[c-nsp] GBIC is missing

[andrew2 at one.net]

I'm convinced I'm missing something obvious here.  This shouldn't be
hard.  I'm trying to connect a pair of 7204 NPE-G1's with PA-GE's w/ SX
GBIC's.  I've inserted the PA-GE cards and inserted the GBIC's, but all
I get is:

sh cont gigabitethernet 2/0

Interface GigabitEthernet2/0(idb 0x50077080)
Hardware is WISEMAN 2.1, network connection mode is auto
  network link is down(NO CARRIER)
  loopback type is none
  startup time: 404 usec
  GBIC is missing

sh int gigabitEthernet 2/0

GigabitEthernet2/0 is up, line protocol is down 
  Hardware is WISEMAN, address is 0004.de7c.ec38 (bia 0004.de7c.ec38)
  Internet address is 209.173.128.21/30
  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, 
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full-duplex, 1000Mb/s, link type is autonegotiation, media type is
unknown 23
  output flow-control is unsupported, input flow-control is unsupported

I've tried several GBIC's and tried a spare PA-GE card and get the same
thing every time.  What am I missing?
