GN-RJ45/1000/POE Signal Surge Protective Device — RJ45, 1000 Mbps, PoE

Description

The GN-RJ45/1000/POE is a signal surge protective device for network equipment that uses Category 5 or higher cabling as its transmission line. It is installed directly in front of the equipment or system being protected, with separate routing of the IN and OUT leads, and it protects both the signal pairs and the power pairs carried on the RJ45 interface.

Product Overview

The device is intended for overvoltage protection of network equipment. Typical protected equipment includes computer network servers, routers, hubs, network switches, and broadband equipment. It supports a transmission rate of 1000 Mbps and uses an RJ45 interface.

Protection is provided on two groups of conductors: 8 wires (Pin1–Pin8) on the signal side and 4 wires (Pin4/5/7/8) on the power side. The signal side has a nominal voltage UN of 5V, and the power side has a nominal voltage UN of 48V.

Key Features

• Combined signal and power protection within a single RJ45 device
• 1000 Mbps transmission rate with insertion loss of ≤0.5 dB
• Signal side: UN 5V, In 1kA (8/20μs), Imax 2kA (8/20μs), Up ≤20V
• Power side: UN 48V, In 3kA (8/20μs), Imax 6kA (8/20μs), Up 150V
• 8-wire signal protection (Pin1–Pin8) and 4-wire power protection (Pin4/5/7/8)
• Operating temperature range of -40℃ to +85℃
• IP20 enclosure measuring 110 × 40 × 27 mm (±1 mm)

Applications

The GN-RJ45/1000/POE is intended for network equipment that uses Category 5 or higher cabling as its transmission line, including computer network servers, routers, hubs, network switches, and broadband equipment.

Installation and Use

• Install the device directly in front of the equipment or system being protected. The closer the installation is to the protected equipment or system, the better.
• The “IN” terminal connects to the incoming line, and the “OUT” terminal connects to the protected equipment or system.
• The lines at the two ends must be routed separately and must not be bundled together, to prevent secondary induction.
• When installed within the specified conditions, the device does not require long-term maintenance; only routine system maintenance is needed.
• If a signal transmission problem occurs and normal transmission returns after the surge protective device is removed, the device has been damaged and must be repaired or replaced.

Frequently Asked Questions

What equipment can the GN-RJ45/1000/POE protect?

It is designed for network equipment using Category 5 or higher cabling, such as computer network servers, routers, hubs, network switches, and broadband equipment.

Which conductors are protected?

The signal side protects 8 wires (Pin1–Pin8), and the power side protects 4 wires (Pin4/5/7/8).

How should the IN and OUT lines be routed?

The two ends must be routed separately and must not be bundled together, to prevent secondary induction.

How can I tell whether the device has been damaged?

If signal transmission problems occur and normal transmission returns after the surge protective device is removed, the device has been damaged and needs repair or replacement.
