IEEE 802.3af/at/bt Power over Ethernet Tester

PLANET POE-TESTER+ is a new generation easy-to-use PoE diagnostic adapter for network installers, system integrator, company MIS and even home users to quickly identify the existence of Power over Ethernet on applications network. It is designed to detect if the IEEE 802.3af/at/bt PoE voltage runs over the UTP cable and identify the type of PSE (Power Source Equipment) for troubleshooting.

Simply connect the POE-TESTER+ to the PSE or the RJ45 outlet and the LED will light up when it detects the PoE voltage via the UTP cable and identifies the PSE to be mid-span, end-span, 802.3af PoE mode, 802.3at PoE+ mode or even the latest 4-pair 802.3bt PoE++ mode in a second.

The POE-TESTER+ provides two bi-color LEDs for quick and easy PSE mode identification. A Power over Ethernet system comprises a PSE (Power Sourcing Equipment) and a PD (Powered Device). The PSE is a device that will provide power in a PoE setup. There are three types of PSE, Mode A, Mode B and 4-pair mode. The PSE may be a Mode A, end-span PoE switch or a Mode B, mid-span PoE injector or a 4-pair mode PSE that is end-span plus mid-span.

Although PDs that implement only Mode A with end-span or Mode B with mid-span are disallowed by the IEEE 802.3af/at standard, there are still some of the PDs that are designed to work with only one of the modes. Thus, it will cause the PoE PSE and PD not to be compatible with each other in the applications. For example, an end-span designed PoE switch cannot power on the remote mid-span only wireless access point. But most of the time, the installers would not exactly know what the remote PSE devices are. PLANET POE-TESTER+ checks your UTP cable for power and identifies its source, mid-span, end-span or mid-span + end-span. Make sure at the end of UTP cable there is existence of PoE, and then the next step is to check if the PD is compatible with the PSE, or it is a malfunctioned PD.
