Connecting Ethernet Media

The Magnum 4K8 Switches are specifically designed to support all
standard Ethernet media types within a single Switch unit. This is
accomplished by using a family of Fiber-port Modules (FPMs) which can be
individually selected and configured per-port. See Section 2.4 for a description
of the FPMs.
The various media types supported along with the corresponding IEEE
802.3 and 802.3u standards and connector types are as follows:
IEEE Standard
Fiber:
100BASE-FX
small form factor
10BASE-FL
Copper:
10BASE-T & 100BASE-TX twisted pair 100m (328 ft)

Connecting Fiber Optic ST-type, "twist-lock"

The following procedure applies to installations using a FPM with ST-type fiber
connectors. This procedure applies to ports using a FPM-MST or FPM10-MST.
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the FPM. 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 Magnum FPM 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) port of the remote device. Use the non-color coded fiber strand for this.
5. The LINK LED on the front of the FPM 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 after cable connection, the normal cause is
improper cable polarity. Swap the fiber cables at the FPM connector to
remedy this situation.
