Setting up the Quanta LG4B

Unlike 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.

1. Preparation

1.1 References

• main site: ​http://openflowswitch.org/wk/index.php/LB4GImageSetup

1.2 Prerequisites

• OS on PC: Ubuntu
• packages on PC: ckermit, xinetd, tftpd-hpa

2. Installation

2.1 Connecting to the switch

A serial connection can be set up between the switch and a machine using a RJ-45 to RS-232 cable. Surprisingly, a Cisco cable will work for this. Connect the RJ-45 end to the port labeled "Con" on the switch, and the other end to the PC. Next, start a session from a shell with kermit as root:

kermit -l /dev/ttys0 
set carrier-watch off
set baud 115200
connect

Fire up the switch. If you see the U-Boot banner, you can stop the boot process so you can copy/burn the images onto flash.
