Verifying component failure
Before replacing a disk, perform the following steps to ensure that you have correctly identified the module
requiring removal and replacement.
CAUTION: Failure to identify the correct disk drive module could result in data loss if the wrong disk is
removed from the enclosure. If your enclosure has a bezel installed, remove it to view disk LEDs.
When a disk drive fault occurs, the failed disk’s fault indicator LED, located on the enclosure’s front panel,
illuminates solid amber (see previous chapters for a description of LEDs and disk drive slot numbering for
your enclosure). You can determine from visual inspection which disk in the enclosure is experiencing a
fault/failure using the fault LED for your disk type.
NOTE: Product models use an enclosure bezel.
• See Attaching and removing the enclosure bezel on page 42 for 2U24 and 2U12 enclosure bezel
alignment, installation, and removal.
Removing a disk drive module
1. Follow one of two sub-steps below, according to your product disk drive module type (see Figure 31 ):
a. SFF disk (stands on edge) — Squeeze the latch release flanges together to disengage the disk drive
module, and swing the pivoting portion of the latch upwards by 45  (see Figure 31 and Figure 32
on page 48).
b. LFF disk (lays on side) — Slide the release latch to the left to disengage the disk drive module (see
Figure 31 ).
Moving the latch to the left will provide a clicking sound and cause the spring to move its position
inside the chassis, partially ejecting the disk from its installed position within the disk drive slot.

2. Wait 20 seconds for the internal disks to stop spinning.
3. Follow one of the two sub-steps below, according to your product disk drive type (see Figure 32 on
page 48):
a. SFF disk — Firmly grasp the front of the plastic sled, and pull the disk drive module straight out of
the chassis, taking care not to drop the module.
b. LFF disk — Once the disk drive module partially ejects from the slot, grasp the module firmly, and
carefully pull it straight out of the chassis slot. Take care not to drop the module.
