Logical architecture
As shown in
, the switch module contains three logical units:
•
CPU unit
—As the control and management core of the switch module, it is responsible for
module management, system configuration, and special packet processing.
•
AMC unit
—As the auxiliary management unit of the switch module, it is responsible for data
collection and report, power up/down control of the module, and system monitoring.
•
Switch unit
—As the data processing core of the switch module, it is responsible for internal
and external data forwarding and report of unrecognized packets.

Installation guidelines
Follow these guidelines when you install switch modules:
•
As shown in
, you can install a maximum of six switch modules in the enclosure.
•
The installation positions of switch modules and mezzanine network adapters must allow their
internal connections.
•
The six switch modules form three pairs with internal ports inter-connected: Slots 1 and 4 pair,
slots 2 and 5 pair, and slots 3 and 6 pair. Each pair can be used as a switching plane, and the
switch modules in each pair operate in active/standby mode.
•
The switch module can be hot swapped.
