7. Alarm Configuration
When properly configured, the MPC can meter current, temperature and voltage
readings, and log this information for future review. In addition, the MPC can also
generate alarms when current or temperature readings exceed user-defined trigger
levels, when input voltage is lost or restored to the unit, when a circuit breaker is open,
when communication with the AUX units is disrupted, when a Ping-No-Answer condition
is detected, and when the Invalid Access Lockout feature is triggered.
When any of these conditions are detected, the MPC can send an "Alarm" to the proper
personnel via Email, Syslog Message or SNMP trap. If the user-defined trigger levels
for temperature and current load are exceeded, the MPC 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 MPC can then restore power to the non-essential devices when temperature
and/or current load drop to user-defined acceptable levels.
This section describes the procedure for setting up the MPC to send alarm messages
when any of these critical situations are detected. For instructions regarding
configuration of the Log function, please refer to Section 5.3.4.
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 has been 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 has been 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.
To configure the MPC's Alarm functions, access the command mode using a password
that allows Administrator level commands and then proceed as follows:
• Text Interface: Type /AC and then press [Enter] to display the Alarm
Configuration Menu.
• Web Browser Interface: Click the "Alarm Configuration" link, located on the left
hand side of the screen to display the Alarm Configuration Menu.
