Installing and configure a replacement controller module in a single-controller module
enclosure
Perform the following steps to install and configure a replacement controller module in a single-controller module enclosure:
Before you begin any procedure, see
NOTE: For instructions on performing the following steps, see the Dell PowerVault ME5 Series Storage System
Deployment Guide.
1. Examine the controller module for damage, and closely inspect the interface connector. Do not install the controller module if
the pins are bent.
2. With the latch in the open position, grasp the controller module using both hands and align it for insertion into the target
slot.
3. Ensuring that the controller module is level, slide it into the enclosure until it stops.
A controller module that is only partially seated prevents optimal performance of the controller enclosure. Verify that the
controller module is fully seated before continuing.
4. Secure the controller module in position by manually closing the latch.
You should hear a click as the latch handle engages and secures the controller module to its connector on the back of the
midplane.
5. Reconnect the cables to the controller module.
CAUTION: If passive copper cables are connected to the controller module, the cable must not have a
connection to a common ground point.
6. Update the firmware on the controller module to the same version of the firmware that was on the failed controller module.
7. Configure the system settings and perform storage setup.
CAUTION: If the disk groups go into quarantine mode during the storage setup, contact technical support
before proceeding to the next step.
8. Reconfigure the connections to the host systems and remap the volumes.
9. Set up replications between storage systems.
Removing an IOM
Before you begin any procedure, see
NOTE: Considerations for removing IOM:
● Expansion enclosures are equipped with two IOMs. You may hot-swap a single IOM in an operational enclosure.
● If replacing both IOMs, and the expansion enclosure is online, you can hot-swap the IOM in slot "A", and then hot-swap
the IOM slot "B", verifying each module is recognized by the controller.
● Do not remove a faulty IOM unless its replacement is on-hand. All IOMs must be in place when the system is in
operation.
1. Locate the expansion enclosure containing the IOM that must be replaced. On the enclosure front panel, check for an amber
fault condition on the enclosure Ops panel. On the enclosure rear panel, look for amber illumination of the IOM Fault LED.
2. Disconnect any cables connected to the IOM.
Label each cable to facilitate re-connection to the replacement IOM.
3. Grasp the module latch between the thumb and forefinger, and squeeze the flange and handle together to release the latch
handle, and swing the latch handle out to release the IOM from its seated position.

4. Swing the latch handle open, then grip the latch handle and ease the IOM forward from the slot.
