extensions data are in this firmware. The firmware in the EPROMs performs the data collection and execution functions, and operates as the local controller and interface to the network manager.

5.1.2Separate Agent Box, Model 3000-AGT

The Magnum 3000 SNMP Agent Box operates the same as the embedded

board agent. It is packaged as a separate unit, enclosed in a box that is the same dimensions as a 3024 or 3012 so that it fits neatly into a Magnum 3000 stack. It is a complete modular unit with its own internal auto-ranging power supply.

The Magnum 3000-AGT agent box is connected into a stack by the Inter- Repeater Bus (IRB). There are two IRB connectors at the right-rear, permitting the agent box unit to be installed at the bottom or top of a stack using one IRB connector, or to be inserted into the middle of a stack using two IRB connectors. The IRB cable connectors are made with "notches / keys" to insure a proper connection.

The agent logically resides on the IRB and will not be visible to network management software packages as a separate port or user. For network integrity, the agent is designed so that it cannot be disconnected by network managers accidentally or purposefully. Similarly, the agent operates in the stack attached to the IRB and does not need to use a port in any attached Magnum 3000 unit to be connected.
