TAC case already open.  Bad chassis...?  6509 with dual sup720 3a's, 
ws-x6748-ge-tx cards in mod's 4, 7, 8, 9.  Two weeks ago the mod in slot 4 
died with the error "power-bad".  Thinking the card died, we replaced with 
new.  Just today the new card dies the same death, moved it to slot 3, same 
result.  Booted switch, still dead card.

Some messages:
a fabric-sync error showed up right before the module died
sho mod 4 gets unknown card, for module-type and power-bad for status.
sho env all gets nothing showing up in slot 4, yet under Slot power 
requirements/usage slot 4 shows "Insufficient DC voltage levels detected on 
module 4"
on reboot:   %SYS-3-MOD_PWRFAIL:Module 4 failed to power up

Power to the device is data center power, doesn't get any cleaner as far as 
power.

Bad connectors on the backplane for power?
