4.1 Basic Mechanism
4.1.1.3 Business LAN
The business LAN is used for configuring the user's business system.
The following two methods are available for building a business LAN in an external
device:
- Mount a GSWB to use the switching hub function. Manage and operate the
GSWB by using the MMB Web-UI.
- Mount a 1000BASE-SX card or another card in a PCI slot of an IO_Unit, and
manage and operate the LAN independently.
The configuration of the business LAN is shown in
.
Figure 4.4 Business LAN
shows two GSWBs that are mounted to configure a business LAN. The
GSWB supports layer 2 switching hub functions including the tag VLAN function
and port VLAN function. In
, four 1-Gigabit LAN ports are provided for
each IO_Unit and two ports are connected to each GSWB.
The two GSWBs are connected to all IO_Units in a dual configuration.
One GSWB has eight 1-Gigabit LAN ports for LAN connection with external devices
outside the cabinet.
The GSWB specifications and general functions are described in
"Business LAN Management by GSWB."
