[c-nsp] Odd APS error.

[Lamar Owen]

i just replaced a failing 7401ASR with a 7507 with RSP8's on an APS-protected 
OC3.  The protect is a 7401ASR, and both are running 12.4 mainline.

The 7507 is the working, and traffic is passing, but I get an odd message when I 
issue show aps:
POS0/0/0 APS Group 2: working channel 1 (Active -linecard down)
        SONET framing; SONET APS signalling by default
        Protect at 10.250.2.252

Googling or searching on cisco.com for '-linecard down' doesn't enlighten me.  
Anyone seen this before?

sh inv on the 7507 shows this for the OC3 hardware:

Is this something coming from the ADM?
