Five-Volt Riser Board Installation
Dell now offers a Peripheral Component Interconnect (PCI) riser board for use with
customer-furnished five-volt (5V) PCI cards. Dell does not currently support any 5V PCI
cards installed in the Dell™ PowerEdge™ 1550 or PowerApp™ 120 systems. This 5V
riser board is furnished for the customer’s convenience.
These systems have one fixed expansion-card connector and one removable riser
board with a single expansion-card connector, which simplifies many installation pro-
cedures by allowing the user to remove the riser board and its installed expansion
card in a single step.
Expansion-Card and Riser-Board Removal
To remove the riser board and its installed expansion card, perform the following
steps.
NOTE: If the system is mounted high in the rack, you may find it easier to completely
remove the system from the rack before performing this procedure.
1. Shut down the system and turn off power to the system.
2. Disconnect the power cable from the back of the system chassis.
3. Loosen the front-panel thumbscrews securing the front panel to the rack and pull
the system chassis out of the top cover to its fully extended position.
4. Label and disconnect any cables connected to the expansion card through the
back-panel opening.
5. Release the expansion-card bracket by loosening the thumbscrew on the back
panel and rotating the latch away from the expansion-card bracket.

6. Lift the riser board up and away from the chassis (see Figure 1-1).
5V Riser Board Installation
Lower the 5V riser board into connector PCI2 on the system board, making sure that
the riser board is fully seated in the connector.
The 5V riser board contains a single 64-bit, 33-MHz PCI expansion-card connector.
NOTE: Connector PCI1 supports a single short 64-bit, 66-MHz expansion card in its
fixed socket on the system board.
Expansion-Card Installation
To install an expansion card on the 5V riser board, perform the following steps.
NOTICE: Full-length 5V PCI cards can be installed only in connector PCI2
via the 5V riser board. When a full-length card is in this connector, a
secondary microprocessor cannot occupy the PROCESSOR2 socket. A
terminator module must occupy the PROCESSOR2 socket.
NOTE: If the system is mounted high in the rack, you may find it easier to completely
remove the system from the rack before performing this procedure.
1. Shut down the system and turn off power to the system.
2. Disconnect the power cable from the back of the system chassis.

3. Loosen the front-panel thumbscrews securing the front panel to the rack and pull
the system chassis out of the top cover to its fully extended position.
4. Prepare the expansion card for installation.
See the documentation that came with the expansion card for information on
configuring the card, making internal connections, or otherwise customizing the
card for the system.
5. To install thecard, first alignthe metal mounting bracket with its slots on the back
panel and then insert the card-edge connector firmly into the connector on the 5V
riser board (see Figure 1-2).
Figure 1-2. Expansion-Card Installation
6. When the card is firmly seated in the connector and the card-mounting bracket is
aligned with the brackets on either side of it, close the expansion-card latch and
tighten the thumbscrew.
7. If the expansion card is a full-length card, secure the inner end of the card by
closing the plastic latch on the card guide over the top edge of the card.
8. Connect any cables that should be attached to the card.
See the documentation that came with the card for information about cable
connections.
9. Slide the system into the rack and the top cover, and then reconnect the system
and peripherals to their AC power sources and turn them on.
