PoE (Power over Ethernet) has become a popular medium to deliver power and transmit data for outdoor equipment. Outdoor devices compatible with PoE range from security cameras to WiFi Access points and fixed wireless equipment.


Outdoor mounted PoE equipment increases the risk of damage from high-voltage surge events. This equipment acts as a lightning rod and passes the voltage through the copper ethernet cable, increasing the risk of damage to sensitive equipment in the data center, and physical harm to personnel.


How Do I Protect Outdoor PoE Devices from Surge?


Surge protection is an important preventative measure to avoid extensive damage. For outdoor PoE equipment, it's important to protect the device and the supporting equipment like switches and routers.


It's best practice to install two inline surge protectors for each device. The first surge protector is installed near your switch or router. This protects equipment from voltage entering the building and damaging the equipment inside. The second surge protector should be near the outdoor PoE device.


Two surge protectors for each device may sound excessive. However, a surge can enter the ethernet cable at any point and travel in either direction. Two surge protectors ensure that all your equipment is protected.
