Managing Alarms

Managing Alarms

By managing alarms, you can learn about and monitor the real-time status of the system. In this way, you can detect faults, improve fault locating efficiency, and handle faults in time to ensure the normal running of the system.

Managing Alarm Notification

By managing alarms, you can learn about the real-time system status as well as promptly discover and troubleshoot faults (if any), ensuring proper system running.

Managing Email Notification

DeviceManager allows fault information to be sent to specific email addresses, helping engineers locate and troubleshoot faults.

Context

Only the super administrators and administrators can manage alarms. System administrators can only view alarms.

Procedure
  1. Log in to DeviceManager.
  2. Choose Settings > Alarm Settings > Alarm Notification > Email Notification.
  3. Add an email address for receiving alarms.

    1. Set Enable to the on state.
    2. Set email notification parameters. Table 4-7 describes related parameters.
