1 Introduction This chapter introduces the 6H352-25 Fast Ethernet switching module. Important Notice 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.
Figure 1-1 The 6H352-25 Module FAST ENET 6H352-25 RESET COM 1X CPU GROUP SELECT G R O U P GROUP GROUP 1 11X 13X G R O U P 2 23X 3547_01 1-2 Introduction
Connectivity 1.1 CONNECTIVITY The 6H352-25 connects to Ethernet networks or workstations through the front panel connectors. The ports support Unshielded Twisted Pair (UTP) cables with an impedance between 85 and 111 ohms at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T and 100BASE-TX compliant. 1.2 OPTIONAL HSIMs AND VHSIMs Optional HSIMs and VHSIMs are available from Enterasys Networks for additional connectivity to various networking technologies.
Half-Duplex/Full-Duplex Auto-Negotiation 1.4 HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION The fixed front panel ports on the 6H352-25 have the ability to auto-negotiate the ports’ mode of operation (half-duplex or full-duplex) between two devices according to the 802.3x standard. During Auto-Negotiation, two devices automatically exchange information “telling” each other their current operating mode. The Auto-Negotiation feature targets the maximum capability that can be reached between the two devices.
Broadcast Suppression 1.7 BROADCAST SUPPRESSION Broadcast Suppression enables a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out the other ports on the module. Any broadcast frames above this specified limit are dropped. In the event that broadcast frames are being suppressed, multicast and unicast frames continue to be switched. 1.
Flow Control 1.10 FLOW CONTROL Flow control is a method of managing the flow of frames between two devices. It ensures that a transmitting device does not saturate a receiving device with data. This is accomplished by the transmitting device pausing its transmission while the receiving device processes the frames already received. The 6H352-25 supports the following two types of flow control: • Frame based 802.3x • Back pressure Frame based 802.
Distributed Chassis Management 1.13 DISTRIBUTED CHASSIS MANAGEMENT Installation in the MATRIX E7 Chassis From a management perspective, 6x3xx modules in the MATRIX E7 chassis can be managed separately by individual IP addresses. Any modules in the MATRIX E7 can be selected and managed, however, no overall system wide settings are available. NOTE: The MATRIX E7 chassis does not allow Distributed Chassis Management functionality as in the SmartSwitch 6000 chassis.
Standards Compatibility 1.16 STANDARDS COMPATIBILITY The 6H352-25 is fully compliant with the IEEE 802.3, 802.3u, 802.3x, 802.1D, and 802.1Q standards. The 6H352-25 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 6H352-25 supports a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery).
2 Network Requirements Before installing the 6H352-25, review the requirements and specifications referred to in this chapter concerning the following: • SmartTrunk (Section 2.1) • 10BASE-T Twisted Pair Network (Section 2.2) • 100BASE-T Twisted Pair Network (Section 2.3) The network installation must meet the requirements to ensure satisfactory performance of this equipment. Failure to do so will produce poor network performance.
100BASE-TX Network 2.3 100BASE-TX NETWORK The fixed front panel ports of the 6H352-25 provide a connection that supports Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u 100BASE-TX Fast Ethernet network requirements for the devices to operate at 100 Mbps.
