PoE Tester Identifies PSE Type

IT administrators and system intrgators and installers can use Power Dsine's Power over Ethernet (PoE) Tester to find out if these jacks are hot. PoE Testers connected to an RJ-45 outlet check for the presence of electrical power. They also identify whether the power-sourcing equipment (PSE) is an endspan or PoE midspan device. And, the PoE Tester can detect operating electrical power originated by Cisco pre-803.3af standard in-line power switches. Available from PowerDsine's distributors, the PoE Tester costs $19.99.
