5.3.2. Cooling Fans
The LaCie 12big Rack Network enclosure system incorporates ten
cooling fans, housed in a Cooling Cage. Fan modules are individu-
ally installed.
IMPORTANT INFO:
A faulty Cooling Fan must be replaced by a
fully operational Cooling Fan within 72 hours. Do not remove the
faulty module until you have a replacement module of the same
type available.
5.3.2.1. Removing a Cooling Fan
CAUTION:
The enclosure top cover should only be opened by ser-
vice personnel as it provides access to a service area.
Potential hazards include:
✦
Rotating fans
✦
Hot surfaces
Upon replacement, the cover MUST be secured by turning the lock
mechanism to the “locked” position with a screwdriver.
1. To access the ten Cooling Fans, release the enclosure top cover
by turning the lock mechanism to the “unlocked” position and
slide the cover back until it stops (see
Fig. 25
).
2. Grip the faulty Fan module with finger and thumb and pull it
upwards in order to unplug it from the Enclosure Management
PCB and remove it from the enclosure (see
Fig. 26
).
CAUTION:
Ensure the fan has stopped rotating before you attempt
to remove it. Risk of trapping or cutting fingers.
