Prepare the software environment to remove the drive.

See your operating system documentation for instructions and procedures 
required to remove a disk module. It may be necessary to unmount file systems 
associated with the disk drives installed in the disk system.

3

Unlatch the disk module handle and remove the disk module. 

Squeeze the latch to unlock the disk module. Put a finger behind the latch and 
pull the disk module out until it disengages from the backplane. Leave it in its 
slot for two to three minutes to allow the disk drive to spin down before removing 
the disk module from the enclosure.

If you are going to replace the disk module immediately, refer to “Replace a Disk 
Module” below.

If you are not going to replace the disk module immediately insert a filler panel 
into the open slot to assure the required cooling.

Replace a Disk Module

1

Refer to your operating system documentation for requirements and procedures 
for replacing disk modules.

2

Align the replacement disk module with the disk module slot.

3

Slide the disk module into the slot until it engages with the backplane.

4

Press on the locking handle until it locks. You will hear an audible click when the 
locking mechanism is fully engaged.
