1 Introduction

Congratulations on your purchase of this rackmount stackable dual-speed hub. Migrating from traditional 10Mbps Ethernet to 100Mbps Fast Ethernet is now simple and affordable with these dual-speed hubs. These high performance 16-port, 24-Port, 32-port 10/100Mbps stackable dual- speed hubs are equipped with 16, 24, 32 RJ45 dual-speed ports, one uplink port and one internal 2-port switch.

Typically a dual-speed hub has two independent internal network segments: 10Mbps segment and 100Mbps segment. Depending on the speed of attached network devices, each individual port of a dual-speed hub provides Auto-Negotiation capability which automatically senses and selects optimum speed at 10Mbps or 100Mbps. A 10Mbps network device attached to the dual-speed hub will be able to communicate with other network devices attached to the hub running at 10Mbps. On the other hand,

a100Mbps network device attached to the dual-speed hub will be able to communicate with other devices attached to the hub running at 100Mbps. Therefore, dual-speed hub can be 10Base-T hub when all the connecting nodes are running at 10Mbps as illustrated in Figure 1-1, or can be 100Base-TX hub when all the connecting nodes are running at 100Mbps as illustrated in Figure 1-2. These stackable dual-speed hubs are the ideal hubs for both 10Base-T and 100Base-TX networks.
