Маршрутизатор MikroTik RB5009UPr+S+IN Router 1GB RAM 7x Gigabit PoE Out 1x 2.5GbE 1x SFP+ — продавец №5000902

It’s all about the power... This version of the RB5009 has all the bells and whistles of the previous model: Gigabit Ethernet, 2.5 Gigabit Ethernet, and a 10 Gigabit SFP+ cage for fiber connectivity. It has the speed, the power, and the durability. But this time, we have added  PoE-in & PoE-out  on all eight Ethernet ports. Combined with the 2-pin connector and the DC jack, you’re getting 10 separate ways of powering. Dual redundant power supplies would usually take your uninterrupted uptime to the next level.  RB5009UPr+S+IN  takes it one step above that! 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 . 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. 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
