IIRC, the 3 power supplies are each capable of handling 1/2 of the load; you have a 3/2 power supply. The theory is that you can lose any one of the three and still run with no problems. The logic is that a power supply for 1/2 the load is cheaper than one that can handle the full load; and providing an extra 1/2 is cheaper than providing two full-sized power supplies. --Paul E Musselman PaulMmn@ix.netcom.nospam.com >Ian wrote (in part): > >Quick Note FYI. > >Had a power supply go the other day on our 820 V4R5. >No Probs - its got 3, so 2 spare - 99.999 uptime eh. > >Not quite.
