plugs into the main board and into the power supply with other assorted cables.  The 

exact type and number of cables and connectors for this installation varies depending 

upon the vintage of the hub unit being upgraded.  Kits may sometimes be available from 

GCI's Spare Parts List with parts and instructions to suit the different unit revs.  Consult 

with GCI Tech Support for additional information.

If in doubt about the vintage of your 3012 upgrade candidate, use the "AGT" 

box model for the upgrade. 
 

Step 3.    Set Group # (Stack) Address - Magnum 3024/3012  

 

On the back of  Magnum 3000 Stackable hubs  is an eight position DIP switch.  

The first six positions are used to identify each unit in binary code as a Group # address.   

Switches 7 and 8 are not used.

For managed stacks, the unit configured with the embedded SNMP agent in it 

should be set to the # 1 Group address.  The "AGT" agent box unit, if used in a stack, has 

no Group # address itself.  See also Table 4.3 and Section 2.3.2, "Group # Address 

Switch Settings". 

 

 From the perspective of the network manager, the Magnum SNMP agent board 

or box is not visible as a separate user or port.  It cannot be disabled either accidentally or 

purposefully.  This prevents the agent itself from being disconnected, causing an 

irreversible loss of control of the entire stack from the network manager.
