The HGLN-CAT5-2 provides lightning and surge protection for CAT5 data applications. The unit is compatible with industry-standard IEEE 802.3af Power-over-Ethernet (PoE) devices and 10/100 Base-T Ethernet networks, providing protection to both Ethernet data pairs as well as the PoE DC power feed.

High speed semiconductors clamp any voltage, positive or negative on the wires. The limits are +/- 15 volts on pins, 1, 2, 3 and 6 and +/- 58 volts on pins 4, 5, 7 and 8. The unit is compatible with both normal and inverted polarity voltage PoE equipment. Most PoE capable equipment is not protected from surges on its CAT5 cable.

This lightning surge protector is compatible with Cisco legacy network appliance products like access points, DC injectors and other equipment supporting reverse polarity PoE pinouts.
