on the same port segment will be filtered, constraining them to that one port and relieving
the rest of the network from processing them. A packet whose destination address is on
another port segment will be forwarded to the appropriate port, and will not be sent to the
other ports where it is not needed. Traffic needed for maintaining the operation of the
network (such as occasional multi-cast packets) is forwarded to all ports.
The RFL 3000 4K-Series Switches operate in the store-and-forward switching
mode, which eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.
Address Learning
All
24-port
RFL 3000 4K-Series units have address table capacity of 2K node
addresses, suitable for use in large networks. They are self-learning, so that as nodes are
added or removed or moved from one port / segment to another, the 4K24 Switch
automatically keeps up with node locations.
An address-aging algorithm causes least-used addresses to fall out of the address
buffer in favor of new and frequently-used addresses. To reset the address buffer, cycle
power down-and-up.
4.2 Status
LEDs
For RFL 3000 4K24 models :
PWR :
Power LED, ON when external power is applied to the unit.
Link/Act :
Steady ON for link with no traffic, blinking indicates port is
transmitting and receiving.
Col/FDX :
Full / Half duplex LED, steady ON when the port is running full
duplex, blinking for half duplex collisions
100/10 :
Speed LED, ON when the speed is 100Mbps , OFF when the
speed is 10 Mbps

Uplink Port #1X for Cascading
Figure 4.3 : Up-link on RJ-45 Port#1X
RFL 3000 4K24’s each have one Up-link port, port # 1X, which can be used
when regular port #1 is not connected. The Up-link port allows non-node (switch-to-
repeater, switch-to-switch, etc.) connections without a special cross-over cable. It
works the same for 10Mb or 100Mb connections.
