I have a customer who had a 5550 die and I put a loaner in while theirs was repaired. Everything worked fine until I reinstalled their 5550. It keeps losing communication and causing the system to go into Night 1. It doesn't stay down long, looks like 12 seconds or so based on the logs. I get "The set is out of service due to loss of communication" then 12 seconds later I see "The set has been returned to service."
Any ideas other than sending it back to repair?
