Use the following procedure to use an Ethernet connection:
1. Telnet to the UltraNet Edge 3000 via the Ethernet maintenance
interface.
Once you are connected to the UltraNet Edge 3000, the tm.0x10>

connection is not made immediately, the auto-boot sequence will
start and you will no longer be in the prom mode.
If the auto-boot sequence is not interrupted, you will see the
