Product specifications

Attach one end of the PCI Expansion Cable to the Host Interface Card
and secure it using the captive thumbscrews on the cable. Carefully
route the cable to the PCI Expansion Interface Card (or Motherboard)
and secure it with the captive thumbscrews. It is important that the cable
be attached securely to the card connectors at either end.
MAGMA 64-bit expansion systems (such as the P7R64) include (2) PCI
expansion cables. Colored indicator labels have been provided on the
expansion chassis and the Host Interface Card, to assist the user in
completing the cable connection correctly. The first cable installed
should connect to those connectors with the teal labels; the second
cable should connect to those connectors with purple labels. Thus,
when properly installed, each cable will have matching labels at both
ends (teal with teal, purple with purple).
Step Eight: Recheck Installation
Check your installation before powering up the PCI Expansion System
for the first time. Although the power supply has an over voltage
protection device built into it, it may not "trip" in time to fully protect a
device that has been improperly connected or whose power cable has
been damaged.
Step Nine: Power Sequence
NOTE
If at all possible, plug the power cords from the PCI Expansion System
and your host computer into a shared power strip, preferably one tha
t
has surge and noise suppression circuitry built into it.
NOTE
The ‘Quiet’ 275 watt and the 300 and 400-watt power supplies are auto
switching, which means the power supply will automatically adjust to
the voltage required for the region you are in.
Powering Up:
You must apply power to the PCI Expansion System first and then
power up your host computer. This will allow the higher numbered PCI
buses in your hierarchy to be at a stable state at the time that the host
system issues its master power-on bus reset. In systems that perform
automatic PCI bus configuration, this will allow the configuration code to
recognize the PCI bus hierarchy and the attached devices.
If you have several PCI Expansion Systems in your configuration, you
should power up the most "downstream" expansion system first, then
