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.
