Can I use a ePMP Force 180 PoE with a HP ProCurve 2910al PoE Switch?
I have 33W per port available.
If it's an 802.3af/at standard PoE switch (which I'm assuming it is), no, it won't work. The reason being, that the Force 180 needs 30 volts, or less, and standard PoE is 48-56v.
The short answer is no!
However, if you really want/have to, then the following is useful.

Is it an Alt A/B issue...? Power is carried over the cabling using two techniques: Alternative A and Alternative B
Ethernet Interface 10/100/1000BaseT, Compatible with Cambium PoE pinouts (V+ = 7 & 8, Return = 4 & 5) and Standard PoE pinouts (V+ = 4 & 5, Return = 7 & 8)
Cambium - Alt B is 4/5 & 7/8 (spare pairs)
Our POE Device - Alt A is 1/2 & 3/6 (along with the ethernet data)
Specifications PoE 802.3af Type1 PoE 802.3at Type2
| Power at the PD | 12.95W | 25.5W |
| Maximum power using PSE | 15.4W | 34.2W |
| Voltage range(at PSE) | 44 to 57 | 50 to 57 |
| Voltage range(at PD) | 37 to 57 | 42.5 to 57 |
| Maximum Current | 350 mA | 600 mA |
| Maximum cable loop resistance | 20 Ohm with cat.3/Cat.5 or better | 12.5 Ohm with cat.5 or better |
Its wrong votage as well.
Force180 is 24v, standard poe is 48
so.. is passive PoE Device. EOT
