Retrieving the IP Address of the Rear Ethernet Port (Host)
To retrieve the IP address of the rear Ethernet port:
1. If necessary, turn on your unit. If the unit was not powered on yet,
see Turning On or Off the Unit on page 48 for more information on the
startup sequence and waiting time.
Note: It may take a few minutes before your unit and the computer could “see”
each other.
2. Connect your portable computer to the front Ethernet port of the unit.

If you have already connected a network cable to your unit, simply
connect the free end of the cable to your computer.

Otherwise, connect a network cable between the unit (front port)
and your computer. You will have to wait about 60 seconds that the
detection of the port is complete once the operating system is
started.
3. Turn on your computer.
