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.) When the function is On , the Current column displays the status:
• Startup Delay
• Pinging
• Ping Echo Received
• Timeout total_number_of_retries/current_retry_number
• Reset total_number_of_retries/current_retry_number
• Reset Complete
• Failure
• Failure: Startup Delay
• Failure: Pinging
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 sec, Maximum = 3600 sec.
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 Alpha Micro 100.
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. DC reset occurs when one dry contact is set to LVD .
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 s, Maximum = 3600 s.
