Introduction
This chapter introduces the 6H352-25 Fast Ethernet switching module.
Depending on the firmware version used in the 6H352-25, some features described in this document may not be supported. Refer to the Release Notes shipped with the 6H352-25 to determine which features are supported.
The 6H352-25 module (Figure 1-1) features 24 10BASE-T/100BASE-TX switched ports connected via 24 RJ45 front panel connectors, and one High Speed Interface Module connector that allows an optional HSIM or VHSIM to be installed in the module for connections to high speed services.
Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of operation, as determined by auto-negotiation. Speed (10/100) or duplex can also be manually configured.
The 6H352-25 is a high-speed network switching module that supports IEEE 802.1D switching (bridging). Distributed Chassis Management (DCM) and functionality is not supported when the module is installed in the MATRIX E7. However, DCM is supported when the 6H352-25 module is installed in the SmartSwitch 6000 chassis.
The 6H352-25 ports can be configured to control traffic in several ways, including prioritizing traffic flow according to protocol type. The 6H352-25 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 6H352-25 receives power and backplane connectivity when it is inserted into an Enterasys Networks MATRIX E7 or SmartSwitch 6000 chassis.
