faceplate and that the side with screw holes should be
facing up.
Do this with a precisely vertical motion.
Step 6.
Once the fan is fully inserted, pull the release tab
backward to its original position so that the cooling
module’s connector can correctly mate with the
connector in the module bay. Fasten the retention
screw next to the release tab.
Step 7.
Secure the module
by fastening the screws you
previously removed.
Step 8.

Hard Drive Maintenance Overview
Hot-swappable drive trays:
The drive trays are all hot-
swappable. A disk drive failure can be corrected online.
Handles:
If the failed hard drive is behind either the left- or right-
side forearm handle, unfold the handles to access the drive trays.
Open flap:
Once the front flap on the drive tray has been
opened, the drive tray must be removed from the subsystem.
Failure to remove the drive tray from the subsystem after the
front flap has been opened may cause data errors.
Slowly remove a faulty drive:
When removing a drive tray from
the subsystem, pull the drive tray out only about one inch and
then wait for at least 30 seconds for the hard drive motor to spin
down before taking it out completely. Any impact to the hard
drive while the drive motor is spinning can damage the hard
drive.
There are situations that healthy drives can be removed. In
operations such as Copying & Replacing member drives with
drives of larger capacity, you may need the replaced disk drives
in other installations.
