We unfortunately have a customer with one of these boxes. Most horrible firewall UI I've ever seen!
It's not under maintenance, do Juniper require this to be able to get the latest firmware? I think this box is on 10x4R9.2 and if I am reading correctly, 12.1X46-D45 is the latest for it.
If I upgrade, is it a non destructive upgrade? (Obviously I need to backup config before).
