critical light on cisco router ASR 1001 x

Router was working fine but critical light on the front

Run:
sh facility-alarm status

However xcvr container 0/0/5 does not match up to gig0/0/5 as you might assume. I looked around the configured interfaces and found there was a port that was admin up but line down. It was a test port someone in IT had configured for their laptop.

Run
sh ip int br

Output:
GigabitEthernet0/0/0   x.x.x.x   YES NVRAM  up                    up    
GigabitEthernet0/0/1   y.y.y.y YES NVRAM  up                    up    
GigabitEthernet0/0/2   z.z.z.z      YES NVRAM  up                    up    
GigabitEthernet0/0/3   a.a.a.a     YES NVRAM   down down

We can see gig0/0/3 is the problem.

Fix
int gig0/0/3
shut

The critical light on the front went off. The problem was  we  had an interface configured and "no shut" but no cable plugged in.
