operations:  CPU test,  EPROM CRC test,  DRAM test,  Network Interface Controller 

test and  NVRAM test. 

 

During the configuration process, an ANSI compatible terminal or a PC 

running ANSI terminal emulation software should be connected (through a null modem 

cable) to the serial port "P1" located on the rear panel of the Magnum 3000 unit.  The 

terminal characteristics should be set to: 9600 Baud, 8 bit data, no parity, 1 stop bit. 

 

If the agent board (either embedded in a unit, or in a box by itself) is operating 

properly, the following (example) message will appear on the terminal screen:

At power up, the agent software program will search for an IP address in 

NVRAM.  A legitimate IP address is set into the NVRAM at the factory, permitting the 

unit or stack when new to automatically go into operation as a stand-alone network.  

 

For more complex networks where the IP address is to be set from a server on 

an existing network, set the NVRAM IP address to a blank using the procedure in 

"Function Listing, Address" below.  Then, at power up when the agent software program 

does not find an IP address, it will try to get configuration information from a boot server 

by using the BOOTP protocol.  If this attempt fails, it will try RARP protocol.  This 

process may require up to one minute.  

 

Next, the agent automatically determines the configuration of the Magnum 

3000 stack by reading the group # addresses of all of the units in the stack.  The stacked 

units, from one to twenty in number which operate as one repeater, will have one 

repeater agent and its IP address.  (Note that a group # address should be set for each unit 

by using switches on the back of each unit.  See Section 4.3, Table 4.3.  

If  the network does not support BOOTP or RARP, or if you need to manually 

change the agent's IP address to a user-specified address, it can be done from a terminal 

(see 4.4 above) connected to the serial port P1 on the back of the Magnum 3000 unit 

containing the embedded agent, or to P1 on the agent box.
