RB112 With POE and Netgear POE Switch Doesnt work???

Hi,

I tried last night getting a RB112 via POE on a Netgear POE switch to work, but it simply doesnt power. Obviously I have changed the POE jumper, and it works fine with the Mikrotik POE adapter, but not a netgear POE switch.

Has anyone else had this problem?

What POE switches do people have them working with???

Hi,

Mikrotik didn't implemented the full 802.3af standard. They only support
powering over the spare pairs. AFAIK the Netgear and many other switches do only provide the power on the data pairs.

Have a look here:

http://forum.routerboard.com/viewtopic.php?t=2945

After some complains in the routerboard forum Mikrotik added the following sentence to the product description:

IEEE802.3af Power over Ethernet: 12V or 48V DC (except power over datalines) Power jack: 11..60V DC

Is Mikrotik selling 802.3af compliant PoE adapters? Or do you mean these 48V power supply?

mmm, that seems pretty inflexible to do it that way.

The POE injectors Mikrotik sell are: EBU-101-01 (search on the net)

The problem with these is you need 1 per device, and 1 power supply per device.

We just used 16 of these on a job and you can imagine the cables and power supplies required to do this, really made for a ridiculous solution!

Anyone know of a better solution?

Hi, I have the same problem that “hotspotsolution”. Looking the 3Com switches I see the 2226 PWR

and the 4400 PWR

Anyone hadve tested it on Mikrotik? or have any solution.

Best regards

Hi kiket,

we have the old version of that 3com 2226PWR Plus switch. Old version is without "Plus". That old version didn't even power our 3com PoE Accesspoints (the officeconnect b/g) :frowning:

The datasheet of the new one says that the power is on the spare pairs. So there should be a chance that it work.

Please post your results if you will test it.
