I have acquired an Enterasys VH-2402S switch. I am unable to communicate with it using console management port via puTTy (black screen/no response) or any other method. I had no idea of the IP configured in this switch. After some thought, since I acquired this switch from a network guy, who also did not know the IP, suggested I try a range of IPs in the 172.22.xx.xx range since it came from his company. Using AdvanceIP Scanner I was able to determine the configured IP address of the switch is 172.22.xx.255. Wow. This is an invalid IP I'm sure, and is preventing me access to it via CLI / ethernet cable. How do I gain access to this switch? I asked that network guy and just got a shrug and statement that I probably can't. It's almost like he knew it and wasn't bothering with it... Anyway, any ideas on how I can get access to this switch to change the IP to make the switch useful? Thnks!
