Connecting BayStack AN and ANH Systems to a Network
C-6 114074 Rev. A
Configuring Multiple Hubs
You can interconnect as many as four ANH units using the UTP repeater ports.
When you configure a network with multiple ANH (or other repeater/hub)
systems, you must comply with the following rules:
• Connect no more than four hubs.
• Make sure each UTP connection is no longer than 100 m.
• If a transceiver is connected to the AUI port, disable the SQE (signal quality
error) test function of the transceiver.
When connecting three or four hubs, make sure the installation complies with the
specifications in “Ensuring Ethernet Network Compliance” earlier in this chapter.
Figure C-2 shows an ANH linked with two Model 810M hubs. UTP patch cables
connect each MDI port to an MDI-X port. For information about activating the
MDI-X/MDI switch, see Installing and Operating BayStack AN and ANH
Systems.
Note: Backbone connections are usually made through the AUI port (see the
section “Configuring an AUI Port”).
Note: Minimize the number of repeaters between stations in the network by
connecting hubs in a star configuration. Avoid chaining hubs in a single line.
