Chapter 2: Overview
Help with device installation and PoE:
Installers of VoIP phones, IP cameras, or access points should use a power panel for exact measure- ments of PoE voltage and power usage, displaying the presence of 10,100,1000 switches and the pair location of each.
NOTE: Power over Ethernet (PoE) powers devices over the CAT5/6 cable.
2.4 Applications
Works with UTP and all Ethernet devices: Unlike traditional certifiers, the LAN Performance Verifier (LPV) uses digital circuit- ry and digital testing techniques to perform its tasks. These tests include traditional TIA568 cable verification (length, opens, shorts, split pairs, wire map) for unshielded twisted pair (UTP) plus the LPV's own sophisticated crosstalk, timing, and cable parameter tests that yield a UTP cable's category (CAT3, CAT5, CAT5e, CAT6) and speed capability (10, 100, 1000 Mbps). And the LPV can use your own network devices (hubs, switches, PCs) to test UTP cables with real data. The LAN Performance Verifier analyzes links and data from all types of hubs, switches, and PCs. It performs both
Works with coax cable: Use the LPV to test for the length of the cable, opens, shorts, wiremap, and distance to any faults that might exist. As with UTP, coax can be toned with the toner feature and test results can be stored in the LPV’s flash memory for printing later. No LPV tests are performed on coax cable.
