7. Alarm Configuration
When properly configured, VMR and NPS units can monitor rack temperature, ping
command response and other factors at network installation sites. In addition to the
monitoring abilities listed above, VMR series units can also measure and record current,
power and voltage conditions. Note however that NPS units do not support current
consumption, power and voltage monitoring functions.
If user defined trigger levels for temperature are exceeded, the VMR/NPS can also
perform load shedding; automatically shutting off user-designated power outlets in
order to reduce the amount of heat generated in the rack. When temperatures return to
acceptable levels, the VMR/NPS can then switch outlets back on again. The VMR (but
not the NPS) can also perform load shedding when current consumption rises above
user-defined threshold values. When any of the user-defined alarms are triggered,
the VMR/NPS can send an alarm message to the proper personnel via Email, Syslog
Message or SNMP trap.
This section describes the procedure for setting up the VMR/NPS to send alarm
messages when critical situations are detected. For instructions regarding configuration
of the Log function, please refer to Section 5.3.3.
Notes:
• Current and Power Monitoring features are not available on NPS units.
• 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 VMR/NPS Alarm functions, access the command mode using a
password that allows Administrator level commands and then activate the Alarm
Configuration menu (in the Text Interface, type /AC and press [Enter]; in the Web
Browser Interface, click on the "Alarm Configuration" link.)
