MTRJ connectors.  Single-mode 100Mbps models are available with SC connectors and 

“Long-reach” for extra (up to 40 Km) long distance.  

The 100Mb fiber port modules on the Magnum 4K16-series normally are set 

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

On the Magnum 4K16 fiber series switches, the user may select full- or half-duplex 

mode per-port with a manual switch (F-H) located underneath the fiber ports  (See 

Section 3.4) for the flexibility to adapt to any type of Fast Ethernet devices.  

For Magnum fiber FKMs, there are LED’s  mounted on the front of the chassis 

labeled as port 8F and 9F. The Link (L/A) LED indicates ON with Link enabled, 

blinking for RX port activity, and F/H indicates steady for full duplex and OFF for half 

duplex. A fiber cable must be connected to each 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 LK LEDs to 

provide valid indications of operating conditions.  

4K16, 10/100 Dual-speed switched ports, RJ-45 (copper only)       

 

The Magnum 4K16 copper Series has 16 dual speed 10/100Mb switched RJ-45 

auto-negotiating 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. 

 There are three LED’s for each port.  The L/A (Link/Activity) steady ON for 

Link with no traffic and blinking indicates port is receiving and transmitting. The SPEED 

(10/100Mb) LED indicates operation at 100Mb speed when ON and at 10 Mb speed 

when OFF (when auto-negotiation is not disabled). The F/H LED is ON to indicate full-

duplex operation and OFF to indicate half-duplex mode and collisions. 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.
