When you change out the ip cards out in the system is there any additional progrmaning, if the system currently has a ip card in it?

Depends if you are upgrading to the new IP card that just was released. I am pretty sure there is a procedure for it after going to the presentation. I would call necam support.

On older version, I always double check on 84 26 making sure that DSP have enough IP address , RTP RTCP, specially when changing from PZ64 to 128

If your talking about changing out an IPLA card or upgrading to a larger one we have found that the MAC address of the current IPLA gets locked into the router and they usually the router has to have a reboot to clear the MAC table..
