Magnum 6K32F/FR/FC/FRC Managed Switch Installation and User Guide (05/08)
4.2
Status LEDs
For all Magnum 6K32F Series 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

Auto-Cross (MDIX)Auto-negotiation, for 10/100Mbps RJ-45 ports
The 32 RJ-45 ports on Magnum 6K32F Series support auto-cross (MDI or
MDIX) in the auto-negotiation mode according to the IEEE 802.3u standard. No
crossover cables are needed when connecting the 6K32F's 10/100 copper ports to other
unmanaged switches, legacy hubs, managed switches, media-converters etc. Please note
that there can be conditions with managed switches where the switch manager fixes the
port settings via software, and the result of the auto-negotiation is changed in the
managed switch by the manager commands. In such cases, the 10/100 speed or the F/H
mode may be affected, but auto-cross in the 6K32F Series Switches will still work. The
auto-cross function can be disabled, if fixed the port at 10 or 100Mb through software..
The Managed Magnum 6K32F Series Fast Ethernet copper ports can be set for
either fixed 100Mb speed or N-way auto-negotiation per the IEEE802.3u standard. The
selection is made via 6K-MNS software. The factory default setting is for auto-
negotiation. At 100Mb-fixed speed, the user may select half- or full-duplex mode by
6K-MNS Software for each RJ-45 port separately. For detail information see Section 9
(Port Setup) of Magnum 6K32F Software user guide (MNS-6K) . One frequently-
used application for the Managed 6K32F 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 6K32F Series 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.
