Connecting the ANH-8/DC to Other Repeaters/Hubs

You can use Port 1 in MDI configuration to connect to a 10Base-T MDI-X port on another router/hub/bridge device using UTP straight-through RJ-45 patch cables (instead of a special crossover cable). You can interconnect (daisychain) as many as four 8-Port ANH-8/DC or other hub systems.

To determine whether you need to use a crossover cable or straight-through cable to interconnect hub units, consider the following:

•If the Ethernet UTP ports on both hubs are in MDI mode, use a crossover cable.

•If the UTP ports on both hubs are in MDI-X mode, use a crossover cable.

•If the UTP port on one hub is in MDI mode, and the UTP port on the other hub is in MDI-X mode, use a straight-through cable.
