connection to another hub or switch typically.) When used for segments going to workstation

and other user node device connections, the MDI-X push-button should be in the OUT (=)

position.

The LE1425C will support 10BASE-T unshielded twisted pair wiring (UT

environments with maximum segment distances up to 100m (325 ft.), or shielded twisted pair

wiring (STP) of 150m (500 ft.). Each port has an Activity (ACT) LED indicating packets being

received, a Link (LK) LED that indicates proper connectivity with the remote device when lit, a

FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a “speed”

LED indicating 100Mb when lit (or 10 Mbps when off).

Important Note: For the LE1425C Crossover Push-button -

OUT for workstations and user connections.

IN for Up -Link connections to other hubs, etc.

The RJ-45 pins normally (TP crossover push-button DOWN) are per the standard for hubs-to-users twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit -, other pins not used. When the TP crossover push-button is UP, the pins of the RJ-45 po are per the standard for up -links using twisted pair wiring, i.e., the transmit and the receive pairs are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive-, other pins not used.

The LE1426C Combo 4-port

supports three auto-negotiating twisted pair

ports at 10/100Mbps FDX/HDX, and one

fiber port with 100Mbps multi-mode FX SC

connector. The three RJ-45 ports on the right

operate the same as those in the same place

on the QPM -RJ45 module.

The fiber SC connector functions as a fiber optics transceiver to support 100BASE-

FX network segments. When installed in a LE14XXA-Series Fiber Switches, it supports fiber

optic cable distances up the IEEE-standard 100Mbps distance limits, i.e., typically 2km at full-

duplex and 412m at half-duplex. The factory default setting is for full-duplex operation, and a

jumper on the module must be moved to select half-duplex. (See Section 3.4).
