5. Restart the DHCP service:
# service dhcpd restart
6. Use the text editor of your choice to open the /etc/hosts file to include an entry for each monitoring
line card, using the data in Table D-3 as a reference:
172.20.66.1 MR0N00
Make the entries above the following line in the file because any entries that follow this line will be
deleted if you reconfigure the system:
#XC-CLUSTER Do Not Edit Below this Line
7. Save your changes and exit the file.
8. Repeat this entire procedure for each monitoring line card, modifying the switch name and switch
address using the data in Table D-3 as a reference.
9. After you complete this procedure, you can start a Web browser and connect to the line card using
the IP address or assigned host name:
• http://172.20.66.1
• http://MR0N00
D.3 Configure InfiniBand Switch Controller Cards
The InfiniBand switch controller card provides access to InfiniBand switch control functions through an
Ethernet connection. The controller card runs a process that collects configuration and status information
from the switch.
Table D-4 provides the switch names and associated IP addresses you need during the configuration
procedure. Other switch naming conventions can be used depending on switch topology.
Important Note About HP Server Blades and Enclosures:
If the hardware configuration contains HP server blades and enclosures, the IP addresses for the switch
monitoring cards is based on the swBase address in the base_addrV2.ini file. Therefore, the IP addresses
shown in Table D-4 do not apply.
For more information about these IP addresses for HP server blades, see the HP XC Systems With HP Server
Blades and Enclosures HowTo, which is available at the following Web site:

Follow this procedure to configure network access to the InfiniBand switch controller card:
1. Ensure that an Ethernet cable from the monitoring line card's primary Ethernet port is connected to
the appropriate Ethernet port on the Root Administration Switch. This connection is described in the
HP XC Hardware Preparation Guide.
2. Connect to the switch controller by plugging a serial cable into the serial port on the switch and using
a terminal emulation program, such as HyperTerminal. You must use terminal settings of a baud rate
of 38400, 8 data bits, no parity, 1 stop bit and no flow control.
3. Press the Enter key to access the character cell interface to the switch.
4. Log in to the switch with the default user name and password:
