Manual Switches for Up-link push-button, for RJ-45 Port#1 only 

The Magnum 4K8 Switch has a manual Up-link sliding switch, located on the 

front panel next to 10/100Mb RJ-45 port # 1 which it controls.  It enables the port’s cable 

to either connect to a user station node (push in) or to be cascaded (push out) to a 

10/100Mb repeater or switching hub in the network. Verify proper Up-link push-button 

position by noting Port 1’s LK (link) LED status, which is illuminated when a proper link 

is made. 

 

The Magnum 4K8 Switch has a manual sliding switch called “F-H” located on 

the front panel next to Fiber port # 9 which it controls.  While on “F” position enables the 

port # 9(Fiber port module) to full fixed 100Mbps only whereas in “H” position led the 

port#9 to set at half-duplex. 

The Magnum 4K-Series Fast Ethernet bonus copper port# 9 can be set for 

either fixed 100Mb speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u 

standard. The selection is made via an internal jumper.  The factory default setting  for 

RJ-45 port is auto-negotiation 

Auto-negotiation, for Fast Ethernet copper ports  

One frequently-used application for the Magnum 4K8-Switch copper ports is to 

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