Surveillance Tasks for Alarms
Setting OC-3 Alarm Thresholds
The chsonetalm command changes the configuration settings for alarm severity, integration period, and
thresholds for various error counters. The performance alarm is set if the errors exceed any of the
threshold counts set by this command. To change alarm threshold values, enter the chsonetalm
command as described in the “chsonetalm” section on page 9-116.
Monitoring Environmental Alarms
The MGX 8260 Media Gateway monitors three key environmental conditions:
Temperature of the SCC, BSC, NSC, and DMC
Voltage on the backplane and at each card
Chassis fan rotation speed
Sensor readings translate to alarm conditions according to four fixed threshold levels (see Figure 6-1).
