Utility generates a configurable loading sequence to a
powered PSE port that runs for a user specified duration.
This can be used in conjunction with data transmission tests
performed by other test equipment.
slow
:
A slowly varying (~ .5 Hz), approximately sinusoidal
loading waveform ranging from .5 watts to a power level
just below the maximum classification power level. This
is the default waveform.
fast
:
A rapidly varying (4 Hz) series of step transitions
between low power and a power just below the maximum
classification power level.
sharp
:
Approximately 5 very short duration load transients
per second ranging from low power to the maximum
classification power level.
c
:
Specify a PD Classification. Default is Class 0.
class
:
User specified PD Classification. Test loads vary over
the following ranges according to selected classification:
Class Min Load Max Load
0 0.5 Watts 15.3 Watts
1 0.5 Watts 3.9 Watts
2 0.5 Watts 6.9 Watts
3 7.1 Watts 15.3 Watts
4 15.5 Watts 32 Watts
Note! Class 4 Requires Port Combiners
-force
:
Recycle power to PSE port using PD Classification
Emulation for the desired class level entered to assure
proper classification.
t
:
Specify a time duration for the load sequence.
duration: Time duration in seconds. Range is 5 to 240
seconds. Default is 10 seconds.
config_type { target_ports }
replicate_
ports
port
Replicate configuration of resources from one port to one or
more other ports in a PSA1200 or PSA2400.
config_type
: The type of configuration to be replicated from
<port> to {target_ports}. Options are:
port

vdcp
|
vdct

l.
“
all
” will fully replicate all subsystem configurations.
target_ports
: A list of all ports to which the configuration is
to be copied. Each port is in the same form as <
port
>,
that is “slot#, port#” and is space delimited in the list.
4.9. PowerShell Trace Display and Analysis Commands
PowerShell offers several commands that are useful for working with voltage and current traces gathered from the
respective trace meters.

psa_trace
This utility will create and O-scope display (see Section 3.1.10)
given a captured trace from a PowerShell command or script.
v
: Waveform is a voltage trace.
i:
Waveform is a current trace.
PSA_Trace_Data
: The TCL list of 256 time-value data returned
from a
vdctrace stat
or
idctrace stat
measurement.
Note! This command will only run in PowerShell Wish
