• SysLog Configuration on Page 119
• SMTP Configuration on Page 120
Optionally, you can use the CLI for configuration, see Warnings (CLI) on Page 180.
Fault Relay
The ES8508 provides one alarm relay output (DO) that can support multiple fault conditions. The relay
contacts are energized (open) for normal operation and close under fault conditions. The fault conditions
include power failure, Ethernet port link faults, Ring topology changes, Ping failures, DI state changes or ping
remote IP address failure.
The Relay 1 field shows the current state of the relay. If the relay is triggered, the event type is marked with
an asterisk (*). The above image shows that a power event occurred.
The following table describes Fault Relay conditions:
Fault Relay
Power Detects power input status on DC1, DC2, or both power sources.
Port Link Monitors port link down events for the selected ports.
Ring Monitors ring topology changes.
Ping
If the target IP address does not reply to the ping request, the fault relay
is enabled.
Ping Reset
Pings target device and triggers the relay to emulate to emulate a power
reset on the remote device if the remote system crashes.
• IP Address: Remote device IP address whose power wiring is connected
with relay output.
• Reset Time (Sec): Duration that the relay contact is opened to emulate
the power switch is off. After the reset time, the relay closes to
emulate that the power switch is on.
• Hold Time (Sec): Boot time that the remote device requires. After the
relay contact closes the ES8508 starts pinging after the hold time.
