Planning for installation
Before beginning the enclosure installation, familiarize yourself with the system configuration requirements.

Location
Description
Drive carrier modules
2U front panel
All drive slots must hold either a drive carrier or blank drive carrier module. Empty slots
are not allowed. At least one disk must be installed.
DDIC
5U front panel
drawers
Maximum 84 disks are installed (42 disks per drawer). Minimum 28 disks are required.
Follow the drawer population rules in
Power cooling
modules
2U rear panel
Two PCMs provide full power redundancy, allowing the system to continue to operate
while a faulty PCM is replaced.
Power supply unit
modules
5U rear panel
Two PSUs provide full power redundancy, allowing the system to continue to operate
while a faulty PSU is replaced.
Fan cooling modules
5U rear panel
Five FCMs provide airflow circulation, maintaining all system components below the
maximum temperature allowed.
Controller modules
and IOMs
Rear panel
•
One or two controller modules may be installed in 2U12 and 2U24 enclosures.
•
Two controller modules must be installed in 5U84 enclosures.
•
Two IOMs must be installed in 2U12, 2U24, and 5U84 enclosures.
Preparing for installation
NOTE:
Enclosure configurations:
• 2U enclosures are delivered with CRUs and all drive carrier modules installed.
• 5U84 enclosures are delivered with CRUs installed; however, DDICs must be installed during system setup.
• 5U84 enclosures require 200–240VAC for operation. See the
Environmental requirements
topic in the
Dell EMC
PowerVault ME4 Series Storage System Owner’s Manual
for detailed information
CAUTION:
Lifting enclosures:
• A 2U enclosure, including all its component parts, is too heavy for one person to lift and install into the rack cabinet.
Two people are required to safely move a 2U enclosure.
• A 5U enclosure, which is delivered without DDICs installed, requires two people to lift it from the box. A mechanical
lift is required to hoist the enclosure for positioning in the rack.
Make sure that you wear an effective antistatic wrist or ankle strap and follow conventional ESD precautions when touching modules and
components. Do not touch the midplane, motherboard, or module connectors. See
requirements and handling procedures to use during product installation.
Preparing the site and host server
Before beginning the enclosure installation, verify that the site where you plan to install your storage system has the following:
•
Each redundant power supply module requires power from an independent source or a rack power distribution unit with
Uninterruptible Power Supply (UPS). 2U enclosures use standard AC power and the 5U84 enclosure requires high-line (high-voltage)
AC power.
•
A host computer configured with the appropriate software, BIOS, and drives. Contact your supplier for the correct software
configurations.
