In an eight-port SFF fiber port module, all of the fiber ports are of the same 

speed (100Mb), mode, and connector type. Models are available with Small Form Factor 

(SFF) are multi-mode MT-RJ or LC-

type connectors, and single-mode 

LC-type connectors.  

The 100Mb fiber eight-

port modules for the Magnum 

6K25e’s normally are set (factory 

default) to operate in full-duplex mode for best fiber distance and performance. Using the 

6K25e’s  MNS software, the user may select full- or half-duplex mode per-port through 

set-up of the software (See Magnum 6K25e MNS Software Manual) for the flexibility to 

adapt to any FDX or HDX type of Fast Ethernet devices).  

There are three LED’s per fiber port. The Link (LK) LED indicates “ready for 

operation” on that port when lit, the F/H LED indicates operation in full-duplex mode 

when ON (half-duplex when OFF), and the blinking ACT LED indicates receiving 

Activity on the port. A fiber cable must be connected into a SFF 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. 

The 6K25e-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
