Magnum Quad-Series Fiber Switches Installation and User Guide (06/03)

3.2Connecting 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:

IEEE Standard	Media Type	Max. Distance	Port Module
Fiber:	mm1 Fiber	2.0km (6,562 ft)
100BASE-FX			QPM-MSC, -MST
	sgl.m2 Fiber	18.0km (95K ft)	QPM-SSC
small form factor	mm1 Fiber	2.0km (6,562 ft)	QPM-MTRJ, -MV45
10BASE-FL	mm1 Fiber	2.0km(6,562 ft)	QPM10-FST

Copper:
10BASE-T & 100BASE-TX twisted pair 100m (328 ft)		QPM-RJ45
1 mm = multi-mode	2 sgl.m = single-mode

3.2.1Connecting 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.
