Installed NIC in a PCI-X slot

Case 2: Rack-mounted host

If the rack-mounted host is a 2U or larger, the low-profile PCI-short-card

Myrinet/PCI-X NIC with low-profile PCI faceplate may not require a riser card

for installation. If at all possible, avoid the use of a riser card. If you must use a

riser card and the riser card has multiple slots, insert the Myrinet/PCI-X NIC into

the riser card slot closest to the PCI-X slot on the mother board.

We recommend the PCI-X slot closest to the PCI chipset for the installation of the

Myrinet/PCI-X NIC. For best performance, the Myrinet/PCI-X NIC should be

inserted into a PCI-X slot that runs at maximum speed (133MHz) and should not

share the PCI bus with another PCI device. Note that some vendors ship their

mother boards with the speed of the PCI-X slots reduced, and you must manually

adjust the jumper next to the PCI-X slots to run at full speed. (In the following

pictures, the jumper is blue and located on the left side of the PCI slots.) Refer to

the hardware specifications of the mother board for details of the PCI slots.
