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

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.
