This stuff is all in the network training rack (The 12U flight case)

Basics

The serial console server (SC1) runs DHCP from it's Ethernet 0/0 port (Round the back of the rack). This is usually plugged straight into the Netgear FS108 so via that you can access SC1 over telnet like so:

$ telnet 192.168.0.1

and to access all the other devices over serial via SC1, bearing in mind that the CABLE_NUM is the console cable of the target device from the above table.

$ telnet 192.168.0.1 6032+CABLE_NUM

SC1 Serial Config

Enable the elevated privileges mode. Enter the password when prompted. (The # following the hostname indicates that privileged mode is enabled)

sc>enable
Password:
sc#

You can check the current serial config with

sc#show line

Enter configuration mode. Hit enter when prompted by the Configure from terminal, memory, or network [terminal]? line.

sc#configure
Configuring from terminal, memory, or network [terminal]? 
Enter configuration commands, one per line.  End with CNTL/Z.
sc(config)#

Type the following to configure a line. The Async card runs TTYs on lines 33 - 64, with like 33 being the 1st console cable from the hardware table. Use ? to check the other config details. (33 to 35 is an example - this will config lines 33, 34 & 35)

sc(config)#line tty 33 35
sc(config-line)#

Some of the more useful commands are rxspeed & txspeed to set the baud rates of the cables you selected.
