Replacing a cooling fan

The SMC - Storage Array has ten fans in its cooling cage to ensure proper cooling

of the system. Each cooling fan can be individually replaced.

To replace a cooling fan, do the following:

CAUTION:

The enclosure cover should only be removed by qualified service personnel as it

provides access to a service area. Potential hazards include:

v Energy hazard

v Rotating fans

v Hot surfaces

v Access to PSU openings

Important:

After completing the fan replacement, be sure the enclosure cover is

properly closed and securely latched by turning the lock mechanism to the

locked position.:

1. Observe all safety and ESD precautions in the Safety and Warranty Guide.

2. Release the enclosure cover by using a flat-head screwdriver to turn the lock

mechanism to the “unlocked” position (see 1 in the following figure). Slide

the cover back until it stops (see 2).

3. Remove the faulty fan by carefully lifting it up, then unplug it from the

enclosure management PCB, and remove it from the enclosure.
