units operating in one managed stack.   Factory default switch settings cannot be relied 
upon, and the user must check and/or change the Group # address switch settings for 
each managed Magnum 3000 unit installed.  

 

If a network management software package is in use, the Group # addresses set 

for each Magnum 3000 physical unit will be reflected in the NMS displays, statistics and 

controls that correspond to that unit's Group # address.  (While non-sequential Group # 

addresses will not prevent the units in a stack from working properly in the network, such 

numbering tends to create problems for network administration and are therefore 

discouraged accordingly.) 

 

A Magnum 3000 stack may have from 2 to 20 active units (not including an 

optional 3000-AGT unit, which could be the 21st box in a large stack).  The stacked units 

may be any combination of Magnum 3024s, 3012s,3000X and they may be arranged in 

any order, physically and logically, for Group numbering purposes.  Switch settings for 

Group # addresses of zero and from 21 to 31 are not recognized by the NMS software in 

a managed system, and the use of such Group # addresses is discouraged. 

 

Switch 7 of the eight-position DIP switch is no longer used.  In previous 

versions of the product line it allowed the use of a PC-based SNMP AGENT.  Switch 8 

of the eight-position DIP switch is also unused. 

 

The "P1" DB-9 connector on the upper part of the rear panel is used for a serial 

port into the optional embedded SNMP agent board.  If there is no embedded agent board 

in a unit, "P1" is not present.  See Section 5.1 for operational information on the optional 

SNMP embedded agent board. 

The Magnum 3012 Hub provides 12 shielded RJ-45 ports on the front of the 

unit, and is otherwise like the Model 3024 described above.  Refer to the descriptive 

material in Section 2.3 above.
