Planet POE TESTER

Quickly and easily test an RJ-45 outlet for Power over Ethernet presence in one second.

The Planet PoE Tester is an easy-to-use PoE diagnostic adapter for network installers, corporate IT professionals, and even home users. This tester allows you to quickly check the presence of Power over Ethernet on a network. It is designed to detect the presence of IEEE 802.3af/at PoE voltage on the UTP cable and to determine the type of PSE (Power Source Equipment) used for troubleshooting.

Plug and Show LED indicator

Simply connect the POE TESTER to the PSE or the RJ-45 outlet and the LED will light up when it detects PoE voltage over the UTP and instantly identifies the PSE as mid-span, end-span, or even the latest 4-pair 60 Watt ULTRA-POE.

Identify PoE PSE modes

The POE TESTER offers two LEDs for quick and easy PSE mode identification. A Power over Ethernet system consists of a PSE (Power Sourcing Equipment) and a PD (Powered Device). The PSE is a device that supplies power in a PoE installation. There are two types of PSE: Mode A and Mode B. The PSE can be a Mode A, end-span PoE switch or a Mode B, mid-span PoE injector.

The PD is a PoE-using unit that draws its power from a PSE such as IP network cameras, VoIP phones, and wireless access points and others.

PoE installation troubleshooting

Although PDs that only use Mode A with end-span or Mode B with mid-span are no longer permitted by the IEEE 802.3af/at standard, there are still PDs that only work with one of the modes. This makes the PoE PSE and PD incompatible in applications. For example, an end-span PoE switch cannot remotely power up a "mid-span only" wireless access point. However, installers often don't know exactly which remote PSEs are. The Planet PoE Tester checks your UTP cable for power and identifies the source, mid-span, or end-span. Ensure there is PoE at the end of your UTP cable, and the next step is to check whether the PD is compatible with the PSE or whether there is a fault in the PD.
