• OSN3: Connect an RJ-45 network cable to the RJ-45 serial port of the OSN3
module ( ), and then connect the other end of the cable to the serial port of
your PC.
Figure 10-4: Cabling OSN3 to PC for Serial Communication
Notes:
• The OSN3 does not provide a direct monitor connection (Micro HDMI port), and
therefore, the serial port is used for determining the Ethernet port NIC.
• If you are running the OSN3B/OSN4 and wish to perform this procedure using the
HDMI interface instead of the serial interface, see Section 30.2 on page 220.
• For the Mediant 1000B OSN3B/OSN4 serial interface port (micro-USB) to be
operational, you must download a special USB driver from the Internet. Download this
driver at

4. Establish a serial communication with the OSN server, using a terminal emulation
program, such as HyperTerminal, with the following port settings:
• Bits per second: 115200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
5. Press Enter; the Serial Console prompt is displayed:
SAC>
6. Type the following to view all the NIC addresses:
SAC>i
7. Do one of the following:
• If you have a DHCP server in your network, the internal NIC should be identified
by a displayed IP address (the two external Ethernet ports should be displayed as
"Disconnected").
• If you are not using a DHCP server, assign a static IP address to the NIC of the
internal Ethernet port using the following command and then press Enter to apply
your settings:
SAC>i <NIC ID> <IP address> <subnet> <default gateway>
8. Disconnect the serial cable from the OSN server.
