Replacing a blank drive carrier module
Ensure optimal cooling throughout the enclosure by installing blank drive carrier modules into all unused drive slots.
To remove a blank drive carrier module, press the latch on the module and pull the module out of the drive slot.
To install a blank drive carrier module, insert the module into the drive slot and push the module into the drive slot to secure it in
place.
Replacing a DDIC in a 5U enclosure
The section describes how to replace a Disk Drive in Carrier (DDIC) in a 5U enclosure.
A DDIC consists of a disk drive that is installed in a carrier module. DDICs 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 DDIC 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 DDIC, wait 30 seconds after unlocking the DDIC from its seated position 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 DDICs.
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.
Accessing the drawers of a 5U84 chassis
The replacement procedure for DDICs must be completed within two minutes of opening a drawer.
Opening a drawer
1. Verify that the anti-tamper locks are not engaged. The red arrows on the locks point inwards if the locks are disengaged as
shown in the following figure. If necessary, unlock them by rotating counter-clockwise using a Torx T20 bit.
