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  
3120. For the location of the serial port, see Figure 3-4.  
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,  
“Configuring Network Settings” and the Cisco Application Velocity System User Guide.

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
