Stacking Dual-Speed Hubs
These Dual-Speed Hubs provide an effective solution for combining Ethernet
and Fast Ethernet networks at a affordable price. Up to three units can be stacked
together, supporting up to either 24 or 48 users. To interconnect the 10 Mbps and
100 Mbps segments, just add an FDH-608 or FDH-616 unit to the stack. For criti-
cal applications, an additional hub that supports the switching function can be
included in the stack for backup purposes. However, a single Fast Ethernet Dual-
Speed Hub stack of only two units can easily meet the networking needs of most
small to medium-sized workgroups. As your workgroups gradually expand, just add
more hubs to your stack, or cascade to another hub or switch using ordinary
straight-through cable.
To make a hub-to-hub connection, do the following:
1. Locate the MII Port on the right side of the hub. After removing the protec-
tive cover, you will see two male socket ports available:
Note : The port that face upward is the Input Port
The port that face sideways is the Output Port
2. Make sure you have the proper cables:
¥ Use the MII Cable bundled with your FDH-608/FDH-616
3. Connect the MII Cable to the Output port of the first hub, then to the Input
port of the second hub (FDH-608 or FDH-616).
