Introduction
This chapter introduces the 6H308-24 and 6H308-48 Fast Ethernet switching modules.
The 6H308-24 module ( Figure 1-1 ) features 24 100BASE-FX switched ports connected via 24
MT-RJ fiber connectors. The 6H308-48 module ( Figure 1-1 ) features 48 100BASE-FX switched
ports connected via 48 MT-RJ fiber connectors.
Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of
operation, as determined by auto-negotiation. Full-duplex can also be manually configured.
Each module is a high-speed network switch that supports IEEE 802.1D switching (bridging).
Distributed Chassis Management (DCM) and SecureFast Switching (SFS) functionality is not
supported when the module is installed in the MATRIX E7. Both DCM and SFS are supported for
this module when it is installed in the 6C105 SmartSwitch 6000 chassis.
The module ports can be configured to control traffic in several ways, including prioritizing traffic
flow according to protocol type. The module can also be configured to establish 802.1Q Virtual
Local Area Networks (VLANs) and control the flow of frames associated with each VLAN
according to priority and Ether type. Detailed information about VLANs is provided in the
Enterasys Networks MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management
User’s Guide.
The module receives power and backplane connectivity when it is inserted into an Enterasys
Networks MATRIX E7 or 6C105 chassis.
Important Notice
Depending on the firmware version used in the module, some features described in this document
may not be supported. Refer to the Release Notes shipped with the module to determine which
features are supported.
