POE Query

[chris11256]

Hi,

 

I have a HP 2910al which is used to power 16 acccess points(IAP-315's) it's reporting 248w of power usage, this doesn't seem to correspond with the actual power usage of the access points.

 

Am I being thick or is there something funny going on with this switch?

 

In Comparison I have a 2930F with 21 access points connected only reporting 151w of usage.

What power class are the APs connected on the 2930 showing as?

 

For class 4 16 APs at 15.4w would be about the 247~

HI Steve,

 

The 2930 is reporting 21 access points as class 4

Never mind, rather embarrasingly I've fixed my own problem. The 2910 was set to allocate POE by class. Have changed it to allocate by usage and total used power has dropped to 100 watts.

That's an interesting one! I'll have to double check me HP switches methinks!
