EMM

This section provides instructions for removing and installing an EMM in an enclosure.

The PowerVault MD2460 enclosure supports two redundant EMMs. If an EMM fails, the enclosure will run on a single EMM until

the redundancy is restored. You can replace one EMM without powering off the enclosure. However, if you do not have MPIO

configured on your system, Dell recommends that you stop all I/O before removing the EMM.

CAUTION:

When an EMM is removed from an enclosure, it must be replaced within 20 minutes to prevent the

enclosure from overheating.

CAUTION:

Before removing an EMM ensure that MPIO is configured on the host to direct I/O through redundant

cabling.

You might need to replace an EMM when:

● The EMM Status LED is blinking amber. See
