a. Lift the spring-loaded blue retention pin away from the front of the backplane, then slide the backplane upward.
b. When the backplane cannot slide upward any farther, pull the backplane toward the back of the system to remove it from the retention hooks.
11. If applicable, remove the daughter card from the SCSI backplane. See Figure 1 -2 for the location of the daughter card connector on the SCSI backplane.
Installing a SCSI Backplane Board
1. If applicable, install the daughter card on the new backplane.
2. Install the new backplane:
a. Lower the backplane into the system and carefully feed the control cable through the opening in the backplane.
Ensure that any other cables will not interfere or be damaged when installing the new backplane.
b. Align the backplane with the retention hooks on the chassis, then fit the backplane over the retention hooks.
c. Slide the backplane downward until the blue retention pin snaps into place.
3. Connect the control panel cable to the control panel connector on the SCSI backplane. See Figure 1 -2 .
To prevent disconnecting the cable from the control panel, deflect the end of the cable to connect it; do not pull on the cable itself.
4. If applicable, reconnect the 1x2 backplane power cable to the SCSI backplane. See Figure 1 -2 .
5. Reconnect the SCSI data cable(s) to the backplane, being very careful to install them in their original locations.
6. Return the drive tray to the operating position.
a. While grasping both sides of the front panel, slide the drive tray toward the system board until it meets resistance.
Ensure that cables are not trapped or damaged as you move the drive tray.
b. Rotate the drive tray release lever toward the back of the system.
c. Using a #2 Phillips screwdriver, tighten the captive screw that secures the drive tray release lever to the chassis.
7. Reinstall the SCSI hard drives in their original locations.
8. Replace the diskette/optical drive carrier.
9. Reinstall the cover.
10. If you removed the feet from a tower system, reinstall them now and place the system in an upright position.
11. Reconnect the system to the peripherals and electrical outlet, and turn on the system.
12. If applicable, reattach the bezel.
Control Panel Assembly
Removing the Control Panel Assembly
1. If applicable, remove the bezel.
2. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet and peripherals.
3. If the system is a rack system located low enough in the rack to prevent access to the underside of the system chassis, remove the system from the
rack and place it on a work surface.
See " Removing the System From the Rack ."
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See
your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
