RE: i5 redundant power supply - needed?

Amen - We also configure everything with redundant power (i5s and 5094s)  Wish 
we could do the HMC's too, although the rack has dual power and it's not that 
hard to power down the HMC's and move the plug if we're planning UPS 
maintenance.  We have redundant HMC's and each HMC is on a different power 
supply.

I spent several hours getting an i5 back on line because a PS failed
while we were updating the FSP code. Murphy won that one because the
customer didn't have redundant power. (They do now!)  We configure
redundant power on every i5 we propose.
