It might also be helpful to ensure you have a battery backup that provides pure-sine wave electricity when plugged in, and ideally as close to it as possible when on battery backup and the power is out.
I ran a lot of gear through a decent separate PDU and the rack of datacenter gear refused to die. No burst transistors or other things that can be the norm after.
My comment was definitely based in this - providing the cleanest electricity possible, however, doesn't hurt, and can only help.
