WISP switch quiescent power consumption

Hello Forum,
Is there a quiescent power consumption table I can refer to for at least the WS-8-150-DC switch?

Thanks again!
Adam

Adam -

I did a quick search, and not finding anything, decided to get out the test equipment.

Powered by my bench supply, with no traffic load, 4 RJ45 ports linked, and 2 copper SFPs populated, my ammeter reads .14A(+/-) @ 49.1V.

0.14A * 49.1V = 6.874VA = 6.874W.

no SFPs and a single port linked reads .11A (+/-), resulting in 5.401W

So, we "say" to budget 8-10w, but your actual quiescent consumption is often lower, just depends on what's plugged in, and what what's plugged in is doing. hope that helps!
