We are changing all IP address' for one of our locations. This includes the gateway 650 which has one CLAN, two medpro's and one IPSI. I am aware of how to change the CLAN and medpro's IP address', but I understand the IPSI is a bit "difficult". Getting a straight answer from my vendor has been a challend. They would like me to spend $2500+ to have them make the change after hours. I understand I need to connect directly to the gateway with my laptop and that is all I get out of my vendor. Any assistance on how I could accomplish this myself would be helpful.
