Magnum DS50 / DS60s Dual Speed Hubs 4.2 Installation and User Guide (06/02) Auto-negotiation and speed-sensing The first five RJ-45 ports independently support auto-negotiation for shared 10BASE-T and 100BASE-TX modes. Operation is according to the IEEE 802.3u standard. When an RJ-45 cable connection is made and each time a LINK is enabled, auto-negotiation takes place.
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 multicast 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.
Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02) After switching from Full fixed to auto-negotiation or vice versa, it is necessary that the unit be powered down and back up to reset the internal buffers of the switch. Even though it is not always required, powering down and up will enable proper packet handling in all cases for both segments of the network. 4.
