the operating ambient temperature of the rack environment may be greater than 
room ambient. Therefore, consideration should be given to installing the equipment 
in an environment compatible with the maximum ambient temperature (Tma) 
specified by the manufacturer.  
B) Reduced Air Flow - Installation of the equipment in a rack should be such that 
the amount of air flow required for safe operation of the equipment is not 
compromised.  
C) Mechanical Loading - Mounting of the equipment in the rack should be such 
that a hazardous condition is not achieved due to uneven mechanical loading.  
D) Circuit Overloading - Consideration should be given to the connection of the 
equipment to the supply circuit and the effect that overloading of the circuits might 
have on overcurrent protection and supply wiring. Appropriate consideration of 
equipment nameplate ratings should be used when addressing this concern.  
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be 
maintained. Particular attention should be given to supply connections other than 
direct connections to the branch circuit (e.g. use of power strips)."

Connecting Ethernet Media 
The Magnum DS8016 Dual-Speed Stackable Hubs can be connected to the 
following two media types: 100BASE-TX and 10BASE-T.  CAT 5 cables should be used 
when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 
3  may be used.  In either case, the maximum distance for unshielded twisted pair cabling is 
100 meters (328 ft). 
Media 
               
IEEE Standard          Connector  
Twisted Pair (CAT 3, 4, 5)                  10BASE-T                  RJ-45 
          
Twisted Pair (CAT 5)  
 100BASE-TX                RJ-45            
 
NOTE :   It is recommended that high quality CAT. 5 cables (which work for both 10Mb 
and 100Mb) be used whenever possible in order to provide flexibility in a mixed-
speed network, since dual-speed ports are auto-sensing for either 10 and 100Mb/s.
