Chapter 6: Operation

NETWORK PORTS (USE RIGHT JACK): Select Network Ports to display the capabilities of a LAN device. LAN devices broadcast their capability in terms of speed, duplex, and other features (termed “advertised capabilities”) to other LAN devices. When two LAN devices are connected together, they “negotiate” to attain the highest common denominator for communicating on the link. For instance, a Gigabit switch with an advertised capability of 1000 Mbps, full-duplex will negotiate down to

100Mbps, half-duplex when connected to a 100-Mbps, half- duplex LAN device. The LPV displays individual LAN devices advertised capabilities and also can connect INLINE between two LAN devices to display the negotiated results.

NOTE: The RIGHT jack is protected from PoE voltage. Use it when connecting to devices.
