1. If needed, use the storage management software to create, save, and print a new
storage array profile.
2. Did the Recovery Guru direct you to replace a failed SFP transceiver?

3. Mute the alarm, and remove the back cover, if needed.
Caution – Electrostatic discharge damage to sensitive components. To prevent
electrostatic discharge damage to the module, use proper antistatic protection when
handling the module components.
4. Put on antistatic protection.
5. Unpack the new SFP transceiver. Verify that it is the same type of transceiver you
are replacing. Set the new SFP transceiver on a dry, level surface near the
command module. Save all packing materials in case you need to return the SFP
transceiver.
6. Check the Fault lights to locate the failed SFP transceiver. If a transceiver has a
fault, its light will be illuminated and amber.
