2 The Omni Switch/Router MPX

Omni Switch/Router Management Processor Module

(MPX) Features

The MPX provides such system services as maintenance of user configuration information,
downloading of switching module software, basic bridge management functions, basic rout-
ing functions, the SNMP management agent, access to the User Interface software, and
Advanced Routing. In addition, the MPX can operate in a redundant configuration with
another MPX.
Important Note
If you have a single MPX in your chassis, it must be
installed in Slot 1.
With the optional HRE-X, which is described in Chapter 1, “Omni Switch/Router Chassis and
Power Supplies,” you can increase routing performance to 1.5 million packets per second.
Warning
Do not install any version of the MPM (i.e, MPM-C,
MPM-1G, MPM-II, MPM-III, or original MPM) in a chassis
with an MPX or any OmniSwitch switching module.
Installing an MPM in a chassis with an MPX can cause
physical damage.
