13. Place the mount plate on a work surface and disconnect the SCSI jumper cable, if installed, and either one
or two hot-swap drive cage management boards (terminators), which ever is applicable.
14. Locate and remove the eight Torx 15 screws, four per side, that are attaching the backplane to the mount
plate.
Installing the Hot Swap Drive Cage Backplane.
1. Install the new backplane to the mount plate by securing it with the eight Torx 15 screws.
2. To reinstall it in the chassis, align the mount plate into the metal rail and slide the mount plate into position,
making sure that all cables are out of the way. Secure the mount plate to the chassis with the blue
thumbscrew.
3. Reverse the steps listed above to reassemble the server.
Replacing the Fan Assembly
Replace the Fan Assembly when the system indicates slow or failing fans. The fans are contained in a single
replaceable module enclosed in the fan tray. The fan tray and the attached air scoop are removed to upgrade
system board parts, remove the system board, or access power and signal cables.
NOTE When installing the fan cage, be very careful to move all cables out of the way so they
don’t get pinched when sliding the fan cage in on the rails.
When installing the fan assembly, make sure the SCSI cable is not over the connector
where the fan assembly plugs in.
