The Microsoft Excel spreadsheet report
includes time and date of testing, as well as
notation of the test instrument (IP Address and
Test Port) utilized. Users may enter test site
or outlet information into the report header.
Additionally, if an
In-Band
test configuration
is utilized (see PoE Service Test
Configurations below) and the Ethernet LAN
link is found to drop and return as PoE power
is applied or removed, a link delay parameter
will be provided to note the time delay that
might occur between a PD power-up and
actual link communications.
Text reports (see Figure 8.2) may also be
produced when running all or a subset of the
PoE Service Access Tests. These reports are also time-date stamped and carry much of the same information included
in the spreadsheet report.
9.3. PoE Intermittent Service Detection
The
PoE Service Analyzer
also includes an automated
Line Monitor
designed to capture intermittent service drop-outs. This test may be
configured to run with PD Class 1, Class 2, or Class 3 emulation.
Users select between a
30 minute
test and a
12 hour
test, though in
either case, user’s have the option to terminate monitoring at any time
and recover results.
Intermittent Service Detection
is sensitive to power drops that are
either instantaneous or of longer durations. The test will report a
count of observed drops as well as the elapsed time until the first
observed service drop-out.
Testing for intermittent
PoE service at any test
site or outlet may can be
beneficial both for
assessing intermittent
connections and for
capturing PSE behaviors
