3Features and Benefits

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.

nConfigurable 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.

nConfigurable with RJ -45 (copper) ports, 10/100 auto-negotiation RJ-454-port modules provide twisted pair segment connections, with N-wayauto-negotiation or with manual speed and mode settings per port

nMixed-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.

nFull-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.

n16-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.

nPlug-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.

nFront-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).
