Маршрутизатор MikroTik RouterBOARD RB1100AHx4

All power options support a wide voltage range of 24 – 57 V. However, you can not mix the voltages. If you’re using PoE-out to power other devices, the board will choose the source with the highest voltage (DC jack or the 2-pin connector) to power those.

Each PoE-out port can supply up to 25W of power. All the ports combined are limited to 130W, which should be enough for most setups. You can specify maximum available power from your power sources manually, if necessary. When it comes to PoE-out features, the new RB5009 can trade blows with our legendary PoE switches: CRS354 & CRS328. In the smallest possible form-factor and for the best price on the market!

Protect your uptime, protect your tranquility!

So what exactly happens if there is a problem with one of your power sources? Here’s a quick example: you have 24V on the DC jack, 48V on the 2-pin connector, and 57V on the PoE-in. The board itself gets powered by the highest voltage input – the PoE-in. If there’s a problem, RB5009 will fall back to the second highest voltage - the 2-pin connector. And if that fails – there’s the 24V option on the DC jack.

What about the PoE-out devices? Once again – the highest voltage wins. PoE-out devices will draw power from the 48V source on the 2-pin connector. If that fails – the 24V on the DC jack come into play. The board will always reserve 20 watts to power itself. If there is not enough power for all the PoE-out ports, it will start disabling the ones with the lowest priority. You can set the port priority manually.

This tiny form-factor shines anywhere: from confined research facilities and offices to huge corporate server rooms. And don’t forget that you can mount FOUR of these routers in a single 1U rackmount space

With the new RB5009, we want to empower all the small and medium ISPs that are always on the lookout for the most cost-effective and robust solutions. It is a perfect addition to our previous GPEN devices – a line of products designed to replace the expensive GPON solutions.
