Classification Service and Interoperability Tests
Classification Service Tests
report the behavior of the PoE service
connection to each PD classification (0, 1, 2, or 3). Information
reported includes maximum power capacity available by PD
classification as well as the ability of the PoE connection to deliver the
appropriate power capacity to PD classification signatures that are
borderline for each PD classification.

PoE Service Test Suite Reporting
The Sifos
PoE Service Analyzer
includes a colorful
Microsoft Excel
Test Report (
see Figures 3.4, 3.6
) that can be
automatically produced upon completion of the full set of PoE Service Access Tests. The report performs
limit checking
and
color formatting
of each test outcome. It also presents a graphical depiction both required and available power to
each PD Class, PoE line voltage and line noise across PD power levels, and transient (burst) power performance of the PoE
service.
