DESCRIPTION
mitigates the possible opening of circuit breakers in the unit or upstream at the service. SWOCP is only
displayed and configurable for models having receptacle management.
NOTE: MPHX BRM, MPH2-C, MPH2-M and MPH2-R rack PDU models support the circuit breaker status. MPH2-B rack
PDU models utilize a software Loss of Load detection, which detects a sudden reduction of branch current after its
overcurrent alarm threshold is breached. This active event implies the circuit breaker has opened.
To edit a branch:
1.
Log in with the required privileges.
2.
From the
PDU Explorer
tab, click the rack PDU with the branch to be edited.
3.
Click in a branch field to highlight the branch and open its receptacle window.
4. In the table at the bottom of the window, click the
Settings
tab.
5.
Check the boxes next to the settings to be edited.
6. Click the Edit icon.
7.
Enter the new values.
-or-
Use a drop-down menu to do one of the following:
•
Enable or disable software overcurrent protection.
•
Change whether the branch is designated critical or non-critical.
8.
When finished, click the Save icon to make the change or click the Cancel icon to abort the change. The icons
will be in the column formerly occupied by the Edit icon.
3.4.5 Receptacle settings
The following procedures help you configure the receptacle settings. Review the table in this section for the receptacle
settings descriptions.
SETTING
DESCRIPTION
Over Current Alarm Threshold
Percentage of receptacle current rating to exceed before the corresponding event notification occurs.
Over Current Warning Threshold
Percentage of receptacle current rating to exceed before the corresponding event notification occurs. The
value must be less than the alarm threshold.
Under Current Alarm Threshold
Percentage of receptacle current rating to fall below before the corresponding event notification occurs.
The value must be less than the warning threshold. A zero value disables the alarm.
Power Up State
After mains power is applied, the receptacle is either immediately turned on, turned off or is restored to the
last power state before the loss of power occurred and after the Power On Delay has expired. If the last
power state was off, the power remains off.
Power On Delay
The amount of time, in seconds, before the receptacle power is restored after mains power is applied.
Power Cycle Delay
The amount of time, in seconds, that receptacle power is momentarily turned off.
Post On Delay
The amount of time, in seconds, before receptacle power is turned on.
Post Off Delay
The amount of time, in seconds, before the receptacle power is turned off.
Software Over Temperature Protection
(SWOTP)
If enabled, affected receptacles automatically have power turned off after the measured temperature
breaches the over temperature alarm threshold of a temperature sensor for at least the duration of the
SWOTP delay. The SWOTP can be configured for local mode which is only affected by alarm of
temperature sensor(s) connected to its RPC2 module, or array mode which is affected by alarm of
temperature sensor(s) connected to any RPC2 module in the array.
Receptacle Criticality
If disabled, the receptacle automatically turns off if SWOTP is enabled and the condition is active. SWOTP
automatically turns off receptacle power to non-critical and unloaded receptacles (no current draw) when
input and/or branch overcurrent alarm conditions occur in order to mitigate a possible opening of circuit
breakers in the unit or upstream at the service.
