NOTE: Equip yourself with antistatic protection and a replacement small form-factor pluggable (SFP
+) transceiver before replacing an SFP+ transceiver in the RAID controller module. Also, see the
initial setup information for the enclosure to verify LED definitions.
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.
