Verifying Component Operation - IBM Medium J11 Hardware Installation And Maintenance Manual

Note: When performing the following procedure, refer to Figure 41 on page 68 and Figure 40 on page 68
while ignoring the directional arrow. For installation, the IOM will travel in the opposite direction relative
to the arrow shown.
Procedure
1. Examine the IOM for damage, and closely inspect the interface connector. Do not install if the pins are
bent.
2. Grasp the IOM using both hands, and with the latch in the open position, orient the module and align it
for insertion into IOM slot 0.
3. Ensuring the IOM is oriented as shown in the illustrations, slide it into the enclosure as far as it will go.
An IOM that is only partially seated will prevent optimal performance of the enclosure. Verify that the
module is fully seated before continuing.
4. Set the module 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 mid-plane. Tighten the thumbscrew to secure the latch in place.
5. Reconnect the cables.

Module considerations during initialization.
Expansion module
If the storage system is configured with expansion enclosures, the replacement expansion module may
take up to one minute to initialize after the cables are connected. Verify that there are no illuminated Fault
LEDs on the enclosure front panel or the IOM faceplate.
