1 Introduction This chapter introduces the 6H302-48 and 6H303-48 Fast Ethernet 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. There are restrictions on the version of firmware required for 6H302-48 modules with a serial number starting with 3655xxxxxx.

Connectivity 1.1 CONNECTIVITY The module 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.
Remote Monitoring (RMON) SmartTrunk, also referred to as SmartTrunking, is Enterasys Networks’ terminology for load balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to provide additional throughput. The SmartTrunk application can be used with any of Enterasys Networks’ switch modules (except ATM modules).
Traffic Rate Limiting The VLAN redirect function is similar to the port redirect function except that the frames received by the module are redirected to a designated destination port according to the VLAN classification of the frames received. Multiple VLANs can be directed to the same destination port. The VLAN redirect function is only supported when the module is operating as an 802.1Q switch. 1.
GARP Switch Operation The module supports Frame based 802.3x flow control. Frame based 802.3x flow control is supported on all Ethernet ports operating in the full-duplex mode. Flow control can be enabled or disabled on a port-by-port basis. Back pressure flow control is not supported on ports operating in the half-duplex mode. 1.
Management Installation in the SmartSwitch 6000 (6C105) Chassis The SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its systems management functions are distributed to all modules, including the 6H302-48 or 6H303-48. The chassis can be managed using a single IP address, or the modules can be managed separately by individual IP addresses.
Standards Compatibility 1.15 STANDARDS COMPATIBILITY The 6H302-48 and 6H303-48 modules are fully compliant with the IEEE 802.3, 802.3u, 802.3x, 802.1D, and 802.1Q standards. The modules provide IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions.
2 Network Requirements Before installing the module, 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 module 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. Refer to the Cabling Guide for details. NOTE: The fixed ports of the module support Category 5 UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation.
3 Installation ELECTRICAL HAZARD: Only qualified personnel should install the module. NOTE: Read the Release Notes shipped with the module to check for any exceptions to the supported features and operation documented in this guide. This chapter provides the instructions to install the 6H302-48 or 6H303-48 module. A Phillips screwdriver is required to install options into the module. Follow the order of the sections listed below to correctly install the module. • Unpacking the Module (Section 3.
Unpacking the Module 3.1 UNPACKING THE MODULE Unpack the module as follows: 1. Open the box and remove the packing material protecting the module. 2.

B Mode Switch Bank Settings and Options This appendix covers the following items: • Required tools (Section B.1) • Locations, functions, and settings for the mode switches (Section B.2) • Upgrading the FLASH (Section B.3) B.1 REQUIRED TOOLS Use the following tools to perform the procedures provided in this appendix: • Antistatic wrist strap • Phillips screwdriver CAUTION: An antistatic wrist strap is required (provided with the module) to perform the procedures in this appendix.
Setting the Mode Switches B.2 SETTING THE MODE SWITCHES CAUTION: Read the appropriate sections to be fully aware of the consequences when changing switch settings. Only qualified personnel should change switch settings. Figure B-1 shows the location of the mode switches and the switch settings for normal operation. These switches are set at the factory and rarely need to be changed. Switch definitions and positions are as follows: • Switches 1 through 4 – For Enterasys Networks use only.
Setting the Mode Switches NOTE: After changing the position of Switch 6, DO NOT reapply power to the module until there is a station on the network acting as a BootP server, which contains the downloadable firmware image file. DO NOT attempt a Forced BootP unless a BootP server has been configured for the module. The BootP server references the location of a station acting as a Trivial File Transfer Protocol (TFTP) server containing the module image file.
FLASH Upgrade B.3 FLASH UPGRADE FLASH upgrade is available for the switch to expand from 8 to 16 MB. This section explains how to locate and add/replace the FLASH module.
