Attach each hub to one of the backplane segments
Use the SmartExtender Module to interconnect different segments in the stack
Or interconnect the stack’s segments by attaching the daisy- chain port to a switch, or the station ports to a router
Attach to the extended network via the daisy-chain port
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.
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.
