CAUTION: To prevent degraded performance, do not twist, fold, pinch, or step on fibre optic
cables. Do not bend the fibre optic cables tighter than a 5 cm (2 inch) radius.
1. If possible, use the MD Storage Manager to create, save, and print a new storage array profile.
2. If the Recovery Guru directed you to replace a failed RAID controller module, go to step 3, else run
the Recovery Guru to identify the failed component.
3. Unpack the new SFP+ transceiver.
NOTE: Ensure that the SFP+ transceiver is replaced by the same type.
NOTE: Set the new SFP+ transceiver on a dry, level surface near the RAID controller module,
the RAID controller module enclosure, or the expansion enclosure.
NOTE: Save all the packing materials in case you need to return the SFP+ transceiver.
4. To locate a failed SFP+ transceiver, view the FC IN (host channel) speed LEDs on the front of the
RAID controller modules. If an SFP+ transceiver has failed, both FC IN speed LEDs for a particular
port are off.
• If both FC IN speed LEDs are off for a particular port with a known good cable, the SFP+
transceiver must be replaced. Go to step 6.
• If at least one FC IN speed LED is on for a particular port, the SFP+ transceiver is functional. The
FC IN speed LEDs indicate a channel speed of 4Gbps, 8Gbps, or 16Gbps. Ensure that the speed
indicated by the LEDs is what is expected.
WARNING: Data processing environments can contain equipment transmitting on system
links with laser modules that operate at greater than Class 1 power levels. Never look into the
end of an optical fiber cable or open receptacle.
CAUTION: To prevent degraded performance, do not twist, fold, pinch, or step on fiber optic
cables. Do not bend the fiber optic cables tighter than a 5 cm (2 inch) radius.
5. If present, disconnect the fiber optic cable from the failed SFP+ transceiver.
6. Remove the failed SFP+ transceiver from the interface port.

1. SFP transceiver
7. Install the new SFP+ transceiver into the interface port. Ensure that the transceiver is properly seated.
8. Reconnect the fiber optic cable.
9. View the FC IN speed LEDs and the Physical Disk Channel speed LEDs.
Based on the LED status, perform one of these actions:
