Address Learning

All Magnum 6K32 units have address table capacities of 4K node addresses

suitable for use in larger networks. They are self-learning, so as nodes are added,

removed or moved from one segment to another, the 6K32 Switch automatically keeps

up with node locations.

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 6K32 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

Up-link Cross-over Switch on RJ-45 port modules, for port#1 only

The modular slot provided on Magnum 6K32 managed switch can be filled

with 6KP8-RJ45 port module among all the multiple choices of port modules. The upper

part of the copper port module (6KP8-RJ45) 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.

4.4

Auto-Cross (MDIX)Auto-negotiation, for 10/100Mbps RJ-45 ports

The 24 RJ-45 ports on Magnum 6K32 supports 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 6K32’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 6K32 Switches will still work. The

auto-cross function can be disabled, if fixed the port at 10 or 100Mb through

software..
