idcaverage_2
Configures and performs an Average DC Current measurement on a PoE Pair up to 1022 mA.
tr ig off
enables immediate execute of DC measurement when “stat” query is issued.
tr ig on
specifies that the measurement will be performed when the trigger condition specified
on Trig1 is achieved. Trig1 will be armed automatically when “stat” query is issued.
tr ig ext
specifies that the measurement will be performed when the external input trigger is
asserted.
p eriod
specifies that an averaging period will be defined.
interval
specifies the averaging period as “Nm” where N is 10, 20, 50, 100, 200, 500 mSec or
“Ns” where N is 1, 2, 5, or 10 seconds. Default value is 100 mSec.
ti meout 10
specifies that a hardware triggered measurement should time out if no trigger is
found within 10 seconds following trigger arm.
ti meout 100
specifies that a hardware triggered measurement should time out if no trigger is
found within 100 seconds following trigger arm.

idcpeak_2
Configures and performs a Peak DC Current measurement on a PoE Pair up to 1022 mA.
tr ig off
enables immediate execute of DC measurement when “stat” query is issued.
tr ig on
specifies that the measurement will be performed when the trigger condition specified
on Trig1 is achieved. Trig1 will be armed automatically when “stat” query is issued.
tr ig ext
specifies that the measurement will be performed when the external input trigger is
asserted.
max
specifies that a maximum peak over the sample period should be measured.
min
specifies that a minimum peak over the sample period should be measured.
p eriod
specifies that an sampling period will be defined.
interval
specifies the sampling period as “Nm” where N is 10, 20, 50, 100, 200, 500 mSec or
“Ns” where N is 1, 2, 5, or 10 seconds. Default value is 100 mSec.
ti meout 10
specifies that a hardware triggered measurement should time out if no trigger is
found within 10 seconds following trigger arm.
ti meout 100
specifies that a hardware triggered measurement should time out if no trigger is
found within 100 seconds following trigger arm.

idctrace_2
Configures and performs a DC Current Trace measurement on a PoE Pair up to 1022 mA.
tr ig off
enables immediate execute of DC measurement when “stat” query is issued.
tr ig on
specifies that the measurement will be performed when the trigger condition specified
on Trig1 is achieved. Trig1 will be armed automatically when “stat” query is issued.
tr ig ext
specifies that the measurement will be performed when the external input trigger is
asserted.
p eriod
specifies that an sampling period will be defined.
interval
specifies the sampling period as “Nm” where N is 10, 20, 50, 100, 200, 500 mSec or
“Ns” where N is 1, 2, 5, or 10 seconds. Default value is 100 mSec.
ti meout 10
specifies that a hardware triggered measurement should time out if no trigger is
found within 10 seconds following trigger arm.
ti meout 100
specifies that a hardware triggered measurement should time out if no trigger is
found within 100 seconds following trigger arm.

stat
paverage_2
Performs an immediate average power measurement and returns power in watts. Since this
measurement function uses vdcaverage_2 and idcaverage_2, there is no memory for the
configuration and the “?” query is not supported. “stat” must be specified on each execution of
the command.
p eriod
specifies that a sampling period will be defined.
interval
specifies the sampling period as “Nm” where N is 10, 20, 50, 100, 200, 500 mSec or
“Ns” where N is 1, 2, 5, or 10 seconds. Default value is 100 mSec.

psa_disconnect_2
Forces a PSE Port power-down to occur. Opens the port switch, sets DC current load to 0 mA.
