The board features 9 wired ports and a full-sized USB 3.0. Seven of the ports are Gigabit Ethernet, another one is 2.5 Gigabit Ethernet, and the last one is a 10G SFP+ cage. All the ports are connected to a powerful Marvell Amethyst family switch-chip with a 10 Gbps full-duplex line leading to the Marvell Armada Quad-core ARMv8 1.4 GHz CPU. Both CPU and the switch-chip are located on the bottom of the board – so the case acts as a massive heat-sink!
RB5009UG+S+IN can be powered in 3 different ways:
a) PoE-in from Ethernet port #1
b) DC Jack
c) 2-pin terminal on the side
The GPeR unit allows to extend Ethernet cable by additional hop (< 100 – 150 m to regular network devices, and up to 210 m to another GPeR unit) up to 1,500 m.
Handy for highrise buildings, multi-apartment buildings, with many floors and sections, where very long Ethernet cables might be a problem.
Maximum allowed length of CAT6 Ethernet cable between GPeR and power source/router is up to 100 m (depending on cable quality, high quality – up to 150 m).
Maximum allowed distance of CAT6 Ethernet cable between two GPeR devices is up to 210 m (depending on cable quality).
In case if the destination device does not support PoE-in powering, the PoE Passthrough can be disabled by manually removing all jumpers.
GESP is Gigabit Ethernet Surge Protector that can be used to protect the network from lightning or surge damages.
Here’s what a typical use-case would be like. You have a mast with some antennas. And some switches on the ground. Put the GESP surge protectors on each end. They come sealed inside a new and improved IP67 weatherproof enclosure. Your antennas are now safe during a lightning storm.
Don’t forget about the grounding wire! Secure it to the rackmount, mast, or any other structure that is connected to the ground. For maximum protection, you should use a surge protector on both ends of long cables.
