Installing the 8-Port PCI ACC Multiplexer

The three major steps to installing the 8-Port PCI ACC Multiplexer are:




	CAUTION: The interface cables should be secured to prevent strain to the I/O card connector and panel connectors. The cables are heavy and apply significant force on the connectors. Use appropriate cable management to relieve strain on the connectors.

Install the MUX Card into the HP e3000 Computer

Notify users of a shutdown and shut down the computer.
Turn off power switch and remove electrical power to the system.
Plug the printed circuit card into an available PCI slot, following the instructions for that HP e3000 computer (e.g., an "N" class server).




	CAUTION: Be sure to observe the anti-static precautions while handling and installing the MUX card.

Install the Interchange Panel(s)

Place the rack mounting plate into the computer rack, so that the large holes on the sides of the plate are aligned with holes on the computer rack channels, refer to Figure 2-1 “Rack Mounting Plate”.
Figure 2-1 Rack Mounting Plate
Attach the plate to the rack using appropriately-sized machine-metal screws for your rack.
Place one interchange panel against the back plane of the mounting plate. Mount it to the plate, using the M3x10 Torx screws provided with the plate.
To mount another interchange panel to this same plate, repeat the preceding step. Note that you can position the plate in a different direction from the first one, as shown in Figure 2-2 “Rack Mounting Plate In Use ”.

Connect the MUX to (one of) the Interchange Panel(s)




	CAUTION: Before connecting the MUX card cable to the interchange panel, be sure that the power to the computer is off. Otherwise, serious equipment damage may occur.

Connect one end of the supplied cable to the connector on the MUX card and the other end to the interchange panel.
Apply power and reboot the computer.
After power is applied, check the Self Test LED indicator at the bulkhead of the MUX card, refer to Figure 2-3 “MUX Card Bulkhead with Self Test Indicator”.
