This RB5009 has all the features of the original model: Gigabit Ethernet, 2.5 Gigabit Ethernet and a 10 Gigabit SFP+ cage for fiber connectivity.
It has speed, power and durability with the added benefit of PoE-in and PoE-out on all eight Ethernet ports.
Equipped with a 2-pin connector and DC jack; dual redundant power supplies minimize any downtime.
All power supply options support a wide range of voltages from 24 to 57 V. However, you cannot mix voltages. If you use the PoE output to power other devices, the card will choose the source with the highest voltage (DC plug or 2-pin connector) to power them.
Each PoE output port can provide up to 25W of power. All ports combined are limited to 130W, which should be sufficient for most configurations.
You can manually specify the maximum available power from your power sources, if necessary.
When it comes to PoE output capabilities, the new RB5009 can compete with the larger PoE switches: CRS354 AND CRS328.
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 socket, 48V on the 2-pin connector, and 57V on the PoE-in. The board itself is powered by the highest voltage input - the PoE-in. If there is a problem, the RB5009 falls 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 PoE-out devices? Once again, the highest voltage wins out. PoE-out devices are powered by the 48V source on the 2-pin connector. If that fails, the 24V from the DC connector comes into play. The card always reserves 20 watts to power itself. If there is not enough power for all the PoE output ports, it will start disabling those with the lowest priority. You can manually set the priority of the ports.
This tiny form factor fits any environment, from research facilities to confined offices to huge corporate server rooms. And remember, you can fit FOUR of these routers in a single 1U rackmount space.
