Another DS8016 model, the DS8016-A, has no switch module inside, but is dual 

speed and is normally used stacked with a DS8016-B for dual-speed port expansion.

Only one DS8016-B unit is needed to support a stack.  Additional 16-port units of 

the DS8016-A “add-on” and/or DS8016-E “100-only” hubs . . . units that do not have the 

bridge module inside, and which cost less accordingly . . . can be added to the stack, up to the 

3-unit stack maximum. In a stack, the DS8016-B unit (illustrated below as the bottom unit) 

can be in any stack position.

DS8016-A units can also be used without a DS8016-B, whereupon they will 

function as dual-speed stackable hubs. This could be desired if an external non-auto-sensing 

switch (such as the Magnum 300ES Two-Port Switch) is available to interconnect the two 

speed domains, or if only 100Mb devices are connected (use the DS8016-E for this? See 

2.2.3 below) and the 10Mb domain is unused, or if dual-speed operation with two 

unconnected and uncoordinated domains is needed for the application. 

        Each DS8016 has its own internal power supply, and is easily added to an existing 10 or 

100Mb network.  DS8016s are suitable for wiring closet shelf, table-top or 19” rack-

mounting.  Optional brackets for 23” telco rack-mounting are available. 

  The Magnum DS8016 chassis houses one main PC board, a bridge module daughter- board 

in the Model DS8016-B and DS8016-R, and an internal power supply unit.  The front side of 

the chassis has sixteen RJ-45 twisted-pair ports, one of which (Port #1X on the left-front) can 

be used for cascading (UP-LINK).
