CHAPTER 1 INTRODUCTION Welcome to the 2E43-51/2E43-51R SmartSwitch 2100 User’s Guide. This guide provides the necessary documentation to install and operate the 2E43-51 and the 2E43-51R SmartSwitch 2100 devices and provides information concerning network requirements, installation, troubleshooting, and the use of Local Management. 1.1 USING THIS GUIDE Read through this guide to completely understand the 2E43-51 and 2E43-51R capabilities and Local Management functions.
Chapter 1: Introduction Chapter 5, Local Management, describes how to access and use Local Management to configure and manage the 2E43-51. 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.
2E43-51 Overview 1.3 2E43-51 OVERVIEW The 2E43-51 (Figure 1-1) is a repeater/switch device that provides four Ethernet networks (MicroLANs ENET 1 through 4), each consisting of 12 repeater ports that share a bandwidth of 10 Mbps. Each Ethernet network supports 802.1D switching (bridging), and Cabletron Systems SecureFast Switching Virtual Network technology.
Chapter 1: Introduction The 2E43-51R has two power supplies. The power supplies load share 50% (+/-5%) of the power required by the device. If one power supply fails, the remaining power supply assumes the entire load of the device without interruption to network traffic. Each power supply module supports its own ac input connection, which allows the user to connect each power supply to a different ac power circuit. 1.3.
2E43-51 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 BootP server, or an IP address is entered using Local Management. 1.3.6 Management Management of the 2E43-51 is accomplished using SNMP compliant management tools for in-band Local Management.
Optional Features 1.3.9 Year 2000 Compliant The 2E43-51 has an internal clock that can maintain the current time and date beyond the year 1999. 1.3.10 LANVIEW Diagnostic LEDs LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an easy way to observe the status of individual ports and overall network operations. 1.4 OPTIONAL FEATURES Options for the 2E43-51 include the following: • Fast Ethernet Interface Modules • High Speed Interface Modules 1.4.
