CHAPTER 1 INTRODUCTION Welcome to the 2H23-50R/2H33-37R SmartSwitch 2100 User’s Guide. This guide provides the necessary documentation to install and operate the 2H23-50R and 2H33-37R SmartSwitch 2100 standalone devices and provides information concerning network requirements, installation, troubleshooting, and the use of Local Management. 1.1 USING THIS GUIDE Read through this guide completely to understand the 2H23-50R and 2H33-37R capabilities and Local Management functions.
Chapter 1: Introduction Appendix A, Specifications, contains information on functionality and operating specifications, connector pinouts, environmental requirements, and physical properties. Appendix B, FE-100TX, FE-100FX, and FE-100F3 Specifications, contains information about FE-100TX pinouts and information concerning cable types used with the FE-100FX and FE-100F3.
Overview The 2H23-50R is a high speed network repeater/switch device that provides four Ethernet networks and four Fast Ethernet networks (RJ21 MicroLANs, CONN 1 through CONN 4) and two slots (5 and 6) for optional Fast Ethernet Interface Modules. The RJ21 connectors each consist of 12 repeater ports that are able to reside on the Ethernet (10 Mbps) or the Fast Ethernet (100 Mbps) network. Each Ethernet and Fast Ethernet network supports 802.
Chapter 1: Introduction 1.3.1 Connectivity The 2H23-50R or 2H33-37R connect to Ethernet/Fast Ethernet networks or workstations through RJ21 ports on the front panel. Each port supports a 25-pair cable at lengths up to 100 meters (each pair must be Category 5 compliant with an impedance of 85 to 111 ohms). The ports are IEEE 802.3 10BASE-T and IEEE 802.3u 100BASE-T compliant.
Overview When Auto-Negotiation is supported at both ends of a link, the two devices dynamically adjust to full or half duplex operation based on the maximum capability that can be reached between the two devices. If the device connected to the FE-100TX cannot auto-negotiate, the FE-100TX Fast Ethernet Interface Module operates according to the capabilities of the other device. 1.3.
Chapter 1: Introduction The RAD requests start out at an interval of 1 second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a server, or an IP address is entered using Local Management. 1.3.6 Management Management of the 2H23-50R or 2H33-37R is accomplished using SNMP compliant management tools for in-band Local Management.
Optional Features 1.3.8 Standards Compatibility The 2H23-50R provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2H23-50R also supports 100BASE-TX and 100BASE-FX Fast Ethernet standards and a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1317 (RS232 MIB), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB).
