Looking For 8 To 9-Port POE Powered Switch

Hi

We are looking for a 8 to 9 -port POE switch. We need 8 PoE ports capable of at least 8 w each. Power budget to be 60 watts total. The switch itself must powered as a PD: It must get its power from an upstream PSE (Power Sourcing Equipment) and of course connected to this PSE via Ethernet Fast or Giga. No preference.

Industrial, DIN Rail mounted type preferred but not mandatory. Must be fan-less however. 

I have searched through google but the results are confusing. I am left to research each results individually. I think I better ask the collective here. :)

Thanks in advance

Thanks .. a step in the right direction. It has a fan and the 6 other non-PoE ports would go unused ... The fan is a deal breaker.

It would seem to me as an important market segment. They are far and few. THe NEtgear site in particular is not clear and the nomenclature is all over the place. They are sometimes called "pass-through" PoE  and in some companies extenders PoE... I am still confused. Counting on the collective experience and knowledge to sort through these...

Keep them coming people!

Why is the fan a deal breaker? As a last resort it could be disabled, of course you’d have to break the seal and void warranty, and risk killing the unit in time.

I don't think you will find a PD unit with that kind of power budget.

I would suggest ComNet, but don't think they have any PD switches.

Have you looked at "powered fiber" type switches and cables? Altronix, Commscope?

I don't think you're going to find such a product. I have seen 5 port switches that are PD powered, but even they have limited PoE PSE ports.

Hi

There are such products. Veracity is one but there are many others. The confusion stems from the nomenclature. Some companies call these PD powered some call them PoE pass-through switches.

In those search I came upon a company based in the USA. Tycon Systems. I hasten to say that I have NO experience with them , have never used their products but they have a breadth of products that could satisfy many needs and solve many pesky problems. They also have poE switches and other accessories that may solve my (and others') issues. I think I should share this with this helpful collective.

Their webstore (NO EXPERIENCE , just getting my feet wet with them. Explore and decide for yourselves).

Thanks to all!

You would need one juicy injector to power the unit plus all the downstream cameras.

PoE injector of 60 watts are rather plentiful. Several brands comes to mind there are many others. Work on the new standard 802b... ? PoE +++ is ongoing for up to 120 watts ... on Cat 6. ex

This one from Planet

This one from Axis

Tycon has those too

Tycon system has also a "Passive PoE" another name for their proprietary injector splitter for up to 72 watts on Cat 6 and up. In my expereince cameras aside from PTZ most cameras consume around 5 watts even with IR. Multi Imager will require more for sure although, I haven't seen 30 watts from those we have used. as they say YMMV but 8 IP cameras on a switch is around 50 watts max in our experience.

True, but you need more than 60 watts. 60 watts is just dedicated to the cameras. You need some extra power to power the switch as well.

Also, not sure if you are using this for the purpose of it being a long cable run or not, but if so, thats going to be another problem within itself. 8 watts at the power source dedicated per camera isnt going to be enough 

I think i have seen 90 watt injectors in my day, but even then i think you are still pushing it in this scenario.

I havent researched your Passive POE device but I dont think thats what you want in this scenario either. You need 802.3 POE

Let's look at it this way...

a 8-port PoE switch with a Power budget can be summarized with room like that:

8 cameras at 5 watts each... 40 watts

PoE switch at worst 10 Watts.

Loss on the line 10 watts (!!!!). 

60 watts covers it.

IFS (now Interlogix) has some beefy industrial-grade switches that can do PoE.  We have been running four of their 4-port switches and one media converter in "bake in the sun" conditions for about four years now without any failures.  I don't know if they can act as PDs.

Check out the D-Link DES-1005P 

Not the port count you're looking for, but in the right direction

Try as I have , I couldn't find out if it was PD powered. Is it in your experience? They have two firmware versions. Which one is PD-powered  or passthrough?

Thanks in advance

You maybe limited to 4-ports of POE... can you pull two cables?

Look at this guy if that is an option.
