as soon as the

power connector on the fan CRU engages the socket in the module.

Make sure that any power cords or fiber-optic cables for this module are routed

cleanly through the cutouts and into the extrusion channels on the side of the stack.

Caution. Press gently on the fan CRU. Using too much force to attach the fan CRU can shock

and possibly damage the disk drives.
