Changing the Cisco 4948 Ethernet Switch Password
You can change the passwords for both serial port access and SSH access to the
switch.
There are two different methods to access the switch. One is through a serial port and
the other is through ssh. When using serial port access, there are no user accounts, so
the enable password is all that is required. When the switch is accessed via ssh,you
must supply a user account and password before you can change the password.
During the installation of the system, the admin user is created and you can use this
user to access the switch using ssh.
