Magnum Quad-Series Fiber Switches Installation and User Guide (06/03)
3.2 Connecting Ethernet Media
The Magnum Quad-Series Fiber Switches are specifically designed
to support all standard Ethernet media types within a single Switch unit. This
is accomplished by using a family of Quad-port Modules (QPMs) which can be
individually selected and configured per-port. See Section 2.4 for a description
of the QPMs.
The various media types supported along with the corresponding IEEE
802.3 and 802.3u standards and connector types are as follows:

3.2.1 Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a QPM with ST-type fiber
connectors. This procedure applies to ports using a QPM-MST or QPM10-MST.
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the QPM. 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 QPM 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 QPM 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 QPM connector to remedy this situation.
