To replace a failed SFP transceiver, read "SFP Transceivers" on page 27, 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.
