I have a Cisco Catalyst 4506 switch with a WS-X4516 Supervisor V engine that will not boot. Starts to boot the IOS and displays about 35 '#' symbols and locks up completely.  I've tried loading a different IOS via TFTP, but it behaves the same way.

Sounds like a bad sup.  Did you try connecting a PC to the console port during the boot process to see if there are any error messages?

I think we have it figured out -- bad DRAM module.  Swapped one from a working switch and it booted OK.
