Product Description
Overview
This chapter describes the features of the AT-FH700 Series of stackable dual-speed Fast Ethernet hubs:
!AT-FH708SW
!AT-FH712SW
!AT-FH716SW
!AT-FH724SW
!AT-FH716
The AT-FH700 Series hubs were designed to provide a compact, flexible solution for corporate workgroups or small and medium businesses. These hubs provide 8, 12, 16 and 24 dual-speed ports (10/100 Mbps). The hubs contain two internal repeater buses: one for 10 Mbps traffic and another for 100 Mbps traffic.
The AT-FH708SW, AT-FH712SW, AT-FH716SW and AT-FH724SW hubs include an integrated two-port switch module that connects the 10 Mbps and 100 Mbps repeater buses. The switch module allows communications between devices operating at different speeds.
On the AT-FH716 model, traffic between connected devices of the same speed are confined within the appropriate repeater bus. Each of these ports automatically senses the speed of the attached device, and channels the data to the appropriate 10 Mbps or 100 Mbps segment.
