Synergy 21 Tester TP RJ45 PoE at/af Endspan/Midspan Standard

The Synergy 21 TP RJ45 PoE Tester is a compact and reliable tool designed for network professionals to verify Power over Ethernet (PoE) availability and standards on RJ45 cabling. It supports both IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, detecting power delivery from endspan (Mode A) and midspan (Mode B) sources. With clear multi-color LED indicators, it shows power presence, polarity, and mode, making it ideal for installation, troubleshooting, and maintenance of PoE networks.

Advantages

This PoE tester offers quick and accurate detection of PoE power, saving time during network deployments. Its compact design and LED indicators provide immediate visual feedback, eliminating the need for complex setups. The device is passive, drawing power from the source under test, so no batteries are required. It is compatible with all standard PoE switches, injectors, and powered devices, ensuring broad applicability.
