Clock module on 9140

Question

Hello,
My switch is MDS9140. Here is the 'show envir' result:
`show environment`
Clock:
Clock Model Hw Status
A Clock Module -- not present/------
B Clock Module -- not present/------
IS my switch ok? Does it should have a clock module? Can anybody tell me that?
And I met some problems on MDS interfaces. I follow the guidance to do some 'show hardware internal fc-mac ...' command. Can anybody tell me where I can find command reference of these commands?
Thanks a lot.
Regards,
Sha

HI Nisha..
You can ensure that a PAI module is only called when a
certain condition applies by using the following
statement:
<b>FIELD <f> MODULE <mod> ON INPUT|REQUEST|*-INPUT.</b>
The additions have the following effects:
<b>ON INPUT</b>
The ABAP module is called only if the field contains a
value other than its initial value. This initial value is
determined by the data type of the field: Space for
character fields, zero for numeric fields. Even if the
user enters the initial value of the screen as the
initial value, the module is not called. (ON REQUEST, on
the other hand, does trigger the call in this case.)
<b>ON REQUEST</b>
The module <mod> is only called if the user has entered
something in the field. This includes cases when the user
overwrites an existing value with the same value, or
explicitly enters the initial value.
In general, the <b>ON REQUEST</b> condition is triggered
through any form of "manual input". As well as user
input, the following additional methods of entering
values also call the module:
The element attribute PARAMETER-ID (SPA/GPA parameters).
The element attribute HOLD DATA
CALL TRANSACTION ... USING
Automatic settings of particular global fields
ON *-INPUT
The ABAP module is called if the user has entered a "*"
in the first character of the field, and the field has
the attribute *-entry in the Screen Painter. When the
input field is passed to the program, the * is removed. *
behaves like an initial field in the ON INPUT condition.
