6–54 SF7x Storage Enclosure FRU Replacement
WARNING—USE TWO PEOPLE.
Releasing the latch allows the inner assembly to be removed
from the extrusion tube for this operation. Be prepared to
take the weight of the inner assembly when it comes free of
the extrusion tube. Have an ESD-protected workspace ready
to put the inner assembly on after removing it.
10. Loosen the four captive screws in the corners of the enclosure frame
and push the inner assembly out of the enclosure until it engages the
latch.
11. Double-check the enclosure to verify that nothing can prevent the
inner assembly from being pulled out farther. Reach into the chassis
and release the latch. (It may be necessary to push the frame back in
about a quarter inch before the latch will release.) See Figure 6–11.
Push the inner assembly free of the extrusion tube, reach into the
inner assembly, grasp the sheet metal in front of the fan, and pull.
Set the inner assembly on an antistatic work surface.
12. Turn the inner assembly on the side exposing the OCP cable that
needs replacing.
13. Remove the acoustic panels necessary to replace the defective OCP
cable. Six Phillips screws hold each acoustic panel on the inner
assembly. If you are replacing a single OCP cable, remove only the
panel for the associated disk ISE (Figure 6–17).
14. Remove the OCP cable from the inner assembly and the disk ISE.
Note how the cable is routed.
