Alpha Technologies FXM 650, 1100, 2000 UPS - Manual (Page 57)

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-Startup 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 Startup] 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-Startup] to start the whole thing again.
