1.3 6E12X-26 AND 6E13X-25 OVERVIEW
The 6E12X-26 and 6E13X-25, shown in Figure 1-1 , are interface
modules for Cabletron Systems 6C105 SmartSwitch 6000 chassis.
The 6E12X-26 and 6E13X-25 are high-speed network switch devices that
support 802.1D switching (bridging), 802.1Q switching, and Cabletron
Systems SecureFast Switching Virtual Network technology. Ports 25 and
26 of the 6E12X-26 support optional Fast Ethernet Interface Modules and
can provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet
networks. The 6E13X-25 is capable of being equipped with a High Speed
Interface Module (HSIM) that provides for additional connectivity to
other high speed networking technologies such as Asychronous Transfer
Mode (ATM), Wide Area Networks (WANs), Gigabit Ethernet and Fiber
Distributed Data Interface (FDDI).
The 6E12X-26 and 6E13X-25 can be used to connect individual
high-bandwidth user devices, such as workstations, and to provide a
central switching point for multiple Ethernet segments using devices such
as Cabletron Systems HubSTACK or other third party stackable devices.
NOTE
Figure 1-1 displays the 6E128-26 and 6E138-25. The
6E128-26 and the 6E129-26 are functionally identical, as are
the 6E138-25 and the 6E139-25. The only difference being that
the 6E129-26 and 6E139-25 modules support single mode
fiber optic cabling.
