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 RecoveryGuru 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 RAIDcontroller 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 controllermodules. 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 bereplaced. 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 speedLEDs indicate a channel speed of 2 Gbps, 4 Gbps, or 8 Gbps. Ensure that the speed indicated by the LEDs iswhat is expected.Troubleshooting External Connections• Verify that the cables are connected to the correct ports before troubleshooting any external devices.
