LE1423C is a 4-port multi-mode fiber FX “small-form-factor” VF-45 connector used imarily in 100Mbps fiber-to-the-desktop links. Its size is similar to the MT-RJ port, but the
F-45 shell is slightly larger. When not in use, its appearance is distinctive because it has a tiny nged door over the port hole to act as a dust cover.
When installed in a LE14XXA-Series

The cable port is a “plug-in” connector, with
th fiber strands terminated in one housing that cannot be improperly inserted. The module is uipped with a LINK (LK) LED to indicate proper connectivity with the remote device, an CTIVITY (ACT) LED that flashes to show when Fast Ethernet packets are being received and (FDX/HDX) LED indicate the full-duplex mode when lit (or half-duplex when off).
2.6LE1425C (Twisted Pair), 10/100Mb TP 4-Port
The LE1425C module supports Ethernet twisted pair segments of any standard length. is equipped with 4-port RJ-45 connector with 10/100 and auto-negotiating capability on each ort. The RJ-45 connector is shielded to minimize emissions and will allow both unshielded isted pair (UTP) and shielded twisted pair (STP) cable connections.
The LE1425C 4-port module is equipped with a Media Dependent Interface- rossover (MDI-X) push-button to allow for one cascaded connections. This feature eliminates e need for a special twisted pair crossover
ble when connecting to a hub or another witch.
With the push-button in the IN (X)
sition, the PM -TP port is used for
scaded and up-link connections (i.e.: a | Cross-Over |
