Need help with PoE on a 5406zl

[PokerMunkee]

For some reason, I'm struggling with PoE power allocation on a couple of my 5406zls.  

I can go weeks without issues and then a few cameras will reboot due to not enough power, so the last ports which are lowest priority get shut off for a few seconds.  

I am using the first 4 blades (A-D) to power a bunch of PoE IP cameras that utilize around 2-4w.  I have 2x 120v PSUs installed.  The last two blades are used for DVRs., with PoE disabled on all the 48 ports (E-F).  

A "show power-over-ethernet" shows me I have 546W total and 305W remaining.  I have turned off redundancy.  I just need to power these 90 cameras and not worry about them starving for power.  

Right now I have each port using allocation by value.  I set each value to 7w.  So far I haven't seen anything drop but I'm not holding my breath.

What's the best way to setup my ProCurve 5406zl with my 2x273w PSUs so I don't have to worry about my cameras going offline?

Thanx.

Here is sh power brief and sh power-over-ethernet output.  Why does Module D only have 17w available?

You need more or better power supplies.

The one you have only has enough power to fully power up 3 modules.
