Magnum 6K16V Managed Fiber Switch Installation and User Guide (06/04)
4.2 Status
LEDs
For all Magnum 6K16V models :
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 (=) 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-negotiation, for Fast Ethernet copper ports
The Managed Magnum 6K16V 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 8 (Optimizing Port usage) of Magnum 6K16V Software user guide (MNS) .
See Section (2.2.9 at page no.13) of this manual to access the “6K16V Software
userguide”
One frequently-used application for the Managed Magnum 6K16V 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
6K16V Switch’s RJ-45 ports handle this situation by configuring the ports as per desire
through MNS software port settings and can check the port status of each port after the
change.
