2-6 Installing the System

Making a Connection via the MDI Daisy-Chain Port

The Fast EtherHub 3500 hubs

are Class I repeaters. Class I

repeaters cannot be cascaded

to another repeater in the same

collision domain.

The daisy-chain port can only

be cascaded to another device

which breaks up the collision

domain (e.g., an Ethernet

switch).

Stackable Fast Ethernet hubs are generally restricted to Class I

repeater types due to the timing requirements for passing traffic

and management data across the stack’s backplane. Although

Class I repeaters cannot be cascaded to another device in the

same collision domain via the daisy-chain port, more powerful

interconnection options are provided via the hub’s backplane

and optional SmartExtender Modules.

The daisy-chain port can only be cascaded to another device

which breaks up the collision domain (e.g., an Ethernet switch).

Prepare straight-through 100W Category 5 shielded or

unshielded twisted-pair cables with RJ-45 plugs at both ends.

Connect one end of the cable to the 12MDI port on this hub,

and the other end to a standard MDI-X station port on the other

device. Remember that when using the daisy-chain port

(12MDI), station port (12MDI-X) cannot be used. When inserting

an RJ-45 plug, be sure the tab on the plug clicks into position

to ensure that it is properly seated.

Notes: 1. Make sure the twisted-pair cable does not exceed 100 meters.

2. To connect to a switch, you may also run straight-through twisted-

pair cabling from a station port on this hub to a crossover port on

the switch. However, if you must connect to a switch via station

ports at both ends of the cable, use crossover cabling.

Connecting to a SmartExtender Module

The Fast Ethernet 3500 Series includes a network expansion

slot on the front panel that supports connection to 100BASE-TX

(10BASE-T), 100BASE-T4 or 100BASE-FX. Each

SmartExtender Module acts as a two-port switch that can

forward and filter data frames at line speed. One port is

connected to the hub’s internal repeater bus, while the other

port (on the hub’s front panel) can be used to connect the hub to

any compatible network device. The optional extender modules

include:
