CHAPTER 7: Alarm Configuration
101
7. Alarm Configuration
When properly congured, the Outlet Managed PDU can meter current, temperature
and voltage readings, and log this information for future review. In addition, the
Outlet Managed PDU can also generate alarms when current or temperature readings
exceed user-dened trigger levels, when input voltage is lost or restored to the unit,
when a circuit breaker is open (may not apply to all models,) when a Ping-No-
Answer condition is detected, when the Invalid Access Lockout feature is triggered
or when current consumption for a Plug or Plug Group rises too high or falls too low.
When any of these conditions are detected, the Outlet Managed PDU can send an
"Alarm" to the proper personnel via Email, Syslog Message or SNMP trap. If the
user-dened trigger levels for temperature and current load are exceeded, the Outlet
Managed PDU can also automatically shut off power to non-essential devices (Load
Shedding) in order to decrease current load and/or the amount of heat generated
within the rack. After Load Shedding has taken place, the Outlet Managed PDU can
then restore power to the non-essential devices when temperature and/or current load
drop to user-dened acceptable levels.
This section describes the procedure for setting up the Outlet Managed PDU to send
alarm messages when any of these critical situations are detected. For instructions
regarding conguration of the Log function, please refer to Section 5.3.3.
Notes:
• In order to send alarm notification via email, email addresses and
parameters must first be defined as described in Section 5.9.11.
Email alarm notification will then be sent for all alarms that are
enabled as described in this Section.
• In order to send alarm notification via Syslog Message, a Syslog
address must first be defined as described in Section 5.9.2. Once
the Syslog address has been defined, Syslog Messages will be
sent for every alarm that is discussed in this Section, providing
that the Trigger Enable parameter for the alarm is set to "On."
• In order to send alarm notification via SNMP Trap, SNMP Trap
parameters must first be defined as described in Section 5.9.7.
Once SNMP Trap Parameters have been defined, SNMP Traps will
be sent for every alarm that is discussed in this Section, providing
that the Trigger Enable parameter for the alarm is set to "On."
• When defining parameters via the Text Interface, make certain
to press the [Esc] key to completely exit from the configuration
menu and save newly defined parameters. When parameters are
defined via the Text Interface, newly defined parameters will not
be saved until the "Saving Configuration" message is displayed.
