n  100Mb switching services for large, high performance Ethernet LANs 

LE14XXA-Series Switches provide Fast Ethernet switching on all ports. They 

perform high speed filter/forward operations on the traffic, giving each port’s 

segment a full 100Mb (or 10 Mb) of bandwidth.  

n  Configurable with fiber ports, all connector types and speeds 

 

4-port modules are available with 100Mb mm ST, SC, VF-45, MTRJ single-mode 

SC, and 10 Mb ST-type connectors.  The configuration of the fiber ports, in the 

factory or in the field, allows the LE14XXA-Series Switches to adapt to mixed 

and changing fiber types in any application. 

 

n  Configurable with RJ-45 (copper) ports, 10/100 auto-negotiation 

RJ-45 4-port modules provide twisted pair segment connections, with N-way 

auto-negotiation or with manual speed and mode settings per port 

n  Mixed-media configurations for maximum flexibility 

Combinations of port module types can be configured in the same unit, adapting 

the LE14XXA-Series Switches to varying quantities and types of fiber vs. copper 

media. Port module changes can even be done in the field. 

n  Full-duplex or Half-duplex operation, auto-sensing 

 

All fiber and RJ-45 (copper) ports are capable of half- or full-duplex, individually 

selected. All RJ-45 ports support 10/100 auto-negotiation, or can be user-selected 

for the desired operating mode and speed.  

n  16-port, 12-port, 8-port and 4-port models  

 

With two chassis sizes (16-port and 8-port) configurable with 4-port 4PMs, 

capacity options complement the mixed-media configurability. 

n  Plug-and-Play installation for high performance switching 

 

 

Black Box LE14XXA-Series Switches are self-learning for node addresses. 

 

        They can be placed into operation without complex set-up procedures, even in 

 

 

large networks.  They operate transparent to system software. 

 

n  Front-mounted LEDs, world-wide AC power supply 

Front panel LED’s on each 4-port module display the status of each  

 

 

port for easy monitoring. An internal auto-ranging AC power supply  

 

 

allows LE14XXA Series Switches to be used throughout the world. (A 48VDC 

 

        power supply is optional, see Appendix B).
