Question cant access webui Nortel Baystack 5520-24T-PWR

[bdydrp]

Hi,

up until recently i could access the web ui via its IP and everything was working fine, until i changed something (not even sure what i changed tbh) and now I can no longer access the web interface of my switch
From a windows cmd prompt, when i ping the IP i get a 'destination host unreachable'

Everything connected to the switch still works.....

Any advice on how to proceed?

Cheers

Reset and start again, the IP address is only for management (L3) the switch is still functioning at L2.

To factory restart i believe i need a serial cable (which i dont have) and use putty
This would also change the back to default IP, 192.168.192.168,
would the switch stil work at L2, if my lan is at 192.168.1.0/24?
