The primary 

MPX

 has the ability to transfer files to and from the secondary 

MPX

. In the condi-

tion where the secondary 

MPX

 has an older version of software (Software Fallback), it is not 

desirable to update the configuration file of the secondary. It is therefore the default not to 
update the configuration file on the secondary if the secondary is running an earlier version 
of software. You can force the update using appropriate commands in the 

 menu. (See 

Chapter 6, “Configuring Management Processor Modules,” for more information on commands 
in the mpm menu.)

♦ Note ♦

Do not remove a primary 

MPX

 without performing a 

 command (described in Chapter 6, “Configur-

ing Management Processor Modules”) first.

A set of commands exists to monitor the primary and secondary 

MPX

s. These commands are 

covered in detail in Chapter 6, “Configuring Management Processor Modules.” Note that you 
can attach a terminal to both 

MPX

s in a chassis; however, you will see a different responses 

depending on which is primary and which is secondary. You should execute all 

UI

 

commands from the primary 

MPX

 except for those commands specifically addressing the 

secondary 

MPX

. For example, commands are available to control and monitor the secondary 

MPX

 from the primary 

MPX

 (e.g., the 

 command lists files on the secondary 

MPX

 from the 

primary 

MPX

).

Redundant

Both MPXs are running the same version of software
and the configurations are in sync.

Configuration Fallback

Both MPXs are running the same version of software
but the configurations are different.

Software Fallback

The MPXs are running different versions of software,
and their configurations may be the same or different.

None

There is only one MPX installed in the chassis.
