One of three different methods are used to set up NetMRI Collector nodes in an Operations Center deployment:

- You can install a new NetMRI instance on a VM (or a NetMRI physical appliance, for that matter), allow it to fully discover the network, and then run the **register **command to register the NetMRI instance with a newly configured Operations Center;
- You can install the Operations Center and run the Setup Wizard to perform initial Then, install the NetMRI virtual appliances, that will act as Collectors, into their VMware servers. On each NetMRI VM, run the NetMRI admin shell **configure server **command to set up basic IP information and immediately run the NetMRI admin shell **register **command to register the NetMRI VMs to the Operations Center. Global settings will be synchronized with the OC node and you configure the discovery ranges and other Discovery settings in the OC for the network-wide process. This procedure is described in this section;
- Migrate from a standalone NetMRI appliance to an Operations Center environment. For more information, see *[Configuring An Operations Center Controller From an Existing NetMRI Instanc](https://infoblox-docs.atlassian.net/wiki/spaces/OCDeployGuide/pages/142902261/Installing+the+Operations+Center+Software#InstallingtheOperationsCenterSoftware-ConfiguringAnOperationsCenterControllerFromanExistingNetMRIInstance)*[e](https://infoblox-docs.atlassian.net/wiki/spaces/OCDeployGuide/pages/142902261/Installing+the+Operations+Center+Software#InstallingtheOperationsCenterSoftware-ConfiguringAnOperationsCenterControllerFromanExistingNetMRIInstance).

After installing the Virtual appliance in your VMware server, follow the instructions below.

To configure it to run on your network.

1. Log in to VMware Virtual Center, ESX, Workstation, etc.
2. Power on the NetMRI Virtual appliance you imported earlier.
3. Open the console view of the NetMRI virtual appliance.
4. After the initial boot, you will see a license. Read the agreement (press **Space** to page down). At the prompt, enter **yes** and then press **Enter**.
5. The boot will continue for about five minutes as the NetMRI application configures itself.
6. When the blue screen is displayed, select **Log in **using the arrow keys, then press **Enter**.
7. Enter the default user name **admin **and the default password **admin**. This puts you in the admin shell of NetMRI, a command-line interface.
8. Run the `configure server `command and define the IP configuration for the NetMRI virtual machine.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ You can change the password later when running through NetMRI’s browser-based interface.

Repeat the instructions in this section for each NetMRI instance you want to add to the Operations Center system.

1. Log in to the admin shell on the NetMRI instance being added to the Operations Center system.
2. At the command prompt, run the `register` command.
3. At the `Register this system?` prompt, respond with **y**.
4. The instance will automatically restart. After restarting, the instance will be a Collector in the Operations Center system.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ As part of the registration process, the admin password on the Collector is synchronized with the password on the Operations Center Controller. Therefore, after registration is complete, the admin password for the Collector may be different than the password you initially used to log in to the admin shell on that instance.

After registration, the NetMRI GUI is not visible on this instance. All access to the instance must be through the Controller. You access the NetMRI GUI from the Operations Center Controller.

When you execute Discovery on the Operations Center, it automatically uses the outlying Collectors as its means for performing Discovery on the network.
