I took down a 5300 that had been running for several years to move it 
out of the basement under our CO to the actual CO itself.  I hate doing 
that because that's when most hardware fails.  Once I had it reracked 
and cabled again I tried to power it on to no avail.  It would come on 
but would more or less sit there dumb as a post.  Ultimately I 
determined that the board with the 8x PRI interfaces had gone bad (I 
forget the 5300 terminology and LC names; my therapist has done a good 
job of repressing those memories).  New LCs couldn't be purchased any 
more.  Official refurbs weren't availble.  SmartNets could no longer be 
purchased either.

In the end I spent $34 and bought a 4x PRI replacement LC on eBay.  The 
5300 has been working ever since.  Our dialup numbers have dwindled so 
low since that box was maxxed out (2 5300s were maxed out at that POP 
back in the days) that no one even noticed the loss of modem capacity. 
I almost wish that the box had completely baked itself so I could 
justify killing off the service.  I dread getting a call about a dialup 
problem.  "You have dialup and you live in town?  Down the street from 
the CO?  #$%%^&*!!!!"
