Hardware Installation
1. Turn your computer off and any peripherals connected to the computer (i.e.
Printers, external hard drives, etc.). Unplug the power cable from the rear of
the power supply on the back of the computer and disconnect all peripheral
devices.
2. Remove the cover from the computer case. Refer to documentation for
your computer system for details.
3. Locate an open PCI or PCI-X slot and remove the metal cover plate on the
rear of the computer case.
4. Insert the card into the open PCI or PCI-X slot and fasten the card’s bracket
to the rear of the case.
NOTE: If installing the card into a small form factor/low profile system,
replacing the pre-installed full profile bracket with the included low profile
installation bracket may be necessary. This configuration will require two
adjacent expansion card slots in the host computer system.
5. Place the cover back onto the computer case.
6. Insert the power cable into the socket on the power supply and reconnect
all other connectors removed in Step 1.
