Power Calculation
Got a power configuration question , hope someone can help.
In the datacenter, for a 42U cabinet, put in 20s poweredge 2950 server. Is L5 20 enough? I don't know anything about the power.
The cabinet has 2 power strips, it will be redundant. Not sure if L5 20 will handle it or it will overload, If not L5 20, what will be next one?
I tried the online Dell Energy Smart Solution Advisor but it doesn't have poweredge 2950 or older server for me to add it to the rack for calculation.

Hi mbworldz,
An L5 20A cable will support an amperage draw of 80% of its listing so 20A*.8 = 16A. If you assume that a loaded PE2950 draws 3A, then you can at most put 5 loaded PE2950 (3A*5= 15A) on that power strip before you overload it.
There are 30A power strips/PDUs but you'll have to check your data center to make sure that your power circuits can support 30A.
