rather than 100Mb speed.  It supports distances according to the 10Base-FL standard, i.e., 

2Km distance for multi-mode fiber.  (Single-mode for 10km distance may be available as 

a special order). 

Quad-Port Module, RJ-45 (copper)       

The Magnum Q-Series 

copper port module, model QPM-

RJ45, provides four 10/100Mb 

switched. RJ-45 ports. The 10/100Mb 

switched ports are independently N-

way 

auto-negotiating.

for operation at 10 or 100Mb speed in full- or half-duplex mode (as a default setting).  

They independently move to half-duplex mode at 10 Mb or at 100Mb speed if the device 

at the other end of the twisted pair cable is half-duplex or is not an auto-negotiating 

device. 

On the model QPM-RJ45 , there are four LED’s for each port.  The LK (Link) 

indicates “ready for operation” when lit. The ACT (Activity) 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 each RJ-45 10/100Mb port and a proper Link (LK lit) 

must be made with the device at the other end of the cable in order for the LEDs to 

provide valid indications of operating conditions.  

Internal jumper settings (See Section 3.4) allow technicians to over-ride the 

auto-negotiation feature and to manually set each port at full-duplex or half-duplex.  One 

port on each RJ-45 quad-port module is equipped with a Media Dependent Interface-

Crossover (MDI-X) push-button switch to simplify cascaded or up-link connections. 

Combo “3 + 1” Quad Port Modules, 3@RJ-45 and 1@fiber 

The combo quad-port modules are 

combination of copper and fiber media, 

available as three 10/100 switched RJ-45 

copper ports and one 100Mb switched multi-

mode fiber ST or SC or single mode SC-type port.             QPRJ-MSC
