Installing the Baseboard
To install the baseboard:
1. With the rear of the electronics bay closest to you and the baseboard oriented so that the I/O
connectors line up with the cutout in the back left of the chassis (Figure 16, above), lower the
right end of the baseboard into the electronics bay and slip the board edge into the slots of the
foam panel (Figure 16, B, above).
2. Lower the other end of the baseboard to the floor of the electronics bay and slide it toward the
back of the chassis until:
a. The I/O connectors fit all of the way into the I/O connector openings.
b. The six mounting holes (Figure 16, A, above) on the baseboard are aligned with their
corresponding threaded standoffs in the floor of the electronics bay.
3. Install the processor board mounting brackets and processor-side plastic overlay as follows:
a. Align the processor board mounting bracket for the center of the baseboard with the three
mounting holes. Insert a screw through each of the holes and partially thread the screws into
the standoffs.
b. Align the other mounting bracket along the edge of the board. Align the plastic overlay with
the bracket and the two plastic studs. Insert a screw through each of the holes in the overlay
and mounting bracket and partially thread the screws into the standoffs.
c. Adjust the board position as needed and tighten the six screws.
4. Install the plastic protective overlay covering the PCI area of the board as follows:
a. At the side of the electronics bay where the edge of the baseboard is inserted into the foam,
place the two slots in the overlay over the hooked tabs (Figure 15, C, on page 41).
b. Slide the overlay toward the rear of the chassis to hook the tabs in the slots.
c. Carefully fit the overlay around the baseboard connectors and down against the board.
d. Tighten the captive screw that holds the overlay in place.
5. Install the front retention mechanism for the PCI add-in cards on the front wall of the electronics
bay (Figure 15 on page 41).
6. Connect all internal cables to the baseboard.
7. Install the PCI add-in board curtains as follows:
a. At the back of the electronics bay, slide the end of a curtain with the locking tab into the
topmost square hole adjacent to any add-in board expansion slot.
b. At the front of the electronics bay, slide the tab at the other end of the curtain into the clip on
the corresponding retention mechanism.
8. Install all PCI add-in boards and attach any internal cables to the boards.
9. Install the fan assembly in the main server chassis.
10. Attach the external cables to the baseboard I/O ports.
Making Backup Copies of NVRAM information.
1. Set the EXPRESSBUILDER CD-ROM in the CD-ROM drive, and activate the
EXPRESSBUILDER.
2. When the EXPRESSBUILDER becomes active, activate the Offline Maintenance utility by
selecting "Tool" from the menu → "Offline Maintenance Utility" → " Manage System
Information.".
3. When the Offline Maintenance utility becomes active, select "Save" from the menu.
