11-12 Guidelines for Creating or Modifying Actions
LX Series Configuration Guide
X To configure a power port async lost contact trigger
L This command applies to all power units.
Execute the power port async <port_number> lost
contact command from the Trigger-Action Command Mode
to poll the power device with status commands (every 10
seconds). If the device does not respond within a certain time
period, the LX is considered to have "lost contact" with the
device and the action is performed. The trigger does not
perform the action again until a successful response is
received, and then followed by another timeout:
Example Trigger_TestA:0 >>power port async 2 lost contact
where the port number is the port on which you want to
detect loss of contact with the attached device.
X To monitor the power threshold based on total power
per input
L Certain 5250 Power Control models are three-phase.
5250 models supporting three phase power input can
set trigger-actions on each phase individually. Using
a 5250 three phase unit is similar to having three
power strips in one unit, the new features apply to
each phase individually. On 4800 DC models, you can
set thresholds on individual ports as well as on the
device as a whole.
Execute the power port async <port_number> load <|>
<threshold_number> input A|B|C [hysteresis
<hysteresis_number>] command to perform monitoring on
a specific input (for Power Control 4800 and 5250 series
only):
Trigger_TestA:0 >>power port async 12 load
< 8 input A hysteresis 1
If the defined threshold is exceeded, the appropriate action is
executed when the rule is enabled. Valid threshold values are
in the range from 0.0 to 65534.9. Valid hysteresis values are
in the range is 0.0 to 9.9 (note that you can use decimals).
