[j-nsp] CFEB not coming online

[Eric Van Tol]

Hello,
I'm trying to replace a normal CFEB in an M7i with a spare CFEB that has an Adaptive Services Module installed on it.  The new CFEB isn't coming up and there don't appear to be any messages in the syslog as to what the problem is.  'show chassis hardware' shows the CFEB, but no serial number and here's the output of 'show chassis cfeb':

root# run show chassis cfeb 
CFEB status:
  State                                 Present   

[edit]
root#

I've tried doing 'request chassis cfeb online' and it doesn't do anything.  I'm pretty sure the CFEB worked, as it was pulled from another router.  I've also tried to reboot a few times and...nothing.  I've got 9.5R4.3 installed, FWIW.  Are there any special requirements when switching CFEBs in the M7i or changing from a normal CFEB to one with the ASM installed?
