Owners Manual

Enclosure management
The enclosure is mechanically and electrically compliant with the Storage Bridge Bay (SBB) v 2.1 specification.
SBB modules actively manage the enclosure. Each module has a SAS expander with its own storage enclosure processor (SEP)
that provides a SES target for a host to interface to, through the ANSI SES (SCSI Enclosure Services) standard. If one of these
modules fails, the other module continues to operate.
Management interfaces
When the hardware installation is complete, access the controller module web-based management interface—PowerVault
Manager—to configure, monitor, and manage the storage system. The controller module also provides a command-line interface
(CLI) to support command line entry and scripting. For details, see the Dell EMC PowerVault ME4 Series Storage System CLI
Guide for your system.
Operation
CAUTION: Operation of the enclosure with any CRU modules missing will disrupt the airflow, and the enclosure
will not receive sufficient cooling. It is essential that all slots hold modules before the enclosure system is used.
Empty drive slots (bays) in 2U enclosures must hold blank drive carrier modules.
● Read the module bay caution label affixed to the module being replaced.
● Replace a defective power cooling module (PCM) with a fully operational PCM within 24 hours. Do not remove a defective
PCM unless you have a replacement model of the correct type ready for insertion.
● Before removal/replacement of a PCM or power supply unit (PSU), disconnect power supply from the module to be
replaced.
● Read the hazardous voltage warning label affixed to power cooling modules.
CAUTION: 5U84 enclosures only
● To prevent overturning, drawer interlocks stop users from opening both drawers at the same time. Do not attempt to force
open a drawer when the other drawer in the enclosure is already open. In a rack containing more than one 5U84 enclosure,
do not open more than one drawer per rack at a time.
● Read the hot surface label affixed to the drawer. Operating temperatures inside enclosure drawers can reach 60ºC. Take
care when opening drawers and removing DDICs.
● Due to product acoustics, ear protection should be worn during prolonged exposure to the product in operation.
● Open drawers must not be used to support any other objects or equipment.
NOTE: See Enclosure variants on page 10 for details about various enclosure options.
