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.

Removing an EMM blank

CAUTION:
To maintain proper system cooling, make sure you install an EMM blank in the empty slot.
1. Remove EMM 0. See
Removing an EMM
2. To remove the EMM blank, press down on the release latch and pull the blank away from the enclosure.
