Is this a new switch?
Everything set to factory defaults?
If so, then all the ports are in the 'default' VLAN
Below is a sample of how to get started
Connect to the switch via the console cable.
Log in
default username is "admin"
default password is blank
To configure an IP address on the default VLAN:
configure vlan default ipaddress 192.168.1.2/24
To configure your default gateway:
configure iproute add default 192.168.1.1
To set the admin password:
configure account admin
(then enter the new password twice)
Now, you should be able to connect you computer to the switch and telnet to 192.168.1.2 for remote access to the switch.
Hope this helps
