Failed SFP

What Caused the Problem?

A Small Form-factor Pluggable (SFP) transceiver on either the controller enclosure or the drive enclosure has failed, or is inserted incorrectly. If there is only one SFP failure, the storage subsystem is still operational. The Recovery Guru Details provides specific information you will need as you follow the recovery steps.

 Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.
