Removing an IOM:
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.
3. Label each cable to facilitate re-connection to the replacement IOM.
4. 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.
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:
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.
3. Ensuring that the IOM is level, slide it into the enclosure as far as it will go.
An IOM that is only partially seated will prevent optimal performance of the expansion enclosure. Verify that the IOM is fully seated before continuing.
4. Secure the IOM in position by manually closing the latch.
You should hear a click as the latch handle engages and secures the IOM to its connector on the back of the midplane.
5. Reconnect the cables.
