6. Connect each hub to one of the 3 Fast Ethernet segments
embedded in the backplane bus using either on-board
configuration (Chapter 4) or optional network management
software (e.g., AccView/Open). You can leave a hub isolated
from the backplane if required for your network environment
(e.g., to restrict network access for the attached user group).
However, you should be careful to structure your network
connections so that nodes which communicate frequently are
located in the same segment. (Factory default is Segment 1.)

7. Bridge the different backplane segments in the Fast Ethernet
3500 stack by running a connection from the optional
100BASE-TX extender module on this hub to any station
port on another hub in the stack that has been assigned to a
different segment. Remember that devices connected to the
switching port exist in a separate segment (and unless also
connected to the FlexBus management channel) cannot be
controlled by a management agent in the stack. When
connecting a hub to the expansion port, the maximum cable
length is 100 meters.
Or interconnect the stack’

segments by attaching the daisy-
chain port to a switch, or the
station ports to a router
8. If you do not have any available SmartExtender Modules,
the different segments in a Fast EtherHub 3500 stack can
also be combined into an interconnected network by running
a cable from the hubs’ daisy-chain ports (i.e., using port
12MDI on hubs attached to the different segments) to a
network interconnection device such a switch; or by running
a cable from the hubs’ station ports (i.e., using ports on hubs
attached to different segments) to a router.

9. You can also attach the overall stack to a network intercon-
nection device via the daisy-chain port (when connecting to
a switch) or via a station port (when connecting to a router).
Run straight-through twisted-pair cable from the hub to the
other device. When attaching to a switch, run cable from the
MDI daisy-chain port on this hub to any (MDI-X) station
port on the switch (or vice versa).
Note: When using the 12MDI daisy-chain port, remember that port
12X cannot be used.
