Multiple Power Sources
Our outdoor cellular routers offer flexible powering options for different deployment scenarios. They can be powered by a PoE injector, PoE switch, 12Volt DC power, and even a 12V battery pack.
PoE (Power over Ethernet) provides electric power over Ethernet data cables. PoE technology allows Ethernet network equipment to receive power and data over a single Ethernet cable. PoE removes the requirement for a separate power source to power network equipment, simplifying installation and cabling. PoE is widely used for IP cameras, VoIP phones, smart building equipment, industrial automation, and other applications.
Note: Only outdoor models and indoor EZR23 series support PoE power sources.
Our outdoor PoE cellular routers follow industry standards IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) safely and ensure interoperability between PoE PSE (power sourcing equipment) and PDs (powered devices).
Endpoint PSE — Uses PoE power injectors or PoE-enabled Ethernet switches that attach to network equipment to inject power onto spare wire pairs in the Ethernet cable.
Midspan PSE — It’s a standalone PoE power unit placed between the PoE PSE and the powered device to inject the power, such as a PoE extender, that is designed to extend the PoE cable length and reduce the digital Ethernet signal attenuation.
PoE vs. PoE+ — The mostly used PoE standards are IEEE 802.3af (PoE) and IEEE 802.3at (PoE+). The PoE IEEE 802.3af supplies up to 30Watt power on 48 volts, while IEEE 802.3at supplies up to 60Watt power on 52 Volts. All of our PoE-enabled routers support both IEEE 802.3af/at standards.
Non-standard PoE Power — Please use the default PoE injectors provided with our router. When you need to use other PoE PSE equipment, ensure they are on the IEEE 802.3af/at standards. Using non-standard PoE power sources such as 12Volt, 24Volt, or reversed wiring might cause damage to the power module.
Ethernet Cable — PoE works over standard Ethernet cable types, including Cat.5, Cat.5e, Cat.6, and Cat.6a cables. No special PoE cables are needed. Please remember that both RJ45 connectors must use the same T568B standard wiring type.
The PoE injector is connected to an AC electric power outlet and supplies DC power to the router over an Ethernet cable. It allows the router to mount in a remote area where AC power is far away. You can connect a computer or indoor router to the LAN port on the PoE injector to access Ethernet provided by the outdoor router.
The Ethernet signals are digital packets with minimum signal attenuation. Hence, the outdoor router with PoE Ethernet provides stabler connectivity than the indoor cellular router with external RF antennas.
For multiple PoE device installations, the outdoor router can draw PoE power from an Ethernet PoE switch that supports the 802.3af or 802.3at PoE standards, and then provide Ethernet signal to the other PoE ports linked to cameras, computers, access points, etc. This installation solution eliminates separate PoE injectors.
The standard PoE distance is within 50 meters. When AC electric power is too far, you can install max 3 units of the PoE extenders between the Ethernet cable to boost the electric power and reduce the Ethernet signal attenuation. It helps the PoE PDs connect to PSE with low latency.
DC Power Sources
The outdoor router models, such as EZR33(L) and EZR34 series, have a spare DC power socket that can take a wide-range 9~48Volt DC power source, such as AC/DC power adapter and battery pack.
The DC power source design allows outdoor routers to draw power from regular AC/DC power adapters and battery packs, such as vehicle and rechargeable solar batteries. It enhanced the workability for off-grid deployments and remote areas without AC power deployment.
Note: To work with solar power, you need to use a solar regulator or charge controller to avoid over-current damage.
The suggested typical DC power is 12Volt 1~2Amps. Do not overload the current to avoid damage on the power module.
Using above mentioned flexible powering options, the outdoor routers are ideal for mobilizing M2M and IoT equipment across all environments. They provide always-on connectivity wherever and whenever needed.
