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:
Performing Self Diagnostics . . . (pause for 30 to 60 seconds typically)

Ethernet address 00 00 1A 18 0E 18 IP address 45.9.0.5 (example)
5.4.1 Automatic Agent IP Address Configuration.
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.
5.4.2 Manual IP Address Configuration.
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.
