Description The 6H303-48 module features 48 10BASE-T/100BASE-TX switched ports connected through 4 RJ21 front panel 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 SmartSwitch module is a high-speed network switching module that supports IEEE 802.1D switching (bridging). Distributed Chassis Management (DCM) and SecureFast Switching (SFS) functionality is supported when the modules are installed in the 6C105 SmartSwitch 6000 chassis. The SmartSwitch module ports can be configured to control traffic in several ways, including prioritizing traffic flow according to protocol type. The SmartSwitch 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.
