An address-aging algorithm causes least-used addresses to fall out in favor of
frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Status LEDs
For all Magnum 6K32T & 6K32TRC 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 Auto-Cross (MDIX)Auto-negotiation, for 10/100Mbps RJ-45 ports
The 24 RJ-45 ports on Magnum 6K32T & 6K32TRC 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 6K32T & 6K32TRC’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
6K32T & 6K32TRC Switches will still work. The auto-cross function can be
disabled, if fixed the port at 10 or 100Mb through software..
The Managed Magnum 6K32T & 6K32TRC 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 7 (Port Setup) of Magnum 6K32T & 6K32TRC
Software user guide (MNS-6K) . One frequently-used application for the Managed
6K32T & 6K32TRC 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
