To change the password 

conf term
en secret <insert pass>
end
copy running-config startup-config

conf term
en password <insert pass>
end
copy running-config startup-config

why there are 2 passwords (secret and enable) is a mystery.

To turn off the password:
conf term
no en secret / no en password
end
copy running-config startup-config

Configuring a range of interfaces

VLAN configuration - what are trunk ports etc


Cluster Management Suite (CMS)

Getting started with CMS

Connecting to CMS

One of the FastEthernet ports needs to have an IP address, a computer can then connect directly to that port and browse to the set IP (192.168.0.100) and log in using the 'Admin' user. The web browser needs to be IE, and the Java must be JRE 1.4.0 media:j2re-1_4_0-win.exe. The only way to get the browser to use this version of the Java web plugin is to uninstall all other versions of Java!
