Replacing an IOM 89
2. Insert the drive carrier module into the enclosure. Make sure that the drive is held vertically with carrier latch
positioned at the top, and the carrier hinge is present at the back of the enclosure as shown in
Figure 73 .

3. Slide the drive carrier fully into the DISC slot within the enclosure.
4. Continue to push the DDIC (drive) firmly until the handle fully engages. The camming foot on the carrier will engage
into a slot in the enclosure. You should hear a click as the latch handle engages and holds the handle closed.
5. Verify that the amber Fault LED on the DISC module handle is off. Verify that the front panel LED states show no
amber module faults. The enclosure front panel Drive Activity LED will blink green to show DISC activity.
Replacing an IOM
IMPORTANT: If the Exos E 4U106 enclosure is configured with a single expansion module, it must be installed in IOM slot
No.0. As you face the enclosure rear panel, this is the IOM slot located on the right. An IOM blank must be installed in the
adjacent slot (No.1) as shown in
Figure 4 (page 17) . This configuration is required to ensure sufficient air flow through the
enclosure during operation.
The IOM replacement procedure is solution-specific and depends on system configuration and software implementation
(including SAS zoning as well as multi-path and failover/failback procedures). Consult your solution service
documentation for details on pre and post IOM replacement procedures to minimize system disruption during
replacement activities.
You may need to replace an IOM when:
• The Fault LED is illuminated
• Logs or events in the firmware indicate a problem with the module
• Troubleshooting indicates a problem with the module
Before you begin
Removing a controller or IOM from an operational enclosure significantly changes air flow within the enclosure. Openings
must be populated for the enclosure to cool properly. Leave modules in the enclosure until ready to install a replacement.
If replacing both IOMs in a dual-canister enclosure, record configuration settings before installing the new controller
modules. See
“Removing an IOM” (page 90) , and “Installing an IOM” (page 92) for instructions about installing an
additional controller module.
