Keep Alive status/manual control:
a. The Status field allows the user to enable or disable the Keep Alive function. When disabled the alarm is
cleared.
b. The Delay to Startup field allows the user to set the time to the first ping from the enable ping or UPS
restart after a ping failure. Minimum = 5 s, Maximum = 3600 s.
Keep Alive Method to detect communication failure:
a. The Protocol field allows Ping as the only option.
b. The IP Address field is used to enter the IP address to be pinged.
c. The Delay Between Retry field is the delay between pings. Minimum = 5 s, Maximum = 65535 s.
How to detect communication failure:
a. The Timeout field is where the ping time out setting is configured. Minimum = 2 s, Maximum = 65534 s.
b. The Retries Before Failure field is 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 allows Reset Power as the only option.
b. The Action Duration field is how long the output will be shut off by the UPS, Minimum = 1, s
Maximum = 3600 s.
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 s, Maximum = 3600 s.
