Alarm Configuration
Address 1, 2, and 3: These parameters are used to select which of the three email
addresses, defined via the "Email Messages" menu (see Section 5.9.11,) will receive
the email alarm notification messages generated by this alarm. The Address
parameters can be used to select one, or any combination of the addresses defined
via the Email Messages menu. (Default = All On.)
Note: If Email addresses have been previously defined, then the text under the
parameters will list the current, user defined email addresses.
Subject: This parameter is used to define the text that will appear in the "Subject"
field for all email notification messages generated by this alarm. (Default = "Alarm:
Over Temperature (Initial)" or "Alarm: Over Temperature (Critical)".)
Load Shedding: Provides access to a submenu, which is used to configure and
enable the Load Shedding feature for the Over Temperature alarms. When Load
Shedding is enabled and properly configured, the RSM-8R4 will switch specific,
user-selected plugs On or Off whenever the temperature exceeds the Alarm
Set Threshold value. If the Auto Recovery feature is enabled, the RSM-8R4 can
also return these user-selected plugs to their prior status, when the temperature
falls below the Alarm Clear Threshold value. For more information on the Load
Shedding Feature and Auto Recovery, please refer to Section 7.1.1.
7.1.1. Over Temperature Alarms - Load Shedding and Auto Recovery
The Load Shedding feature is used to switch specific, user-defined plugs On or
Off whenever the temperature exceeds the Alarm Set Threshold value. This allows
the RSM-8R4 to automatically shut Off non-essential devices in order to reduce the
temperature generated within the rack, or automatically switch On devices such as fans
or cooling systems in order to dissipate heat from the rack. When the Auto Recovery
feature is enabled, the RSM-8R4 can also automatically "undo" the effects of the Load
Shedding feature when the temperature again falls to a user-defined non-critical level.
For both the Initial Threshold and Critical Threshold Over Temperature Alarms, Load
Shedding and Auto Recovery are enabled and configured via submenus of the Over
Temperature Alarm configuration screens. To access the Load Shedding and Auto
Recovery configuration menus, access the RSM-8R4 command mode using an account
that permits access to Administrator level commands, and then proceed as follows:
Text Interface: Access the Over Temperature Alarm configuration menu as
described in Section 7.1, and then type 5 and press [Enter] to display the Load
Shedding configuration.
Web Browser Interface: Access the Over temperature Alarm configuration menu
as described in Section 7.1, and then click on the "Load Shedding" link to display
the Load Shedding configuration menu.
Note that the Load Shedding configuration menus for both the Initial Threshold Alarm
and Critical Threshold Alarm offer essentially the same set of parameters, but the
parameters defined for each alarm are separate and unique. Therefore, parameters
defined for the Critical Threshold Load Shedding will not be applied to the Initial
Threshold Alarm and vice versa.
