Magnum Quad-Series Fiber Switches 

Installation and User Guide (06/03) 

 

 

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:

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. 

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.
