8. Rotate (lift) the air deflector out of the way. It is easier to access the cable if you lift the back plate
out of the way. You do not need to remove either SATA disk cable.
9. Remove the operator-information panel cable assembly from the retention-clip next to the air
deflector, but leave the power-supply cable in the retention-clip.
10. A tie-wrap holds the cable assembly to the mounting bracket for the rightmost fan (when viewed
from the front of the node and ignoring the fan on the power supply). Cut this tie-wrap to release
the cable assembly.
11. Carefully extract the cable assembly from the node. To do this, you must displace other cables;
particularly, the optical drive cables, power-supply cables, and the SATA cables. Minimize disruption
to these cables as much as possible.
