Introduction

This chapter introduces the 6H308-24 and 6H308-48 Fast Ethernet switching modules.

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.

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.
