Changing an Entry in the Frame Power Alarm Threshold Table

This procedure is used to change an existing entry in the frame power alarm threshold table. The frame entry in the power alarm threshold table is changed using the chg-frm-pwr command with these parameters:

:frm – The name of the frame being added to the power alarm threshold table, cf00, ef00, ef01, ef02, ef03, or ef04.

:thrshld – The power threshold value, from 30 to 65 amps.

The frame power alarm threshold table defines the power level threshold, in amps, for each frame in the EAGLE. The power level threshold determines when alarms regarding the amount power used by the frame are generated. Three alarms can be generated for the power levels.

UAM 0522 - a minor alarm indicating that the power level for the frame has reached 90% of the threshold value.
UAM 0521 - a major alarm indicating that the power level for the frame has reached 95% of the threshold value.
UAM 0520 - a critical alarm indicating that the power level for the frame has reached 98% of the threshold value.

More information on these alarms is shown in Unsolicited Alarm and Information Messages Reference.

When setting the threshold value (the thrshld parameter value), the threshold value should be greater than the amount of power being used by the frame. The power being used by the frame is displayed in the Power Consumption (Amps) column in the rtrv-stp output. The threshold value should also be high enough to avoid generating any alarms.

Table 4-7 shows selected threshold values and the power levels for a frame that would generate a minor alarm for that threshold value.

Threshold Value	Power Level to Generate a Minor Alarm
30	27
35	31.5
40	36
45	40.5
50	45
55	49.5

Display the power consumption of the frame that will be changed in the Frame Power Alarm Threshold table by entering the rtrv-stp command with these parameters:

display=power

frm =<frame being changed>

For this example, enter this command.

rtrv-stp:display=power:frm=ef01

This is an example of the possible output.

Command Completed.

Changed the entry in the Frame Power Alarm Threshold table by entering the chg-frm-pwr command with these parameters.
frm =<frame being changed>

thrshld=<frame power threshold level>

A minor alarm (UAM 0522) is generated when the power level for the frame reaches 90% of the threshold value. A major alarm (UAM 0521) is generated when the power level for the frame reaches 95% of the threshold value. A critical alarm (UAM 0520) is generated when the power level for the frame reaches 98% of the threshold value. When setting the threshold value, the threshold value should be greater that the Power Consumption (Amps) value shown in the rtrv-stp output in step 2, and high enough to avoid generating any alarms. See Table 4-7 for some examples of threshold values and the power levels for a frame to generate a minor alarm for these threshold values.

For this example, enter this command.

ent-frm-pwr:frm=ef01:thrshld=45
