1. PRODUCT OVERVIEW Description This installation and user guide describes the Cabletron Systems ELS100-24TXM Ethernet switch. The switch is IEEE 802.1D-compliant and supports 24 IEEE 802.3u 100Base-TX Fast Ethernet ports. Each port can alternatively operate as an IEEE 802.3i 10Base-T port. In addition, two of the switch’s ports support Fast Ethernet over fiber (IEEE 802.3u 100Base-FX) when a modular daughtercard is installed. The Cabletron ELS100-24TXM switch automatically learns end-stati
