Every node in a cluster that uses a Myricom system interconnect has a PCI host
bus adapter (HBA), and each host interface has a connection to the interconnect.
This chapter presents the following information relating to the three versions of
the PCI card that might be used in an HP Cluster Platform solution:
General characteristics of the PCI card (Section 2.1)
A description of the single-port XP PCI Rev. D card (Section 2.2)
A description of the dual-port 2XP PCI Rev. E card (Section 2.3)
A description of the single-port 2XP PCI Rev. F card (Section 2.4)

2.1 General characteristics

The Myricom PCI card can have a single port (LANai XP), as shown in Figure 2-2,
or dual (LANai 2XP) port, as shown in Figure 2-3. Each has at least one
multiprotocol communication port, referred to as the X-port. (LANai is the Myrinet
terminology for its PCI-X interface processor.)
The faceplate of each PCI card has two LEDs. A green "link" LED illuminates
when the host is powered, the link is active, and the firmware is loaded on the host.
It blinks to show when packet traffic is flowing through the port. A yellow LED is
controlled by the RISC processor. It pulses when there is packet-sending activity.
The LED on each switch port indicates the state of that port. Green indicates the
port is powered, and a link is connected. Yellow indicates a fault. If the switch port
is unlit, the switch is not powered, or there is a problem with the line card. The
LEDs for the ports only light when there is a cable attached and the GM message
passing system from Myrinet is running. For more information about GM, see your
system software documentation and the following Myricom Web site:

A label similar to that shown in Figure 2-1 appears on every PCI interface. This
label contains the product code, the serial number, and the Ethernet MAC address.
