PWR          :  Power LED, ON when external power is applied to the unit.  

 

LK             :   Steady ON, Link status for 10 Mbps and 100Mbps operation.   
ACT          :  ON with port activity for 10 Mbps and 100Mbps operation.  

 

F/H            :  Full / Half duplex LED,  ON when the port is running full 

duplex, OFF for half duplex.  

100/10        : Speed LED, ON when the speed is 100Mbps , OFF when the     

speed is 10 Mbps  

The upper part of the copper port module has a manual Up-link switch, located 

on the inside of the unit on the port module board next to the RJ45 port # 1 which it 

controls.  It enables the port’s cable to be cascaded (X) to a 10/100Mb repeater or 

switching hub in the network. The manual Up-link switch position is configured as (=) 

position as default factory setting, where used for all-copper module or combo modules. 

Auto-Cross(MDIX) and Auto-negotiation, for RJ-45 ports 

 

The RJ-45 ports independently support auto-cross (MDI or MDIX) in 

auto-negotiation mode and will work properly with all the other connected devices 
with RJ-45 port whether it supports Auto-negotiation or not (e.g 10Mb Hub, media 
converter) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch). No 
cross-over cable is required while using the 6K8’s copper port to other devices. 
Operation is according to the IEEE 802.3u standard.  

The Managed 6K25-Series Fast Ethernet copper ports, 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 MNS software.  The factory default setting is for auto-negotiation.  

At 10Mb or 100Mb-fixed speed, the user may select half- or full-duplex mode by MNS 

Software for each RJ-45 port separately. For detail information See Section (10.1 at 

page no.52) of this manual to access the “6K-MNS(Rel 3) Software user guide” 

One frequently-used application for the Managed Magnum 6K25 Switch 

copper ports is to connect one of them using a fiber media converter to another Switch in 

the network backbone, or to some other remote 100Mb device.  In this case, it is 

desirable to operate the fiber link at 100Mb speed, and at either half- or full duplex mode 

depending on the capabilities of the remote device.  Standard commercially available 

Fast Ethernet media converters mostly do not support auto-negotiation properly, and 

require that the switched port to which they are connected be at 100Mb fixed speed.  

Attachment to 10/100 auto-negotiation ports typically will not work properly.  The 6K25
