Example 1 (Figure
Shows the chassis fully populated with DFE modules (7xxxxx). These modules communicate with
each other via the FTM2 chassis backplane and act as a single switching entity with one IP
address. The DFE modules are configured using a Command Line Interface set of commands.
Rule: DFE modules can be installed in any available chassis slot in the Matrix E7 chassis.
Example 2 (Figure
Shows the chassis fully populated with third generation modules (6x3xx). These modules can also
be installed in any available chassis slot in the Matrix E7 chassis, but operate as individual
modules with separate IP addresses. Each module is configured using Local Management.
Rule: The 6x3xx modules can be installed in any available chassis slot in the Matrix E7 chassis.
Example 3 (Figure
Shows chassis slots 1 through 5 populated with first and second generation modules (6x1xx and
6x2xx). If a 6x1xx or 6x2xx series module is installed in slot 6 or 7, it will operate in standalone
mode (no backplane connectivity). Like the 6x3xx modules, the 6x1xx and 6x2xx modules operate
as individual modules with separate IP addresses, and each one is configured using Local
Management.
Rule: The 6x1xx and 6x2xx modules can communicate with each other when they are installed in
chassis slots 1 through 5 in the Matrix E7 chassis. If installed in slot 6 or 7, they operate in
standalone mode.
Example 4 (Figure
Shows chassis slots 1 through 5 populated with a mix of 6x1xx, 6x2xx, and 6x3xx modules and
only third generation modules in slots 6 and 7.
In this module arrangement, the 6x3xx module provides a proxy bridge, which enables the 6x1xx
and 6x2xx modules to communicate with 6x3xx modules in slot 6 or 7. If more than one 6x3xx
module is installed in slots 1 to 5, the module in the lowest numbered slot performs the proxy
function for slots 6 and 7. Therefore, if a 6x3xx module is already performing the proxy function,
and another 6x3xx module is inserted into a lower numbered slot, connectivity will be temporarily
interrupted, as the new board takes over the proxy function. When a 6x3xx module in a lower
numbered slot is removed, and there is a 6x3xx module in a higher numbered slot, communication
is not interrupted.
For Local Management, plugging the Local Management connection into the 6x3xx modules will
allow management connections to all 6x1xx, 6x2xx, and 6x3xx modules. If the Local Management
connection is to a 6x1xx or 6x2xx board, only the modules in the first five slots will be recognized
by the management client.
Rule: There must be at least one 6x3xx module in slots 1 through 5 to enable communications
between the 6x1xx, 6x2xx, and 6x3xx modules.
