2 ups 750c units report no communication

[twilliams]

2 units worked when I installed them. few weeks go by and they moved to comms lost. Factory reset one, no go, removed from the site and readded, no go. I can verify its getting an IP address from DHCP. I can ping the device. But still reports no communication. Please help. I can be reached at twilliams@morepowertech.com or 1-888-556-8049 ext 102.
