PWR        :  Power LED, ON when external power is applied to the unit.  
L/A           :  Steady ON for link with no traffic, blinking indicates port is 

transmitting and receiving.   

 

F/H            : Full / Half duplex LED,  steady ON when the port is running full 

duplex, blinking for half duplex collisions  

Speed        : Speed LED, ON when the speed is 100Mbps , OFF when the     

speed is 10 Mbps. 

 

Magnum 4K16s each have one Up-link manual switch next to port #1 which it 

controls, can be used while cascading with other hub switch or any communicating 

device. The Up-link switch allows repeater-to-repeater connections without a special 

cross-over cable.  It works the same for 10Mb or 100Mb connections.   

Move sliding switch to  “=”  (or ports 2 thru 16) for straight-through 

twisted pair cabling from the 4K16 switched port to a user device, or to “X”  for 

cross-over or up-link segment connections from the first 4K16 port to a repeater or 

hub or switch. Verify proper port connection by noting the port’s LINK/ACT status, 

which is illuminated when a proper link is made and blinking when there is activity.

Auto-negotiation, for Fast Ethernet copper ports  

One frequently-used application for the Magnum 4K16 Switch copper ports is 

to connect one of them using a fiber media converter to another Switch in the network 

backbone, or to some other remote 100Mb device.  In this case, it is desirable to operate 

the fiber link at 100Mb speed, and at either half- or full duplex mode depending on the 

capabilities of the remote device.  Standard commercially-available Fast Ethernet media 

converters mostly do not support auto-negotiation properly, and require that the switched 

port to which they are connected be at 100Mb fixed speed.  Attachment to 10/100 auto-

negotiation ports typically will not work properly 

When 4K16 Switch’s RJ-45 copper ports are set for auto-negotiation and
