I have a BCM50, Rls 2.0 with an expansion cabinet with a GATM8 in it. About every 3 months, I cannot access it remotely over the network. I move the patch cable to LAN port 3, and it works for a few months and then have to move it again. I have swapped ports on the switch, patch cables etc. The phones and trunks all stay up, it is just this that goes down.
