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 single-sided tests for advertised speed (10,
100, 1000 Mbps, and duplex) and inline tests (between devices)
for negotiated speed. The engine of the LPV circuitry is capable
of 1 nanosecond resolution.
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.
