Description Designed for customers who need a simple, affordable and scalable Fast Ethernet solution, Cabletron's SmartSTACK ELH100 Series consists of two modular and stackable dual-speed hubs which provide industry-standard 10 Mbps Ethernet and 100 Mbps Fast Ethernet connectivity to end stations, servers and other compatible devices. As the market for shared Ethernet moves from 10 Mbps to 10/100 Mbps to equip growing networks, the SmartSTACK ELH100 Series provides an ideal solution for upgrading your network to Fast Ethernet without replacing the existing infrastructure. The SmartSTACK ELH100-12/24/48TX provides 12, 24 or 48 ports of 10/100 shared Ethernet, an optional management module that supports SNMP/RMON and web agents, and optional modules that provide switched copper or fiber connections. Use the SmartSTACK Series to meet the needs of most users for common file transfer, or use the 100 Mbps bandwidth to relieve serious network congestion, run multimedia applications or satisfy power users.
