4: Replacing Enclosure Components
Replacing a Failed RAID Controller Module
When TPSSM instructs you to replace a failed RAID controller module, read “RAID
Controllers” on page 17, and then follow these steps:
Caution: Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling enclosure components.
1. Check TPSSM for instructions on RAID controller module failure recovery
procedures. Follow any instructions provided before you proceed.
2. Unpack the new controller module. Set the new module on a dry, level surface near
the enclosure. Save all packing materials in case you need to return the controller.
3. Review all documentation shipped with the new RAID controller module for
updated replacement procedures and other information. If necessary, modify the
remaining steps to meet the system requirements. Kits often contain the most
current servicing information. If the kit instructions conflict with those in this
procedure, follow the kit instructions.
4. Locate the failed RAID controller module (its fault indicator should be on).
5. Disconnect the Fibre Channel cables from the SFP transceivers in the failed
controller module and then remove the SFP transceivers (see Figure 4-5). Label each
cable to ensure that all cables are properly reconnected to the new module.
Caution: Bending or damaging Fibre Channel cables can result in degraded
performance or data loss. Fibre Channel cables are fragile. Do not pinch the cables
with tie wraps, step on them, or bend at them at sharp angles.
6. Wearing antistatic protection, push down on the latch centered above the RAID
controller module. The levers will pop out of the locked position (see Figure 4-6).
7. Grasp the pull-rings and pull on the levers to remove the failed canister.
8. Wearing antistatic protection, slide the new RAID controller module all the way into
the empty slot.
9. Close both levers until the latch locks into place.
10. Install the SFP transceivers and Fibre Channel interface cables in their original
locations.
