3.4.3. Management Processor
The GES provides an ARM 9 processor running at 96MHz for both internal and customer
specified functions. This processor is in-band allowing control by any device on the
Ethernet network that is connected to the GES.
This processor is lightly loaded after initialization of the GES allowing customer specified
functions to use most of the available processing power if required.
