4: Replacing Enclosure Components
Replacing a Failed SFP Transceiver
To replace a failed SFP transceiver, read “SFP Transceivers” on page 25, 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 SFP failure recovery procedures. Follow any
instructions provided before you proceed.
2. Unpack the new SFP transceiver. Set it on a dry, level surface near the enclosure.
Save all packing materials in case you need to return the SFP transceiver.
3. Review all documentation shipped with the new SFP transceiver 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 SFP transceiver.
Important: When an SFP transceiver fails, its bypass indicator glows amber, and so
does the bypass indicator of the module to which it is connected (including the fault
light on the controller enclosure). Make sure you remove the correct SFP transceiver.
Use the fault lights and TPSSM to locate the failed SFP transceiver.
5. Wearing antistatic protection, remove the Fibre Channel cables from the failed SFP
transceiver (see Figure 4-5).
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 sharp angles.
