Introduction 1.5 OVERVIEW The SmartSTACK 100 ELS100-16TX is an intelligent Ethernet-to- Ethernet switch that is configured with 16 IEEE 802.3 10/100BASE-T autosensing Ethernet ports. The SmartSTACK 100 ELS100-16TX provides the option of substituting RJ45 ports 15 and 16 (either or both) with two EPIM ports. These ports accept the EPIM-100FX. The ELS100-16TX also includes an RS232C port for out-of-band management. Figure 1-1 shows the front panel for the SmartSTACK 100 ELS100-16TX.

Introduction ports allowing the switch port and an attached device to negotiate for full or half-duplex modes of operation. The SmartSTACK 100 ELS100-16TX also supports auto-negotiation as defined by IEEE 802.3u and will automatically set the port to the proper mode (10 Mbps, half/full duplex or, 100 Mbps half/full duplex). The EPIM100-FX interface will not support auto-negotiation, as auto negotiation for fiber is not defined in the 802.3u specification. Store and Forward Switching A
