Switching, Address Learning
The Magnum S14-Series & PS14P(PoE) units have address table capacity of 2K
node addresses, and are suitable for use in large networks. They are self-learning, so that as
nodes are added or changed, the S14-Series & PS14P(PoE) automatically keeps up with
node locations.
An address-aging algorithm causes least-used addresses to fall out in favor of new
frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing
The RJ-45 ports 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 S14/PS14P(PoE)’s 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
