Magnum DS50 / DS60s Dual Speed Hubs                  Installation and User Guide (06/02)

 

 

The Magnum  Dual-speed Hub Plus is designed to provide dual speed (10/100Mbps) 

connectivity.   Pictured below, a Magnum DS50 Dual-speed Hubs serves a small office with 

mixed speed requirements. Some 

users operate at 100Mbps, and some 

users and utility devices (such as 

print servers) run at 10Mbps.  All 

share the same hub, and 

communicate to each other via the 

bridge logic inside.  Any node can change speed at any time without affecting network 

operation or impacting other users.  It is simple to install and use, making shared Fast Ethernet 

networks practical for connecting high performance user groups in a variety of ways. 

 

Since 10/100 NICs are widely available at low cost, 100BASE-TX Fast Ethernet has 

become desirable for many performance-oriented users. They usually want their new 100Mb 

network segment to be interoperable with existing 10Mb networks, and to be a separate 

collision domain in order to maximize performance of both segments. This is where bridged-

dual-speed provides flexibility by enabling the newly installed 100Mb ports to communicate 

smoothly with existing 10Mb nodes and hubs.  

 

For this example, DS60C Port 6 may be used as a 10Mb port to an existing 10Mb hub 

while Ports 1-5 are a new separate collision domain of shared 10/100 ports.
