Dell Storage MD1400 Enclosures Hardware Owner's Manual

Enclosure Management Module

An enclosure with redundant enclosure management contains two enclosure management modules (EMM). You can cable your enclosure either in a single port, redundant mode or in a multi-mode configuration. If only one EMM is installed in your enclosure, it must be installed in EMM 0. You must install the EMM blank in EMM 1.

NOTE: : EMMs can be removed and installed without turning off the enclosure.

CAUTION: : It is recommended that you do not remove an EMM while data is being transferred.

CAUTION: : Replacing or installing an EMM that is connected to a host server causes it to end communication with the enclosure and requires a restart of the host server.
