5. 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.
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.
Replacing a power cooling module (PCM) in a 2U enclosure
This section provides procedures for removing and installing a PCM in a 2U enclosure.
The images in the PCM removal and installation procedures show rear panel views of the 2U enclosure.
A single PCM is sufficient to maintain operation of the enclosure. You need not halt operations and completely power-off
the enclosure when replacing only one PCM; however, a complete orderly shutdown is required if replacing both units
simultaneously.
CAUTION:
Do not remove the cover from the PCM due to danger from electric shock inside. Return the PCM to
your supplier for repair.
Before you begin any of the procedures, see the
NOTE:
The figures show PCM module replacement within the right slot as you view the enclosure rear panel. To replace a
PCM in the left slot, rotate the module 180º so that it properly aligns with its connectors on the back of the midplane.
Removing a power cooling module
CAUTION:
Removing a power supply unit significantly disrupts the enclosure's airflow. Do not remove a power
cooling module until you have received the replacement module on-hand. It is important that all slots are filled
when the enclosure is in operation.
Before removing the power cooling module, disconnect the power from the power cooling module by either the mains switch
(where present) or by physically removing the power source in order to ensure your system has warning of imminent power
shutdown. Ensure that you correctly identify the faulty power cooling module before beginning the procedure.
1. Stop all I/O from hosts to the enclosure.
NOTE:
This step is not required for hot-swapping. However, it is required when replacing both power cooling module at
once.
2. Use management software to shut down any other system components necessary.
NOTE:
This step is not required for hot-swapping. However, it is required when replacing both power cooling module at
once.
3. Turn off the faulty power cooling module, and disconnect the power supply cable.
4. If replacing a single power cooling module using hot-swap, proceed to step 6.
5. If replacing both power cooling module, verify that the enclosure was shut down using management interfaces, and that the
enclosure is powered off.
6. Verify that the power cable is disconnected.
7. Grasp the latch and the side of the power cooling module handle between thumb and forefinger, squeeze together and open
the handle to release the power cooling module and pull it half way out of the enclosure.
