We also had problems with DTC flagging ports as bad on our 957's DTC72MX when
booting. Ports were not bad at all !
 
We got fed up with having to unplug fifty or so RJ-45's every time we
re-booted !
 
Solution:       HP replaced all DTC cards with newer ones which can be set NOT
                to perform test at boot-up. Problem fixed.
