SF3x Storage Enclosure FRU Replacement 5–37
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. 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.) 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.
11. Remove the fan assembly, using the procedures in Section 5.4.
12. Remove the fan mounting plate (PN 74-44306-01) by removing the
four countersunk screws inside the assembly.
13. Disconnect the internal DSSI cable(s) that you are replacing from the
front or rear backplanes.
14. Remove the screws holding the DSSI cable connector(s) in the cable
tray.
15. If you are installing a single DSSI cable, remove the tape holding the
bundled DSSI cables together.
16. Install the replacement cable(s) in the cable tray.
17. Attach the cable(s) to the connectors on the front and rear backplanes.
