Connecting BayStack AN and ANH Systems to a Network

C-6

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.

igure 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 Starting BayStack 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.
