In the project management interface, click Alarms to enter the alarm management interface. In this interface, you can view the alarm information in the current project. An alarm can be searched based on the AP’s serial number, alarm type, alarm level, and alarm occurrence time.
| Type | Status | Description |
| Device goes offline | The AP is offline. | The AP is disconnected from the cloud or is powered off. |
| Device goes offline and online continually. | The times of the AP going online or offline within two hours exceeds the default threshold. | The connection between the AP and the JaCS is unstable, or the AP has a firmware or hardware failure. |
| All devices are offline | All APs in the project are offline. | N/A |
| High channel usage on AP | The RF channel utilization exceeds 80%. | The RF channel utilization is too high and the interference is strong. It is recommended to change the channel. |
| System usage(CPU/memory usage) above threshold | The CPU or memory usage of the AP/switch/gateway exceeds the threshold. | For APs, the default thresholds for CPU usage and memory usage are both 85%. For switches, the default threshold for CPU usage is 50%, and the default threshold for memory usage is 65%. For gateways, the default threshold for CPU usage is 50%, and the default threshold for memory usage is 65%. Custom values are not supported. |
| Switch loopback detected (RLDP) | A loop occurs on the switch. | N/A |
| Abnormal network access on gateway | The gateway port was unable to successfully ping the specified domain or IP address multiple times. | When the number of ping test failures reaches the specified number, an alarm will be issued. The number of times and domains/IP addresses can be manually configured. |
| High packet loss speed on gateway | The packet loss rate on the gateway exceeds the threshold. | When the packet loss rate exceeds the threshold multiple times within 5 minutes, an alarm is generated. The number of times and the threshold can be manually configured. |
| Uplink speed above threshold on gateway | The uplink rate exceeds the threshold multiple times. | When the uplink rate exceeds the threshold multiple times, an alarm is generated. The threshold, number of times, and percentage can be manually configured. |
| Downlink speed above threshold on gateway | The downlink rate exceeds the threshold multiple times. | When the downlink rate exceeds the threshold multiple times, an alarm is generated. The threshold, number of times, and percentage can be manually configured. |
| Imported MAC, SSID and/or password checks | Importing devices. | When the imported MAC is inconsistent with the actual MAC, or the SSID/password is changed, an alarm is generated. |
| The RX power of lite-pon is higher than the threshold value | The RX power is higher than the threshold value. | Once the RX power exceeds the threshold value, an alarm is generated. |
| The RX power of lite-pon is lower than the threshold value | The RX power is lower than the threshold value. | Once the RX power is lower than the threshold value, an alarm is generated. |
| The TX power of lite-pon is higher than the threshold value | The TX power exceeds the threshold value. | Once the TX power exceeds the threshold value, an alarm is generated. |
| The TX power of lite-pon is lower than the threshold value | The TX power is lower than the threshold value. | Once the TX power is lower than the threshold value, an alarm is generated. |
The Alarm List shows the all alarms of the current project. To ignore generated alarms:
Step 1: Select the alarm to be ignored, and then click Ignore Alarm.
Step 2: When the operation confirmation box appears, click OK.
Step 3: After successfully ignoring the alarm, click X to close the prompt box and complete the operation.
To clear the alarm in the list:
Step 1: Click the 
in the Action column of the alarm to be cleared.
Step 2: When the confirmation box appears, click OK.
Step 3: After successfully clearing the alarm, click X to close the prompt box and complete the operation.
