What I am looking at is a sup720 that consistently failed upon booting 
sxh or 15.1 but not sxd.

It would boot the sp, boot the rp, the rp would come up mostly and then 
crash, and you would be stuck at rp rommon.

Also, diagnostics failed on the fabric snake.

That sup is going back but the question remains. Is remote power switch 
a want or a need?
