4.2 Status LEDs
For Magnum 6K16-Series models (6K16/6K16V) :
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
4.3 Up-link Manual Switches set as (=) , for RJ-45 port only
The module has a manual Up-link switch, located on the inside of the board
next to the 10/100Mb (6K8-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 Up-link
Switch position is configured as (=) straight position by default from the factory settings
on all the RJ-45 ports, either used for all copper module or combo module.
4.4 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 6K16-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 6K16-Series 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
