I recently had the shocker of installing a new card in my 6509 to find that it went into PwrDeny state. Taking a closer look via "show power" I saw the twin 2500W power supplies listed as actually pumping out less than half that power.
Question 1: Shouldn't a 2500W power supply provide 2500W of power?
Question 2: Where can I go to estimate the power needs of individual cards and the power provided by different supplies to avoid this in the future?
Hm. That's a step forward. I see here where it shows that a Sup720 (like we have) sucks down 315 watts. Though it doesn't say is that the system actually reserves double that power for it.
So far my google-fu has only turned up spec-sheets on power supplies 6000W and above. I see in those specs where all the power supplies output considerably lower wattage than they input, though at higher amperage. (More than meets the eye, it would seem.)
Thanks. I'd found that out peicemeal along the way. Had I read that early on, it would have saved me a lot of trouble. That, and the whole deal with the system reserving power for a redundant supervisor card that we will never install. Humbug.
