Fault Relay
Event Type: Link Failure
Link: Select the port ID that you want to monitor.
How to Configure: Select the check boxes of the Ethernet ports you want to monitor. You can select one or multiple ports.
When the selected ports are linked down or broken, the system will short Relay Output and light the Alarm LED.
Event Type: Ping Failure
IP Address: The IP address of the target device you want to ping.
Reset Time (Sec): Waiting time to short the relay output.
Hold Time (Sec): Waiting time to ping the target device for the duration of remote device boot
How to Configure: After selecting the Ping Failure event type, the system will turn Relay Output to the short state and
continuously ping the target device. When the ping failure occurs, the switch will turn the Relay Output to the open state for a
period of Reset Time.
After the Reset Time timeout, the system will turn the Relay Output to close state. After the Hold Time timer is timeout, the
switch system starts pinging the target device. For example: Reset Time is 5 sec, Hold Time is 50 sec.
If a ping failure occurs, the RocketLinx ES7528 will turn Relay output to the open state to emulate the power switch off for 5
second periods. After the Reset Time timeout, the RocketLinx ES7528 starts pinging the target device after 50 second periods.
The period time is for target device system rebooting. During the period, the RocketLinx ES7528 will not ping the target
device until the Hold Time times out.
