Can't Access Layer 2 Switch Web Interface (AT-FS750/24POE)

I have an Allied AT-FS750/24POE. The switch has no reset button or RS232 port. Everything is configured through the web interface. Allied Telesys has lousy support. We recently virtualized our network and reconfigured our addressing. Our netmask used to be 255.0.0.0 and we changed it to 255.255.255.0. We forgot to update the ip configuratioon on the switch which has a static address. I can no longer access the web interface and I wonder if it has to do with the subnet mask.

Edit: I can ping the switch

Then I have a problem. Old scheme was 10.0.0.x 255.0.0.0. new scheme is 10.0.0.x 255.255.255.0
I connected a laptop and changed the ip config and got nothing. Advanced IP scanner pings it but doesn't detect a web manager
I meant do you remember it's old ip. I assume you do if you were initially going to change it in the first place. Can you get it's mac address somehow. Maybe you can then assign a static arp entry onto your laptop and access the switch then.
Honestly, doublecheck your ip configuration on your laptop. If you place your laptop ip configuration on the same subnet as the old ip of the switch and plug it into a port that is on the same vlan as the switches ip address, you should be able to connect to it.

Yeah, I know. It really didn't work. But thanks for confirming that I was doing the right thing.
I even double checked my ipconfig on the laptop and everything was right. I'll bet the web page is corrupt. Thing is, this switch has absolutely no other way to access the management. What a lousy design.
Were you able to ping the ip when you had your laptop configured. Are there multple vlans configured on the switch?
