218 Cobalt Qube 3 User Manual
Adding a PCI expansion card
1. With the CPU riser board out of the system chassis, remove the screw
holding the PCI slot cover in place and remove the PCI slot cover. See
Figure 1 on page 2.
2. Install the PCI card into the PCI slot on the I/O board. Match the PCI card
alignment marks with the alignment guides on the slot. See Figure 107.
3. Fasten the PCI card in place with the screw that was holding the PCI slot
cover. Save the PCI slot cover, in case you want to remove the PCI card later.
Replacing the CPU riser board
1. Carefully slide the CPU riser board back into the system chassis (along with
the SCSI port if necessary).
2. If you had detached the external SCSI port from the back panel of the
Qube 3, slide it into its slot and re-attach it to the back panel.
3. Carefully slide the drive bay back into the system chassis.
4. Re-attach the drive bay to the chassis with the four screws.
✍
Note: Insert the CPU riser board with the DIMM modules next to
the front of the Qube 3; the expansion slot is oriented toward the
inside of the unit. Forcing the CPU riser board into the wrong slot
will damage the system and void your warranty.
