where you can see a previously installed Myrinet/PMC interface to the left of the circled
PMC connectors. 64-bit PMC slots or cards have three connectors, as shown. 32-bit
PMC slots or cards have just two connectors. It is alright to plug a 64-bit card (PMC64A,
PMC64B, or PMC64C) into a 32-bit slot, or a 32-bit card (PMC32A, PMC32B,
PMC32C) into a 64-bit slot, but in either case the card will function as a 32-bit interface.
Step 2: Insert the Myrinet/PCI interface into a PCI slot.
Case 1: Tower unit host
With a tower unit host, a PCI-short-card interface is installed vertically in a PCI slot. Any
of the PCI slots could be chosen for the installation of the Myrinet/PCI interface.
However, for best performance, a 64-bit interface should be installed in a 64-bit PCI slot.
Inasmuch as some PCI connectors are more close-fitting than others, you may need to
push quite hard on the front panel and the edge of the card to seat the card securely.
