 II Baseline Dual Speed Hub is an easy-to-use, 

10/100 autosensing Class II hub (repeater). It is ideal for users who 
want to connect both Ethernet and Fast Ethernet devices 
(workstations and other equipment) to the same hub.

All ports on the Baseline Dual Speed Hub are half duplex, 
autosensing 10 Mbps and 100 Mbps. Each port senses the speed of 
the connected equipment and operates at the appropriate speed.

The Baseline Dual Speed Hub comes with:

One power cord for use with the Baseline Dual Speed Hub

Four full height and two reduced height, self-adhesive rubber 
pads

One rack mounting kit

A Registration Card and Envelope for you to fill in and return

The Baseline Dual Speed Hub is suitable for office use where it can 
be free standing or rack-mounted (in a wiring closet or equipment 
room). The hub can be powered either from the AC mains supply, or 
through an optional 3Com

Network Connections

The Baseline Dual Speed Hub has 12 or 24 shielded RJ-45, 10/100 
autosensing ports on the front panel. Each port can be connected to 
either a 10BASE-T (Ethernet) or a 100BASE-TX (Fast Ethernet) device. 

Internally, the hub has two repeater segments (10 Mbps and 
100 Mbps) which are linked by a switch, allowing connected 
10 Mbps and 100 Mbps devices to communicate.

You can connect a 10BASE-T or 100BASE-TX hub or switch to the 
Baseline Dual Speed Hub.
