Configuring In
terconnect Switch Line
Monitoring Cards
Configuring the Qu adrics switch controller cards, the InfiniBand switch controller cards, and
the Myrinet monitoring lin e cards on the system interconnect is required for diagnosing and
debugging problems with the system interconnect.
Yo u must configure these cards just before running the cluster_config command.
The f ollow ing procedures are documented in this appendix; do one of the following:
• Configure the Qu a dri c s switch controller card (S ecti on G.1)
• Configure the Myrin et switch monitoring line card (Section G.2 )
• Configure the InfiniBand switch controller card ( Section G.3)
_________________________ Note _________________________
You m ust reco nfigure the sw itch monitoring line cards any time you change your
system configuration and rerun the discover command.
G.1 Configuring the Quadrics Switch Controller Card
The Quadrics switch controller card provides access to Quadrics switch control functions
through an Ethernet connection . The controller card runs a process that collects configuration
and status information from t he switch.
Table G -1 provide
s the switch nam es and associated IP addresses you need for the configuration
procedure.

Follow this procedure to configure netw ork access to the Quadrics switch controller card:
1. Ensure that an Ethernet cable from the monitoring line card’s primary Ethernet port is
connected to an Ethernet port on the admin root switch. This connection is d escribed in
the HP XC System Softwa re H ardware Preparation Guide.
2. Connect to the switch c ontroller using either a VGA m on ito r and keybo ard, o r connect to
the serial port using a null m odem cable and a terminal or terminal emulation p rogram
