1 Node-level switch IP addresses range from 172.20.66.1 to 172.20.66.4.
2 Top-level switch IP addresses start at 172.20.66.5.
Follow this procedure to configure network access to the Myrinet switch monitoring line cards:
1. Begin this procedure as the root user on the head node.
2. Ensure that an Ethernet cable from the monitoring line card primary Ethernet port is connected to an
Ethernet port on the Root Administration Switch. This connection is described in the HP XC Hardware
Preparation Guide.
3. Obtain the line card MAC address from the label on the front or back panel of the Myrinet switch.
4. Use the text editor of your choice to open the /etc/dhcpd.conf file, and add the following lines
inside the configuration block that begins with the text shared-network XC {. Enter the MAC
address obtained in step 3, and use the number zero (0), not the letter O, in the host name MR0N00.
host MR0N00 {
hardware ethernet your_MAC_address;
option host-name "MR0N00";
fixed-address 172.20.66.1;
}
In the following example, the entry is added to the end of the shared-network XC { block:
