ELS100-8TXUF2.book Page xiii Friday, June 4, 1999 4:01 PM PREFACE Purpose This guide provides information about the features and applications of the Cabletron ELS100-8TXUF2 switch.
ELS100-8TXUF2.book Page xiv Friday, June 4, 1999 4:01 PM Appendix B. Flow Control: Describes how the flow control features are used to provide a mechanism for protecting the switch from overload conditions and to keep additional traffic off the network. Appendix C. Acronyms and Abbreviations: Provides definitions for a list of common acronyms and abbreviations used within the user guide and the networking industry.
ELS100-8TXUF2.book Page 1 Friday, June 4, 1999 4:01 PM 1. PRODUCT OVERVIEW Description This installation and user guide describes the Cabletron Systems ELS100-8TXUF2 Ethernet switch. This unit is IEEE 802.1D bridging compliant, and supports eight IEEE 802.3u 100Base-TX Fast Ethernet ports. Each of the RJ-45 ports can alternatively operate as an IEEE 802.3i 10Base-T port. In addition, the switch also includes one port that supports Fast Ethernet over fiber (IEEE 802.3u 100Base-FX).
ELS100-8TXUF2.book Page 2 Friday, June 4, 1999 4:01 PM - IEEE 802.3u auto-negotiation for full/half duplex and 10/100 Mbps speed operation on all RJ-45 10/100 ports - High performance store-and-forward switching • Performance Forwarding and Filtering: - at 10 Mbps, 14,880 packets-per-second (64 byte packets) - at 100 Mbps, 148,800 packets-per-second (64 byte packets) • Traffic Management: - Flow control per port: IEEE 802.
ELS100-8TXUF2.book Page 3 Friday, June 4, 1999 4:01 PM Figure 1-2 shows the port Link, Speed and Collision LEDs. The port LEDs are grouped to the left of their corresponding RJ-45 ports. Table 1-2 defines the performance of the port LEDs. Figure 1-2. Port LEDs Table 1-2. Port LEDs Defined LED Function Link LED On: Indicates a valid connection (link) on the associated port. Off: Indicates no link on the associated port. 100 LED On: Indicates the port is in the 100Base-TX mode.
ELS100-8TXUF2.book Page 4 Friday, June 4, 1999 4:01 PM Feature Summaries The following summaries provide a brief description of ELS100-8TXUF2 features in areas such as standards compliance, functionality, performance, and options. IEEE 802.1D Bridge The ELS100-8TXUF2 switch is fully compliant with IEEE 802.1D transparent bridging specifications. An aggregate address table containing 1K address entries is provided for learning, filtering, and forwarding. Addresses are automatically learned by the switch.
ELS100-8TXUF2.book Page 5 Friday, June 4, 1999 4:01 PM A broadcast cutoff threshold rate has been set in the switch for the forwarding of broadcast and unknown destination address packets. If the cutoff rate is exceeded, further packets of these types are dropped. This capability helps to alleviate broadcast storms, a problem often encountered in Ethernet networks. LEDs The switch port LEDs provide a quick and accurate display of the status of switch connections.
ELS100-8TXUF2.book Page 6 Friday, June 4, 1999 4:01 PM Client/Server Network Application To improve workstation performance in a client/server environment, the ELS100-8TXUF2 switch can be configured to provide 200 Mbps full duplex Fast Ethernet connections to servers by connecting each to a dedicated switch port (Figure 1-4). Users can be accommodated through connections to hubs, both at 10Mbps and 100Mbps speeds, through 10Mbps switches with 100Mbps uplinks, or through direct connections.
ELS100-8TXUF2.book Page 7 Friday, June 4, 1999 4:01 PM 2. INSTALLATION Inspecting Your Shipment When you receive the shipment of your switch, check the package contents and make sure you have the following items: • ELS100-8TXUF2 Fast Ethernet switch • Mounting velcro • Rubber feet • Power adapter • This document Site Requirements Before you install the switch, make sure the site meets the following requirements: 9033029 • Mounting Provide a flat table, wall or shelf surface.
ELS100-8TXUF2.book Page 8 Friday, June 4, 1999 4:01 PM Mounting the Switch on a Table or Shelf First attach the rubber feet to the indentations on the bottom of the switch. Then mount the switch on a table or shelf in a position that allows access to the front panel RJ-45 ports, visibility of the port LEDs, and access to the power cord. Make sure that the mounting surface can safely support the switch and that there is adequate space around the switch for ventilation and cooling.
ELS100-8TXUF2.book Page 9 Friday, June 4, 1999 4:01 PM Mounting the Switch on a Wall The module ships with one (1) velcro strip. The velcro strip is used to attach the switch to the wall. Do not attach rubber feet to the switch when mounting the switch to the wall with velcro. Figure 2-1 illustrates two recommended orientations for wall mounting the switch. This figure also shows where to the position velcro on the switch. To attach velcro do the following: 1.
ELS100-8TXUF2.book Page 10 Friday, June 4, 1999 4:01 PM Powering the Switch To supply power to the switch, do the following: 1. Connect the power adapter to the switch and to a grounded threeprong wall outlet (Figure 2-2). Secure the power cord to the tiedown bracket on the back of the switch to prevent it from being accidentally disconnected from the switch. See Appendix A, “Power Adapter Set Requirements,” for more information regarding specific international power adapter requirements. Figure 2-2.

ELS100-8TXUF2.book Page 12 Friday, June 4, 1999 4:01 PM 10Base-T/100Base-TX Ports The 10Base-T/100Base-TX ports use RJ-45 connectors. Figure 2-3 shows an RJ-45 connector being inserted into a port. Figure 2-3. Inserting an RJ-45 Connector into a Port The 10Base-T/100Base-TX ports interface to UTP cabling for connection to 10Base-T or 100Base-TX network segments or end-stations. These UTP connections meet the requirements of ISO 8877, specified by 10Base-T, Section 14 of the IEEE 802.3 specification.
ELS100-8TXUF2.book Page 13 Friday, June 4, 1999 4:01 PM 100Base-FX Fiber Ports The 100Base-FX Fiber port uses SC connectors. Figure 2-4 shows an SC fiber connector being inserted into the fiber port on the ELS100-8TXUF2. Figure 2-4. Inserting a Dual SC Connector into a Port This port supports multi-mode 62.5/125mm fiber. The 100Base-FX port uses SC fiber connectors. The SC fiber connectors are configured as a receive (RX)/and transmit(TX) pair.
