• If the Bypass indicator is on, the GBIC may not have been inserted correctly.
Remove the GBIC and reinsert it.
• If the Bypass indicator stays on, or a Fault indicator on the environmental status
module comes on, refer to the storage management software (TPSSM7) for
problem determination.
Use the following procedure when instructed by the storage management software
(TPSSM7) to replace a failed environmental status module.
Before starting this procedure, read "Environmental Status Module" on page 81.
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
environmental card failure recovery procedures. Follow the steps given in the
software procedure before continuing with this procedure.
2. Unpack the new environmental status module.
Set the new 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 environmental status 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, use the kit instructions.
4. Locate the failed environmental status module (its Fault indicator should be on).
5. Remove the Fibre Channel cables from the GBICs in the failed canister, then remove
the GBICs (Figure 7-7). Label each cable to ensure that all cables are properly
reconnected to the new canister.
