Reestablish IP connectivity from 2400 to Global Navigator

[gseale]

I have a NEAX2400IMX PBX that has an IP connection to a Cisco switch. I also have a Global Navigator that has a connection to the same Cisco switch. The Cisco switch has been replaced and the IP connectivity has not been resatblished between the PBX and the Global Navigator. I am able to ping both IP's.

I have performed a shutdown on the Global Navigator with no luck.

Do I have to perform an intialize on the PBX in order to reinstate the IP connectivity?

Thanks for any help!
