Switch Module (DFE-260S)

The DFE-260S switch module is used to allow interconnection between the

10Mbps and 100Mbps segments in the hub or hub stack.  Each hub stack

should have one DFE-260S module (such as the one included in the DFE-

2616x, DFE-2616ix, DFE-2624x or DFE-2624ix) to allow 10Mbps and

100Mbps stations to intercommunicate.  Note that the DFE-260S module

can only be installed in Slot 1 

–

 the center slot.  Also, the presence of

switch modules and their operational status can be viewed on the 

etwork

Monitoring – Bridge Information” screen.

NOTE:

In a stack containing a DFE-2616i, DFE-2624i,

DFE-2616ix, or DFE-2624ix intelligent master

hub, more than one DFE-260S switch module

may be used to provide increased reliability

through redundancy.  The software manage-

ment agent can control the DFE-260S

modules to provide link redundancy and pre-

vent network loops but only when multiple

modules are installed in hubs on the primary

master segment.

Fiber Optic Module (DFE-260FX)

The Fiber Optic module provides a standard Fast Ethernet 100BASE-FX

fiber optic connector.  A fiber optic connection of this kind is particularly

useful for creating a link between two DFE-2600 series hub stacks, placing

them in separate collision domains.  A link of this sort eliminates the need for

an external switch to divide stacks into separate domains.  Dividing the stacks

into separate collision domains overcomes the Fast Ethernet two-repeater

limitation, and effectively doubles overall bandwidth.

The Fiber Optic module includes the following LED indicators:
