b. Detach the cable retention clip from both power cords.
c. Power down the enclosure by disconnecting both power cables, one from each PSU.
Step 3 : Disconnect the HD Mini-SAS cables from the rear of the enclosure by pulling (don't jerk) on the

Make sure each cable is labeled or label them yourself to ensure that they will be plugged back
into the same location.
