Hi Jonas,
First thanks for replying. As I mentioned in my previous msg I only have one PEM installed per firewall. PEM 1 is not present because it is not present at all, hense the red alarm. Please see below. I am starting to believe I may need to upgrade from [15.1X49-D80.4 to latest recommended Junos but not sure if that will clear the false alarm. Thanks:
