Dual-Speed Stackable Hubs User’s Guide
Introduction
2
In the basic configuration, the 10Mbps and 100Mbps segments are separate
and do not intercommunicate. An optional DFE-260S switch module (in-
cluded with the DFE-2616x, DFE-2624x, DFE-2616ix, and DFE-2624ix) can
be installed in any hub in the stack, making it possible to transparently bridge
between the 10Mbps and 100Mbps segments. In a managed hub stack, more
than one DFE-260S module can be used to provide redundancy if the two
modules are both in the primary master hub segment..
Other add-in modules are also available, providing 100BASE-TX, or
100BASE-FX connections. DFE-2600 series hubs each have two slots for
accepting slide-in modules.
