Before installing the enclosure, verify the existence of the following:
•
Depending upon the controller module: SAS, Fibre Channel (FC), or iSCSI HBA and appropriate switches (if used)
•
Qualified cable options for host connection
•
One power cord per PCM or PSU
•
Rail kit (for rack installation)
Contact your supplier for a list of qualified accessories for use with the enclosure. The accessories box contains the power cords and other
accessories.
Required tools
The following tools are required to install an ME4 Series enclosure:
•
Phillips screwdriver
•
Torx T20 bit for locks and select CRU replacement
Requirements for rackmount installation
You can install the enclosure in an industry standard 19-inch cabinet capable of holding 2U form factors.
NOTE:
See the
Dell EMC PowerVault ME4 Series Owner's Manual
for front and rear panel product views.
•
Minimum depth: 707 mm (27.83") from rack posts to maximum extremity of enclosure (includes rear panel cabling and cable bend
radii).
•
Weight:
•
Up to 32 kg (71 lb), dependent upon configuration, per 2U enclosure.
•
Up to 128 kg (282 lb), dependent upon configuration, per 5U enclosure.
•
The rack should cause a maximum back pressure of 5 pascals (0.5 mm water gauge).
•
Before you begin, ensure that you have adequate clearance in front of the rack for installing the rails.
Disk drive module
The ME4 Series Storage System supports different disk drive modules for use in 2U and 5U84 enclosures.
•
The disk drive modules that are used in 2U enclosures are referred to as drive carrier modules.
•
The disk drive modules that are used in 5U84 enclosures are referred to as Disk Drive in Carrier (DDIC) modules.
Drive carrier module in 2U chassis
The drive carrier module consists of a disk drive that is installed in a carrier module.
•
Each 2U12 drive slot holds a single low profile 1.0 in. high, 3.5 in. form factor disk drive in its carrier. The disk drives are horizontal. A
2.5" to 3.5" carrier adapter is available to accommodate 2.5" disk drives.
•
Each 2U24 drive slot holds a single low profile 5/8 inch high, 2.5 in. form factor disk drive in its carrier. The disk drives are vertical.
The carriers have mounting locations for:
•
Direct dock SAS drives.
A sheet steel carrier holds each drive, which provides thermal conduction, radio frequency, and electro-magnetic induction protection, and
physically protects the drive.
The front cap also has an ergonomic handle which gives the following functions:
•
Secure location of the carrier into and out of drive slots.
•
Positive spring-loading of the drive/midplane connector.
The carrier can use this interface:
•
Dual path direct dock Serial Attached SCSI.
