Freescale CodeWarrior Gigabit TAP problem

We have a failure on a Gigabit TAP. When trying to connect to a P4080 target, we see the message:

CCSProtocolPlugin : CCS: Network timeout

 

For this TAP, the network timeout also occurs when running 'source IDcode.tcl' from the CCS. It is possible to ping the TAP and to connect over telnet, and the CCS was able to reprogram the TAP firmware successfully (which didn't fix it, by the way, or I wouldn't be posting this). Multiple other TAPs configured with the same static network settings (plugged in at different times, of course) can connect to the target board successfully.

 

The connection being tested (though this probably isn't important) is a JTAG connection using the COP/JTAG adapter. The adapter itself was tested on another Gigabit TAP and worked fine.
