Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
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 Magnum DS60’s switched port operates 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
The switched port at Magnum DS60 units have address table capacity of 8K node
addresses, and 1MB dynamically allocated packet buffers, suitable for use in small and medium
size networks. They are self-learning, so that as nodes are added or removed or moved from
one segment to another, the DS60’s switched port 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.

4.5 (FF-A) Manual Switch, Port 6 for DS60C
The FF-A slide switch
allows users to configure Port 6 as either a
Full fixed at 10/100 port or act as an Auto-
negotiation Ethernet port. It is located
underneath Port 6 on the right front panel of
the Magnum DS60C. See figure 2.2.3 for
location of the switch relative to Port 6.
