4.4.3MP Advanced Power Strip Thresholds

When using the OpenComms EM to monitor MP Advanced Power Strips, you may set thresholds that will trigger alerts for power, voltage, current and temperature sensors in each power strip.

Each sensor has four thresholds: High Critical, High Warning, Low Warning and Low Critical. The Normal range is determined by these limits. Table 9 shows examples of limits for these types of sen- sors. Each level is color-coded in the Web interface for easy identification.

Table 9 Examples of sensor limits - MP Advanced power strip sensors

		Examples of Limits			Text Display Color		Graph
	Power	Voltage	Current	Temperature	Serial Port	Status &	Line
Limit	(Watts)	(VAC)	(Amps)	(°F)	Name	Current Value	Color
High Critical	2400	132	20	85	Red	Red	Red
High Warning	1900	126	16	75	Yellow	Yellow	Yellow
Low Warning	1000	114	8	65	Yellow	Yellow	Yellow
Low Critical	500	108	4	60	Red	Red	Red
Other conditions
Normal	1 to 6999	115 to 125	0.1 to 19.9	66°F to 74°F	Green	Green	—
Not Present		(sensor is not connected)			Gray	Black	—

Using the examples of temperature sensor limits in Table 7, the following is a typical scenario:

•The temperature of a monitored area rises to 90°F. The status changes at two points:

•The status changes to High Warning when the temperature reaches 75°F. The serial port name, current reading and status are displayed in yellow text in the Web interface.

•As the temperature continues to rise, the status changes to High Critical at 85°F (displayed in red text).

•At each change in status, the unit sends alerts if it is configured to do so.

•When the temperature falls to 74°F, the status changes to Normal (displayed in green text) and a return-to-normal alert is sent if the unit is configured to send alerts.

•When the serial cable is disconnected from the unit, the status changes to Not Present (black text) and the serial port’s name appears in gray text.
