    22Unlike the IP8800, This is a purely !OpenFlow switch, unable to do ''anything'' without a controller. The steps can be found documented elsewhere (ref. below), but we repeat the steps just in case things change.

     61== 3. Configuration ==
     62The Quanta is pretty much just a modified, minimal Linux box with a bunch of ports. Upon startup, you will be at the Linux shell as root.
     63 * eth0 and eth1 as given by `ifconfig -a` are eth1 and eth2 on the faceplate, respectively. The interfaces can be manipulated as with any Linux box using `ifconfig`.
     64 * The ssh server (dropbear) is enabled by default. Telnet can be started by invoking telnetd. In either case the default username is `root`, and password is `OpenFlow`.
     65
     66=== 3.1. Key files ===
     67 The !OpenFlow components of the switch rely on the following:
     68 * `/etc/rc.sh` - system startup script: bring up `lo`, mounts filesystems, loads kernel modules, ect
     69 * `/etc/system_config` - system initialization scrit
     70 * `/etc/system_config` - system configs unique to each switch
     71 * `/rc.soc`, `/etc/config.bcm` - starts !OpenFlow components
     72 * `/etc/find-env` - defines many of the system variables
