The POE power seems limited by the power module. If I feed it with (say) a 48vdc, 3A power source, can I get 120watts from the POE outputs?

The power is not limited by the source. It is limited by the output of the switch. It is a smart switch, so power can be regulated through the settings. You will not increase the power by using a larger power supply, and will in fact damage the switch.

hi, could be due to problems of energy. Check the feed if using PoE , could have a poor voltage. My happened to me something!

No. These cable assemblies are designed to be used with the power supply for the device you want to power. POE power is 48 volts and requires that the device you are trying to power can take the 48 volts and convert it to what it needs. The power from the device power supply is simply injected into the ethernet cable at the source end then extracted at the other end.

Does not accept the standard POE, you need to use a passive POE injector (like this: http://amzn.com/B00DZLSRJC)

Yes you need to have a POE device, you don't have to buy a new router/switch though. You can buy an injector such as this one http://amzn.com/B001PS9E5I. I did a measurement on the load of this device and with everything hooked up it draws about 4.5 watts and with the LEDs enabled it bumps up to 5.5 watts. This is your best low cost choice. If you want, there is also a barrel power connector pig tailed onto the camera. But it doesn't come with a power supply and I don't really know what the power requirements are. You would have to buy the power supply after finding one that works.

There is a CAT5 connection and a 12v power connection. The CAT5 is PoE capable.

You have 370 watts total for the switch in any combination of PoE and PoE+ that you want. Also, the 24 Port switches have the same 370 Watts as the 48 Port switches. I did one 48 and one 24 in our network. These are GREAT switches and the price is right.

I hate to have to disagree with the other responders, but I have found that cables do matter for POE. My application was a relatively high power one that pushed POE right to the limit, and I could only get it to work with a solid wire cable. The problem is that some patch cables, in order to maximize flexibility and minimize cost, use wire that's basically copper foil wound around a piece of thread. These just don't have the necessary current carrying capacity, at least not in my experience. A proper stranded wire cable would probably work, but I haven't tried that.

Also, don't forget, you'll need either a PoE switch (providing the 48V for your device(s)) or a PoE injector for *each* device.

I'm not using POE on my switch and it shows consumed power at zero percent, It would stand to reason that if your not using any POE devices its not going to use any power for POE, I don't see any settings to turn it off, the unit itself pulls 1.25 amps max.

There are adapters (power injectors) you can purchase that lets you send the power over the Ethernet cable. The adapters go on both ends of the Ethernet cable. However, most POE switches will not recognize it as a POE device. Therefore, it won't send the required voltage out to power the device , you still have to use the power adapter that comes with the camera. This is good so you don't have to have a power source close to the camera.

It comes with a simple proprietary PoE injector which you must use. It can't be powered by standard 802.3af/802.3at PoE switches or injectors, nor does it have a power input jack directly on the device.This product's simple proprietary PoE implementation is limited in range: It doesn't support full 100 m (300 ft) Ethernet twisted pair cable runs, after about 25 m the voltage drop is enough to cause random reboots when using maximum transmission power. This fact isn't mentioned in the manual.

No, it's simply a POE injector so you'll need a non POE switch to go with it. The idea for this is those who already have a switch but it's not POE can simply insert this In between and power a device.

I dont think so. The items just connect the power dongles to the un-used wires in the Cat5 bundle. POE transmits at 48 volts, while your non poe routers will expect something like... 5-12V. You'd need a buck-down power converter that can handle 48 to the voltage of your non poe router.

Yes, you are going to have to use either POE adapter or purchase a separate power cord

Almost - it has 48 rj45 ports, all have PoE - the first 8 are high powered, but higher-power is probably not what you want this for unless you only have a couple devices, the total power for all ports is 380Watts. The "uplink" ports are SFP slots, not usable unless you get SFP Gbics (fiber) (or copper modules if you really want that) - they are NOT SFP+. so limited to 1Gbps per SFP.

Yes it comes with a 12V AC adapter but not a POE injector. You can use it with this AC adapter in a location where you have an electrical connection available otherwise you will need a POE injector to get current to the remote location
