Removing a fan interconnect board
1. Schedule a maintenance window.
2. Stop all I/O to the enclosure.
3. Power down the enclosure by pressing and holding the On/Standby
button on the rear of disk enclosure, until the system power LED
changes from green to amber.
4. Remove all cabling from the rear of the enclosure. Ensure all cabling
is marked to facilitate re-cabling later.
WARNING!
A disk enclosure fully populated is heavy. Prior to
removing the enclosure from the rack, remove each
disk and label it with its bay number. Place each disk
on a clean surface. If this is not possible, two people
are required to remove the enclosure from the rack to
prevent injury.
5. Remove hard drives from the enclosure.
Press the release button on the drive lever (1), and rotate the lever
to the left (2).
Then, pull the disk drive out of the drive bays (3), leaving it in the
enclosure.
6. Loosen the thumbscrews that secure the enclosure to the front of the
rack, and remove the enclosure from the rack.
7. Remove the top access cover.
a. Lift the access panel latch (1). The access panel will slightly
disengage from the enclosure.
b. Slide the access panel to the rear (2) and lift away from the
chassis.
NOTE:
A Torx tool with T-10 and T-15 ends is provided inside
the enclosure chassis, on top of the I/O module
housing.
