[cisco-voip] ethernet disconnected

[Mike Armstrong]

I've got a TAC case open on this (602611867).  7940 works OK on a 3524, 
won't work on a 3750.  I think it's power-related, since a debug interface 
shows absolutely no IP traffic.  The switch sees a powered device, offers 
power, and then the phone shows the "Ethernet disconnected" message.  It's 
peculiar to this phone; another of the identical hardware level (and 
firmware) works OK.
