PowerConnect 3548 - NO Connection to CLI

Hi,

i want to reset the 3548 to the factory defaults, because someone deleted the IP-configuration of the VLAN 1. So I can't connect to the switch by http. I connected via RS232 an Hyper-Terminal to the CLI. I see the output of the power-on self test but i can't send any command to the switch.

• Can I reach my goal without CLI?
• What can I do to reach the CLI?

Thank you for your help.
