powered-up device at the other end of the cable) in order for a LK LED to 

provide valid indications of operating conditions on that port. 

 

The 6K8-Series’s 8-port Copper port module, model 6K8-RJ45, provides eight 

10/100Mb switched RJ-45 ports. The 10/100Mb switched ports normally (as a default 

setting) are independently N-way auto-negotiating, and auto-crossover (MDIX) for 

operation at 10 or 100Mb speed in full- or half-duplex mode, i.e., each independently 

selects a mode and speed to match the device at the other end of the twisted pair cable.  

 

 (See Section 4.3 for auto-negotiation and MDIX details). The auto-crossover feature will 

automatically determine the other side of connection to make the connection, and 

eliminate the need of crossover cable. 

On the model 6K8-RJ45 module, there are four LEDs for each port, two in the 

connector and two separate.  The LK (Link) LED indicates, “ready for operation” on that 

port when lit. The blinking ACT (Activity) LED indicates receiving Activity on that port 

when lit. The 10/100 LED 

indicates operation at 100Mb 

speed when ON and at 10 MB 

speed when OFF (when auto-

negotiation is not disabled). 

The FDX/HDX LED is ON to 

indicate full-duplex operation 

and OFF to indicate half-duplex mode. A twisted pair cable must be connected into an 

RJ-45 port and the Link (LK) indicator for that port must be ON (indicating there is a 

powered-up device at the other end of the cable) in order for a LK LED to provide valid 

indications of operating conditions on that port.

Using the 6K8-Series (MNS-6K) management software, the user may disable 

auto-negotiation and fix the desired operation of each RJ-45 port. User may select 10Mb 
or 100Mb speed and full- or half-duplex mode per-port as per user requirement. (See 
Magnum MNS-6K Software Manual for details info.).
