[j-nsp] 9.3 and M20 FPC

[Stacy W. Smith]

 From the 9.3 release notes:

"On M20 routers running JUNOS Release 9.3 and later, nonenhanced FPCs do
not come online because of memory limitations. These FPCs appear as  
FPC in
the Description column of the output from the show chassis hardware  
command.
As announced in Technical Bulletin PSN-2004-08-024, these FPCs have  
not been
supported since 31 December 2004. (To access the bulletin, log in at

[PR/291610]"
