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.

However, an IOM uses the same latching mechanism as the controller module.
5. Swing the latch handle open, then grip the latch handle and ease the IOM forward from the slot.
6. Place both hands on the IOM body, and pull it straight out of the enclosure such that the IOM remains level during removal.
Installing an IOM
Before you begin any procedure, see
1. Examine the IOM for damage, and closely inspect the interface connector. Do not install the IOM if the pins are bent.
2. Grasp the IOM using both hands, and with the latch in the open position, orient the IOM and align it for insertion into the target slot.
