Attach or remove the front bezel of a 2U enclosure
The following figure shows a partial view of a 2U12 enclosure:
Figure 37. Attaching or removing the 2U enclosure front bezel
To attach the front bezel to the 2U enclosure:
1. Locate the bezel, and while grasping it with your hands, face the front panel of the 2U12 or 2U24 enclosure.
2. Hook the right end of the bezel onto the right ear cover of the storage system.
3. Insert the left end of the bezel into the securing slot until the release latch snaps in place.
4. Secure the bezel with the keylock as shown in Attaching or removing the 2U enclosure front bezel.
To remove the bezel from the 2U enclosure, reverse the order of the preceding steps.
NOTE: See Enclosure variants for details about various enclosure options.
Replacing a drive carrier module in a 2U enclosure
The section describes how to replace a drive carrier module in a 2U enclosure.
A drive carrier module consists of a disk drive that is installed in a carrier module. Drive carrier modules are hot-swappable,
which means they can be replaced without halting I/O to the disk groups, or powering off the enclosure. The new disk drive
must be of the same type of drive and contain a capacity equal to or greater than the drive being replaced. Otherwise, the
storage system cannot use the new disk drive to reconstruct the disk group.
CAUTION:
● Removing a drive carrier module impacts the airflow and cooling ability of the enclosure. If the internal
temperature exceeds acceptable limits, the enclosure may overheat and automatically shut down or restart.
● When removing a drive carrier module, wait 30 seconds after unseating the drive carrier module to allow the
disk drive to stop spinning.
NOTE:
● Familiarize yourself with full disk encryption (FDE) considerations relative to disk drive installation and replacement.
● When moving FDE-capable disk drives for a disk group, stop I/O to the disk group before removing the drive carrier
modules. Import the keys for the disk drives so that the drive content becomes available. See the Dell EMC PowerVault
ME4 Series Storage System Administrator’s Guide or Dell EMC PowerVault ME4 Series Storage System CLI Guide for
more information.
Before you begin any of the procedures, see the ESD precautions on page 42.
