4. Move the expansion cable to a port on the RAID enclosure with a known good link
status.
This step isolates the problem to the expansion cable or to the controller module’s
expansion port.
Is the expansion port status LED on?
■ Yes – You now know that the expansion cable is good. Return cable to the
original port. If the expansion port status LED remains off, you have isolated
the fault to the controller module’s expansion port. Replace the controller
module.
■ No – Proceed to the next step.
5. Move the expansion cable back to the original port on the controller enclosure.
6. Move the expansion cable on the drive enclosure to a known good expansion port
on the drive enclosure.
Is the expansion port status LED on?
■ Yes – You have isolated the problem to the drive enclosure’s port. Replace the
expansion module.
■ No – Proceed to Step 7.
7. Replace the cable with a known good cable, ensuring the cable is attached to the
original ports used by the previous cable.
Is the host link status LED on?
■ Yes – Replace the original cable. The fault has been isolated.
■ No – It is likely that the controller module needs to be replaced
