How an 
Unconfigured 
Module Obtains 
an IP Address
On startup, an unconfigured NOE 771 xx module ("as shipped") will attempt to 
obtain an IP address by issuing BOOTP requests. When a response from a BOOTP 
server is obtained, the IP address in the response is used. If no BOOTP response 
is received within two minutes, the module uses the default IP address derived from 
its MAC address.
Note: The MAC address is assigned at the factory and is recorded on a label on 
the front panel, above the cable connector. This is a unique 48-bit global assigned 
address. It is set in PROM. The Ethernet address is recorded on the label in 
hexadecimal, in the form 00.00.54.xx.xx.xx.
