Which cables to use
The quality of the cables is determined by the material they're made of, the shielding of the cable, the category of the cable and the wire diameter of the cable (expressed by the AWG number).
Your cables should be:
Pure Copper (CU) and not Copper Clad Aluminium (CCA)2
Shielded Foil Twisted Pair (S/FTP) to eliminate cross talk3
CAT6 (or better)4
AWG24/1 or AWG 24/7 (or better)5
It is of great importance that the connectors on the cables are properly fixed and tested with a cable tester.
Which switches to use
An anchor uses ± 5 W (watt), therefor your switches should:
Have PoE+ (802.3at)
Deliver at least (5 W x max number of anchors connected on 1 port) per port.
E.g. If you want to go up to 4 anchors on a chain you'll need a switch that delivers at least 5 W x 4 = 20 W per port.
Deliver at least (5 W x total number of anchors connected to the switch) in total.
E.g. If you want to have 16 anchors connected to the switch you'll need a switch that delivers at least 5 W x 16 = 80 W in total.
For smaller setups we can recommend the Ubiquiti UniFi Switch 8-150W (https://www.ui.com/unifi-switching/unifi-switch-8-150w/) as an affordable and good price-quality switch.
Connecting the anchors
The anchors each have two ethernet (RJ45) ports. These can be used to link up anchors in sequence which reduces the total amount of wiring required. We call this daisy chaining of anchors. Power only needs to be provided to the first anchor in such a chain. This can be done in two ways, either using the DC power jack, or by Power over Ethernet. For Power over Ethernet, PoE+ (802.3at) is required.
Make sure that you use the correct ports to connect the incoming and outgoing Ethernet cables on the anchor as is depicted in the figures below.
PoE IN and OUT-going cables are installed in a crossed way:
The maximum number of anchors in one chain depends on how they are powered, and the quality of the cables. Using cables and switches which comply with our specs below you'll be able to have a maximum of 4 anchors on a chain, with a maximum of 50 m between each anchor (which means that 1 chain of anchors will have a maximum length of 200m). More anchors on a single chain will cause issues.
Validating the anchors
Each anchor has a LED light on it which will give you feedback about the current state of the anchor. This LED light can be very useful during installation to detect problems on the spot, and will allow you to take immediate action on common issues like cabling issues. But the LED will only give you useful feedback when the anchor gets connected to the gateway, which means it's best to already have the gateway and switches in place before the installation of the anchors.
When you plug in the Ethernet cable in the anchor, and it gets power, the anchor will start up in bootloader mode in which the LED will be blue. After approximately 7 seconds the anchor will then go to the firmware and follow this flow:
The anchor is powered off
LED blinking red
The anchor has a general malfunction
LED solid blue
The anchor is in support / maintenance mode
LED solid red
The anchor has no link (= it is powered but not linked to the network)
LED blinking orange
The anchor is linked but did not receive an IP address
LED solid orange
The anchor has received an IP address
LED blinking green
The anchor received a heartbeat / is starting up tasks
LED solid green
The anchor is in normal operation mode
