Features 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.
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).
