7: Drive Enclosure Component Replacement Procedures
!

1. Check the storage management software (TPSSM7) for instructions on fan canister
failure recovery procedures. Follow the steps given in the software procedure
before continuing with this procedure.
2. Unpack the new fan canister.
Set the new fan canister on a dry, level surface near the drive enclosure. Save all
packing materials in case you need to return the canister.
3. Review all documentation shipped with the new fan canister 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, use the kit
instructions.
4. If the storage management software (TPSSM7) instructs you to do so, turn off the
power to the drive enclosure. Otherwise, leave the power on.
Caution: To prevent the drive enclosure from overheating while in use, complete the
fan canister replacement procedure within 15 minutes from the time you remove the
failed fan canister to the time you install the new fan canister. Both fan canisters must
be installed in the drive enclosure to provide sufficient air circulation within the
enclosure.
5. Locate the failed fan canister (its Fault light should be on).
6. Wearing antistatic protection, slide the latch to unlock the canister (Figure 7-2). The
latch is at the bottom of the left-side fan canister, and at the top of the right-side fan
canister.
