Cable tester DEFENDER Delock 63110 RJ45 PoE — RJ45 cable continuity and PoE detection

Handheld cable tester DEFENDER Delock 63110 RJ45 PoE is a compact tool designed to check RJ45 Ethernet cables for continuity, wiring faults and the presence of Power over Ethernet (PoE). The device is intended for installers and IT technicians who need a portable tester to verify correct cable wiring and detect whether Ethernet lines supply PoE before connecting sensitive equipment. Its small form factor and straightforward indicators make it suitable for on-site troubleshooting and pre-deployment verification of network cabling.

Advantages

The tester provides quick verification of RJ45 cable continuity and common wiring faults without requiring a laptop or additional equipment. Integrated PoE detection allows users to identify the presence of Power over Ethernet on a cable, helping to prevent accidental connection of non-PoE devices to powered lines. The handheld design supports easy transport and one-handed operation in tight installation environments. Clear status indicators simplify interpretation of test results for both experienced technicians and installers.

Suitable for

• Installation and verification of Ethernet patch cables in office and data center environments
• Troubleshooting network cabling faults during on-site maintenance
• Checking whether Ethernet lines carry PoE before connecting cameras, access points or VoIP phones
• Field testing by IT technicians and structured cabling installers

Key specifications

• Connector type: RJ45 network cable interface for testing
• Functions: continuity check, wiring fault detection, Power over Ethernet presence detection
• Form factor: handheld, portable tester suitable for field use
• Indicators: visual indicators for cable continuity, wiring status and PoE detection

How to use

Connect one end of the RJ45 cable to the tester's port and, if applicable, connect the remote terminator to the opposite end. Power on the device and initiate the test sequence according to the tester's control. Observe the visual indicators to determine continuity, identify any wiring faults such as opens or shorts, and verify the presence or absence of PoE on the cable. Interpret the results using the device's indicator scheme; if PoE is detected, avoid connecting non-PoE devices to that line without proper power management.

Usage recommendations

Use the tester before terminating, deploying or connecting end devices to ensure cable integrity and to confirm whether the Ethernet line carries PoE. Store the device in a protective case when not in use and avoid exposing it to moisture or impact. For consistent results, test cables with both ends accessible and follow standard safety practices when working near powered network equipment.
