PoE Line Monitor Report
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 Section 4
) 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 3.5
) 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.
3.2.
PoE Monitoring Test
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 where Class 3 would be the most
strenuous in terms of power consumption. 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
at a particular outlet when power demands or other
intermittent transitions are exceeding total output power
capacity across a range of PoE served devices. Line
Monitor Test Reports can be saved to a time-date
stamped text file (
see Figure 3.8
) upon test completion.
