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.

4.4Manual Switches “F-H”, for FPM Port#9 only

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
