MTP #2 has been pulled back out of the gang connector face and is stowed =
in the shell with the spares.
The spring push needs to be replaced.  While not broken, the tabs that =
lock it all together are now rounded over enough that it won't stay =
locked under the force of the mating connector's spring.
Fibers 31-60 will be missing until we can get it repaired.
