Keep Alive Method to detect communication failure:
a. Ping is the only option in the
Protocol
field.
b. In the
IP Address
field, enter the IP address of this FXM.
c.
In the
Delay Between Retry
field, enter the delay between pings: minimum = 5 sec, maximum = 65535
sec.
How to detect communication failure:
a. In the
Timeout
field, enter the ping timeout. Minimum = 2 sec, Maximum = 65535 sec.
b. In the
Retries Before Failure
field, enter the number of pings to repeat before power cycling. Minimum =
1, Maximum = 20.
Keep Alive action to attempt to restore communication:
a. The
Action
field has 3 options: reset all power (AC and DC), reset AC power, and reset DC power. This
action resets the power for the duration set in Step b.
b. The
Action Duration
field is how long the output will be shut off by the UPS, Minimum = 5 sec, Maximum =
3600 sec.
When To Fail:
a. The
After X Consecutive Actions
field determines the number of times the UPS will go through the ping
and power down and back up cycle before registering an alarm for Keep Alive. Other alarms and events
will occur regardless of this value. After the final power cycle, the UPS will issue another ping after the
Delay between retry has elapsed. This ensures the destination IP is not alive. The UPS will then set the
Keep Alive alarm. Minimum = 1, Maximum = 20.
Keep Alive Failure:
a. The
Send Trap
field allows the email and SNMP trap notification to be switched on and off for the Keep
Alive only.
b. The
Delay to Re-Start-up
field configures the delay after the Keep Alive alarm is set and the next ping is
sent in delay to restart. Minimum = 5 sec, Maximum = 3600 sec.
Operation of the Keep Alive Feature
When [Status] is [On], the feature is enabled as follows:
1. Wait for [Delay To Start-up] seconds and ping the [IP Address] every [Delay Between Retry] seconds.
2. When a ping fails, wait for [Timeout] seconds before doing another ping. If the ping still fails, repeat this
process [Retries Before Failure] times.
3. After retrying for [Retries Before Failure] times and pinging still fails, perform the selected [Action] for
[Action Duration] seconds.
4. Wait for [Delay Between Retry] seconds before pinging again.
5. If the ping still fails, repeat the last three points (3-5) for [After X Consecutive Actions] times.
6. If the ping still fails, activate the Keep Alive alarm and if [Send Trap] is [On], send a trap. The unit then
waits for [Delay To Re-Start-up] to start the whole thing again.
