10. Inspect the CM to make sure it is not damaged or bent in any way, paying particular attention to connector pins.
11. Properly orient the CM so you can grasp the handle, then orient it to its empty slot.
12. Slide the CM into its empty slot until you feel it fully connect to the midplane.
13. After pressing against it once more to make sure it is fully seated, close the latch until you hear a click as the latch
handle engages into the locked position.
14. Tighten the thumbscrew to secure the latch, then reconnect each of the cables to its labeled location, again making
sure all are fully seated.
15. Inspect all cables for any damage, especially the connectors. If you use passive copper cables, they cannot have any
connection to common ground earth.
16. Reconnect all cables you removed according to the way you labeled them.
17. If you are replacing both CMs, repeat the entire process for each of them.
18. Verify each CM fault LED is off.
19. Return to the front panel of the storage enclosure and verify that the Fault-Rear panel LED is not steady amber.
Replace a main bay cover
The main bay cover protects the main bay components and assists with containing airflow to cool the main bay.
You can still maintain continuous operation during the replacement of the main bay cover, as long as it is within the
time limit of eight (8) minutes, since the removal of the main bay cover impacts airflow in the main bay.
CAUTION If you remove any FRU while the storage enclosure is powered up, you must replace it with a known
good spare within the allotted time for that FRU. If you do not replace the FRU and, when applicable, close the related
cover within the identified time limit, you void the product warranty and the storage enclosure might overheat, causing
equipment failure and possible data loss.
To remove and replace the main bay cover:
1. Facing the front of the rack cabinet, loosen the storage enclosure chassis flanges by twisting the top captive
thumbscrew on each side of the storage enclosure to the left.
2. Lower the pull handles, then gently and steadily pull the storage enclosure out until it locks in the service position.
3. After locating the main bay cover's rear latch, closest to the rear panel, push down on the tab, then release it by
pressing the latch away from the rear panel and toward the hinge.
