(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.

One power cord for use with the Baseline Dual Speed Hub

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