• If the Power indicator is off, the canister may not be installed correctly. Remove
it and reinstall it.
• If the Fault indicator is on, or the Power indicator stays off, refer to the storage
management software (TPSSM7) for problem determination.
When instructed by the storage management software (TPSSM7), replace a failed GBIC
(Gigabit Interface Connector).
Before starting this procedure, read "GBIC Module" on page 83.
Caution: Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling drive enclosure components.
1. Check the storage management software (TPSSM7) for instructions on GBIC failure
recovery procedures. Follow the steps given in the software procedure before
continuing with this procedure.
2. Unpack the new GBIC.
Set the new GBIC on a dry, level surface near the drive enclosure. Save all packing
materials in case you need to return the GBIC.
3. Review all documentation shipped with the new GBIC 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. Locate the failed GBIC.
Important: When a GBIC fails, its Bypass indicator glows amber, and so does the
Bypass indicator of the GBIC to which it is connected (including the fault light on the
controller enclosure). Make sure you remove the correct GBIC. Use the fault lights
and the storage management software (TPSSM7) to locate the failed GBIC.
5. Wearing antistatic protection, remove the Fibre Channel cables from the failed GBIC
(Figure 7-6).
