Transporting Compactflash; Removing An Iom; Compactflash Memory Card Location - Dell EMC ME4 Series Owner's Manual

When two controller modules are installed in the enclosure, they must be of the same model type. When replacing both controller modules
in an operational enclosure, follow these guidelines:
1 Replace one controller as described in these instructions.
2 Wait 30 minutes: this pause ensures that the controller and its ownership of disk groups has sufficient time to stabilize. See
component operation.
3 Check the system status and event logs to verify that the system is stable.
4 Replace the partner controller as described in these instructions.

Transporting CompactFlash

This action applies to single-controller enclosure configurations only. To prevent data loss in this environment, the CompactFlash must be
moved from the failed controller to the new controller module.
CAUTION: Do not transport CompactFlash in a dual-controller environment. Doing so could cause data corruption.

Before you begin any procedure, see
1 Locate the CompactFlash memory card at the midplane-facing end of the failed controller module.
2 Grip the CompactFlash memory card and carefully pull it from the slot in the failed controller module.
3 Label the CompactFlash memory card as Data, and set it aside for safekeeping.
4 Locate the replacement controller module, and carefully remove its installed CompactFlash memory card.
a Take care not to confuse this diskette with the one labeled Data.
b Insert this CompactFlash memory card into the failed controller module.
5 Align the CompactFlash memory card labeled Data for insertion into the replacement controller module—then insert it into the slot—
and push it forward until seated in place.
