POE switch is not for everyone

This would be useful if you need to power up two IP cameras at a remote location that only has one cable going back to your server. Your main switch will need to have PoE too, to power up this switch. Don't forget to make sure you'll still be within the port power limit after hooking up the two cameras and switch.

You wouldn't typically get this as the main switch for your IP cameras as you need an existing PoE switch, and this only adds (splits) one extra PoE port.

Thanks eug for the explanation

$39 is a decent price I believe

  Only 2 PoE ports by the look, and there's this.

  ***NO EXTERNAL POWER ADAPTER: This product requires PoE input power (802.3af or 802.3at) to operate; it has no means to power from AC.

    Yep. POE Pass-through.

      so how is it powered

        By a POE Switch or Injector like Caff said

          @XeKToReX: Careful with an injector, a lot of them are passive and I wouldn't use passive poe through this unless it explicitly said it supported it.

    Yeah, 1 POE in, 2POE out, these are great if you need to 'split/share' 1 POE run

  But useful for those who use POE to power up IP cameras

    port power limit

    That's a perfect summary. Netgear call it "PoE budget".

    PoE standards vary wildly (Wiki).
    I can confirm this switch can be powered by either:
    PoE (802.3af) @ ~15w
    PoE+ (802.3at) @ ~30w

    Minus each GS105PE own consumption, this determines it's PoE budget.
    For example:

    • a PoE port can power 1 x GS105PE and maybe a PD device (depending on it's power draw).

    • a PoE+ port can power 1 x GS105PE and potentially 2 PD's (again depending on it's power draw).

    • or PoE+ port can power 1 x GS105PE daisy chained to another GS105PE powering 1 (or more) PD's.

  Also very useful as a managed switch if you need to manage VLAN's.

  You just need an existing POE switch.

  • 

    incipient on 16/06/2020 - 17:08

    I think this is unmanaged?

    • 

      redpen on 16/06/2020 - 17:44

      No, it's "Smart Managed Plus". See the GS105PE specs in this PDF: https://www.netgear.com/images/datasheet/switches/Gigabit_Et…

        Nice! Didn't see that and it's go jumbo frame support too.

  mcvic2k on 16/06/2020 - 21:09

  so if you have a CCTV NVR, this is PoE, and there is one cable going out to a CCTV Camera
  & you want to have TWO cctv cameras, using that same cable
  this is the device to buy ?

  so the 2 cctv cameras connects to this device, and one original cable goes back all the way to CCTV NVR ?

  • 

    eug on 16/06/2020 - 22:26

    Yes, as long as the PoE port on the NVR can supply enough power to run both cameras plus the switch. You'll have to check the specs on all your devices for that.

      @eug: i appreciate the help. thank you
