Environment

  • VIP-4060 primary/redundant pair with 1.11.5 or 1.11.6 firmware
  • VIP-4500 firmware rev 2012.12.0.13
  • Left / Right split display with external VIP-4400 sync generator.

Cause

  • VIP-4500 processors running older firmware may occasionally send V-Max frames with data that confuses the VIP-4060s and causes them to lock up.

Resolution

  • Update firmware on VIP-4500s to version 2015.03.0.00 (Note: This will disable the analog video inputs on the VIP4500)
  • Remove external sync generator source from the VIP 4500s and allow one processor to sync the other using method 1 shown in DD2069103.
