Upon selecting a subordinate component, such as the
"Liquid Cooling Package", the following configuration
options are available:
– Group box Real Device
• Access Rights
• Alarm Configuration
These configuration options are described in detail in
the assembly and operating instructions of the
CMC III PU.

Tasks
The status of all connected components may be
polled and logically interlinked using Tasks. The
meanings of all statuses are described under the set-
ting options for the individual components (see
section 9.5 "Observation index tab"). Additionally,
date values may also be incorporated into the links. In
the event of a status change to the so-called trigger
expression, various actions may then be activated.
For example, in the event of an alarm message from
the integrated access sensor on a certain day of the
week, a corresponding e-mail may be sent. The cur-
rent status of a task cannot be polled via SNMP.
Tasks have general validity. For this reason, the infor-
mation displayed on the
Tasks
index tab is independ-
ent from the components selected in the left-hand
section of the screen.
Manual settings e.g. regarding the operating mode of
the fans may be overwritten by actions triggered in the
event of status changes.
Example:
You have defined a task whereby the fans
are switched off if the upper server inlet limit tempera-
ture is exceeded. To this end, the variable
Con-
fig.Fans.Command
is assigned the value
Off
if the
Temperature.Status
has a value of
Too High
("Value
on True"). Furthermore, the variable
Config.Fans.
Command
is assigned the value
Automatic
if the
Temperature.Status
does not have a value of
Too
High
("Value on False"). If the server inlet temperature
then drops back to within the preset limits after ex-
ceeding the upper limit, the fans are
always
switched
to automatic mode by the task, regardless of the pre-
viously selected fan operating mode (e.g. "Manual",
"Off" or "Full").
Note:
Further information on the creation of tasks
may be found in the assembly and operat-
ing instructions of the CMC III PU.
