Installing and Launching the DCNM Client
The DCNM client is a web based application that you install on systems running Microsoft Windows XP Professional. When you finish installing the client on your system, the client automatically starts. After installing the DCNM client, whenever you need to restart the client, use the client software image on your system for the quickest start. If a more recent version of the client is available, the client automatically downloads that version to your system.
For more information about client system requirements, see the Cisco DCNM Release Notes, Release 4.0 at the following website: http://www.cisco.com/en/US/docs/switches/datacenter/sw/4_0/dcnm/release/notes
This chapter explains how to install and start the DCNM Client in the following sections:
•Prerequisites for Installing and Using the DCNM Client
•Downloading and Launching the DCNM Client
•Restarting the DCNM Client
•Reinstalling the DCNM Client
Prerequisites for Installing and Using the DCNM Client
Your system must be running Microsoft Windows XP Professional operating system to install and use the DCNM client software.
Note The installation process uses Java version 1.5. If your system does not have that version of Java, the installation process will download it to your system.
Before you can use the DCNM client, you must install the DCNM server and have it running. Some DCNM features are always available but the following features require that you install the DCNM Enterprise LAN license (see Installing Licenses, page 2-11):
•GLBP, Object Tracking, and Key Chains
•Dynamic ARP Inspection
•IP Source Guard
•Traffic Storm Control
•Traffic Management - Historical
For more information, see the Cisco DCNM Licensing Guide, Release 4.0.
Downloading and Launching the DCNM Client
When you install the DCNM Client, it automatically saves an image of the software on your Windows system and starts the client. Later on, when you start the client, you can quickly start it by using the image on your Windows system.
To download and start the DCNM client, follow these steps:
Step 1 Open a web browser on your Windows system and go to the following address:
For example, if the server IP address is 126.96.36.199, use the following address:
A window displays the introductory screen as shown in Figure 3-1.
Figure 3-1 DCNM Client Installer Screen
Step 2 Click "Launch DCNM Client."
The DCNM client installer verifies that Java is already installed on your system. If the installer does not find Java already installed, the installer performs one of the following actions:
•If you are using the Microsoft Internet Explorer browser, the installer automatically downloads Java version 1.5 or 1.6 onto your system and continues with the installation.
•If you are using another browser, such as FireFox Mozilla, the installer directs the browser to go to the Sun web site, and then you must download and install Java version 1.5 before restarting this procedure.
If the installer finds Java version 1.5 or 1.6 on your system (or downloads it there), the installer then downloads the client software and opens a window to prompt you about creating desktop and start menu shortcuts to the application, as shown in Figure 3-2.

Step 3 Click Yes.
The installer opens a window to prompt you for the DCNM server IP address, your user name, and your password as shown in Figure 3-3.
Note You might need to wait a minute or longer while the installer installs the software.

Step 4 Specify the DCNM server IP address, username, and password by doing the following:
a. In the DCNM Server field, type either the host name or the IP address for the DCNM server system.
b. In the Username field, type "admin".
c. In the Password field, type "admin".
Note When you first install the DCNM client, the username and password values are the default settings that you use when you first install the client. After you install the software, you should create secure usernames and passwords, as explained in Administering DCNM Server Users, page 9-24.
d. Click OK.
Step 5 The DCNM Client opens as shown in Figure 3-4.

You are ready to discover the devices that DCNM will manage. To discover devices, see Administering Device Discovery, page 9-1.
For information on how to use the DCNM client, see Chapter 4, "Using the DCNM Client."
Restarting the DCNM Client
After you have installed the DCNM client software, you can start the DCNM client by using the desktop shortcut or the start menu command for the DCNM client. When you start the client, the client automatically checks to see if there is a new version of the software on the web. If the version already downloaded is newest, then that version is used and the DCNM client window opens quickly. If a newer version exists on the web, the client downloads the newer version and runs that.
To restart the DCNM client, follow these steps:
Step 1 Click the desktop icon for the software (see Figure 3-5) or choose Start > Programs > DCNM 4.0 Client > DCNM 4.0 Client.

The client opens a window to ask for your username and password, as shown in Figure 3-6. By default, this window lists the IP address for the previously discovered device. You can use the host name for the DCNM server in place of the IP address.

Step 2 Type your username and password, and then click Login.
Note If you need to change the IP address used for the server, you can also specify the IP address.
Note If you have not already created a unique username and password, you should do that to secure the access to DCNM. To create a new username or to change your password, see Administering DCNM Server Users, page 9-24.
The DCNM client opens as shown in Figure 3-7.
