It is strongly recommended that the system be placed on its side, on a flat and stable surface. To avoid
potential breakage, the system front foot must not be resting on the surface.
Before performing the following procedure, read “Safety Notices” on page vii.
Removing the Disk Drive Backplane
To remove the disk drive backplane, do the following:
1. Place the system into the service position as described in “Placing the Model 275 into the Service and
Operating Position” on page 26.
2. Shut down the system as described in “Stopping the System” on page 25.
3. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the power source to the system has been completely disconnected.
4. Remove the service access cover as described in “Service Access Cover Removal” on page 28.
5. Remove the fan tray assembly as described in “Removing the Fan Tray Assembly” on page 35.
6. Before handling any card, board, or DIMM, be sure to use your electrostatic discharge strap to
minimize static-electric discharge. Refer to “Handling Static-Sensitive Devices” on page 24.
7. Disconnect the disk drive by placing the handle on the disk drive into the open position (perpendicular
to the drive) and pulling the hot-swap disk drive forward in, but not out of the bay. The lit LED on the
disk drive will turn off when the disk drive is removed. Pull and disk drive fillers forward in the bay.
8. Squeeze the blue latch tabs on the top edge of the disk drive backplane, and pull the backplane
upward to release it from the connector. Tip the disk drive backplane away from the chassis hooks on
the wall of the chassis, and lift the disk drive backplane out of the system.
