Chapter 3 Installing the AVS 3120
Establishing a Serial Console Connection
Establishing a Serial Console Connection
Before you can configure the AVS 3120 by using the command line interface (CLI), you must establish
a serial console connection to it. This requires a PC, a DB-9 to RJ-45 adapter (provided), an RJ-45
180/rollover cable (provided), and terminal emulation communication software (Hyper Terminal or
equivalent). You may also use a serial concentrator connection, if desired.
To establish a serial console connection, follow these steps:
1. Connect a console to the serial console port on the rear panel:
a. Attach a DB-9 or DB-25 to RJ-45 adapter to the serial port of the console computer.
b. Use the RJ-45 180/rollover cable to connect the console to the console serial port on the AVS
2. If you have not already done so, power up the AVS 3120 as described in the “Booting the AVS 3120”
3. Open your terminal emulation application on your PC to access the AVS 3120 CLI. The following
procedure uses HyperTerminal for Windows:
a. Launch HyperTerminal. The Connection Description window appears.
b. Enter a name for your session in the Name field.
c. Click OK. The Connect To window appears.
d. From the drop-down list, choose the COM port to which the device is connected.
e. Click OK. The Port Properties window appears.
f. Set the port properties:
Baud Rate = 9600
Data Bits = 8
Flow Control = none
Parity = none
Stop Bits = 1
g. Click OK to connect.
h. Press Enter to display the CLI prompt.
4. After you create a session, choose Save As from the File menu to save the connection description.
Saving the connection description has the following two advantages:
–
The next time you launch HyperTerminal, the session is listed as an option under
Start > Programs > Accessories > HyperTerminal > Name_of_session. This option lets you
reach the CLI prompt directly without repeating the configuration steps.
–
You can connect your cable to a different device without configuring a new HyperTerminal
session. If you use this option, ensure that you connect to the same port on the new device as
was configured in the saved HyperTerminal session. Otherwise, a blank screen appears without
a prompt.
For information about using the CLI to configure the AVS 3120, refer to the following section,

Step 5
Configure the local time zone with the set date tz command:
velocity>set date tz timezone
where:
timezone is the local city/time zone name, such as America/New_York. To see a list of available
city/time zone names, use the command show timezone all. The default time zone is America/Tijuana.
You can view the current time zone setting by using the show timezone current command:
velocity>show timezone current
America/Tijuana
Step 6
Configure the initial date and time setting. You can do this automatically by synchronizing to a network
time protocol (NTP) server, or manually by using the set date time command. To use an NTP server, use
the set ntp command, as follows:
velocity>set ntp start ip
where:
start can be start, to start using NTP, or stop, to stop using NTP
ip is the NTP server IP address or fully qualified domain name, such as 10.68.226.100 or time.nst.gov
You can view the NTP settings by using the show ntp command:
velocity>show ntp
STATUS: RUNNING
NTP SERVER: time.nist.gov
If you would rather manually set the time, use the following command:
velocity>set date time MM:DD:hh:mm:YYYY
where MM:DD:hh:mm:YYYY is month:day:hour:minute:year
You can view the time and date by using the show date command:
velocity>show date

Setting the Time
Step 8
We also recommend that you change the account password from its default. To do this, use the
edit admin command:
velocity>edit admin current-name fgn new-password password
where:
password is the new password for the fgnaccount.
For more details about using the CLI and the Management Console, refer to the Cisco Application
Velocity System User Guide.
Setting the Time
Many features of AVS depend on having the clocks synchronized among all of the deployed AVS devices
and the origin servers. It is important to synchronize all clocks whenever a new device is deployed.
Here is a summary of the ways to set the clock on an AVS device:
•
•
Use the set date command to set the date, time, and local time zone.
Use the set ntp command to configure the AVS device to get its time from an NTP time
synchronization source. The NTP source should be the same for all deployed AVS devices and origin
servers.
Note
We recommend that you use an NTP time synchronization source.
For information on using the CLI to configure the AVS 3120, refer to the Cisco Application Velocity
System User Guide. For an example of using the set ntp and set date commands, refer to the previous
