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.
