3.2Connecting Ethernet Media

The Black-Box LE14XXA-Series Fiber Switches are specifically designed t

support all standard Ethernet media types within a single Switch unit. This is

accomplished by using a family of 4-port Modules (4PMs) which can be individually

selected and configured per-port. See Section 2.4 for a description of the 4PMs.

The various media types supported along with the corresponding IEEE 802.3 and

802.3u standards and connector types are as follows:

3.2.1Connecting Fiber Optic ST-type, “twist-lock”

The following procedure applies to installations using a 4PM with ST -type fiber connectors. This procedure applies to ports using a LE1428C or LE1424C.

1.Before connecting the fiber optic cable, remove the protective dust caps from the tips o the connectors on the 4PM. Save these dust caps for future use.

2.Wipe clean the ends of the dual connectors with a soft cloth or lint -free lens tissue dampened in alcohol. Make certain the connectors are clean before connecting.

Note: One strand of the duplex fiber optic cable is coded using color bands at regular intervals; you must use the color-coded strand on the associated ports at each end of the fiber optic segment.

3.Connect the Transmit (TX) port (light colored post) on the 4PM to the Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for this first TX-to RX connection.

4.Connect the Receive (RX) port (dark colored post on the PM) to the Transmit (TX) po of the remote device. Use the non-color coded fiber strand for this.

5.The LINK LED on the front of the 4PM will illuminate when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit aft cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the 4PM connector to remedy this situation.
