Chapter 7 Base Switch Configuration
At this point, the OpenArchitect Ethernet Switch Blade should be installed and powered up for
the first time. This chapter helps you connect and configure the base switch by presenting
command line examples as well as a discussion of the example configuration scripts. You may
configure the fabric switch independently from the base switch.
Two switches, two consoles
There are two separate switches in the Ethernet Switch Blade. The base switch handles traffic
among base ports 0-23. These ports are reserved for control functions on the ATCA rack such as
connecting to IPMI (shelf managers), and connecting each node card to control and monitoring
devices.
Connecting to the Base Switch Console
You can connect to the switch console using a telnet connection or with a console cable. Use
the procedure below for a telnet connection. See Connecting to the Console Port, for
instructions.
• Connect an Ethernet cable to the host and the switch.
• Configure a host on the 10.0.0.0 network.
• The OpenArchitect switch is pre-configured with address 10.0.0.42. telnet to 10.0.0.42.
telnet 10.0.0.42

OpenArchitect Configuration Procedure
Switch configurations can be accomplished with a few simple commands. Once you’ve
configured your switch, the commands should be placed into a start up configuration script. Like
most Linux systems, the OpenArchitect switch boot process runs initialization commands and
scripts in
/etc/init.d/
. In particular, OpenArchitect runs
/etc/init.d/rcS
which in turn
executes all scripts located in
/etc/rcZ.d
starting with an uppercase “S” in alphabetical order.
Any configuration scripts you create should be named in the standard Linux/Unix manner,
starting with an uppercase “S” and numbered in the sequence you would like them executed. The
final step once the switch has been properly configured is to use the zsync command to save all
