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 PM 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 the cable is connected, the normal cause is improper cable polarity.  
Swap the fiber cables at the PM connector to try to remedy this situation. 
 
3.2.2 
Connecting Fiber Optic SC-type, "Snap-In" 
The following procedure applies to installations using a PM with SC-type fiber 
connectors, i.e., using 6K-MSC or 6K-SSC (single mode) etc. 
When connecting fiber media to SC connectors, simply snap the two square male 
connectors into the SC female jacks of the 6KPM until they click and are secure. 
 
3.2.3 Connecting 
Single-Mode Fiber Optic 
When using single-mode fiber cable, be sure to use single-mode fiber port 
connectors.  Single-mode fiber cable has a smaller diameter than multi-mode fiber cable 
(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx 
are the diameters of the core and the core plus the cladding respectively). Single-mode 
fiber allows full bandwidth at longer distances, and may be used to connect 10 Mb nodes 
up to 10 Km apart, or 18Km with the 6K-SSC. 
The same procedure for multi-mode fiber applies to single-mode fiber 
connectors.  Follow the steps listed in Section 3.2.2 above. 
 
3.2.4 
Connecting Twisted Pair (RJ-45,CAT3, CAT5, Unshielded or 
Shielded)
 
The RJ-45 ports of the Magnum 6K32F Series can be connected to the 
following two media types: 100BASE-TX and 10BASE-T.  CAT 5 cables should be used 
when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, 
CAT 3 may be used.  In either case, the maximum distance for unshielded twisted pair 
cabling is 100 meters (328 ft).

NOTE :   It is recommended that high quality CAT. 5 cables (which work for both 10 Mb 
and 100Mb) be used whenever possible in order to provide flexibility in a 
mixed-speed network, since dual-speed ports are auto-sensing for either 10 and 
100Mb/s.
  
  The following procedure describes how to connect a 10BASE-T or 100BASE-
TX twisted pair segment to the RJ-45 port. The procedure is the same for both 
unshielded and shielded twisted pair cables. 
1.    Using standard twisted pair media, insert either end of the cable with an RJ-45 
plug into the RJ-45 connector of the port. Note that, even though the connector is
