# Working with the Navigation Tree

Expanding Collapsing Tree Nodes

#### The Navigation Tree super-nodes can be expanded or collapsed at any time in order to quickly view or hide sub nodes or hardware contained in the Navigation Tree.

1. In order to expand or collapse the entire Navigation Tree and all displayed super-nodes select Tree -> Collapse All or Tree -> Expand All for the desired result.

Hide/Show Navigation Tree

The entire Navigation Tree panel can be displayed or hidden from view when it is not required.

1. In order to toggle the Navigation Tree between display and hide modes, select Tree -> Hide/Show Tree from the main menu. Hiding the Navigation Tree allows the user to dedicate more display area for alarm views, configuration views, graphics views or monitoring client grids.

The toolbar button labeled "Hide/Show Tree" can also be used to toggle the Navigation Tree on and off.

Manually Adding Hardware

Depending on network conditions or if the Discovery Subsystem is disabled, the Automatic Discovery System may not find your frame or products. In this case you can select to manually force discovery on a frame that is known to be connected to the network. Performing an Add/Update Frame on a device which is already present in the Hardware view will cause the discovery system to rediscover and verify the device and all contained modules.

To Force a Frame Discovery:

1. Select Tree -> Add/Update Frame . The Add/Update Frame dialog box will appear.

2. Enter the IP address of the frame that you want to manually add, and then select the "OK" button. If the frame is already in the Hardware View you can select the IP address from the drop-down list presented.
3. The Discovery Subsystem will now attempt to directly contact the specified frame.

- If the frame cannot be contacted it will not be added to the Navigation Tree's Hardware super-node.

- If contact is established then the Discovery Subsystem will detect all products in the frame and the frame will be added to the Navigation Tree's Hardware super-node.

Refresh Network View

The Navigation Tree discovered hardware can be refreshed at any time by selecting Tree -> Refresh from the main menu. Selecting this option will initiate an Auto Discovery cycle disregarding the Discovery Interval setting.

All present frames will be updated with any newly added or removed modules. All newly added or previously undiscovered hardware will be added to the Navigation Tree's Hardware super-node.

The toolbar button labeled "Refresh Network View" can also be used to perform this action.

Cleanup Network View

If products have been removed from a frame or a frame has been disconnected from your network the Navigation Tree will show the frame and/or products, however, they will appear disabled. If you know that the hardware does not exist on the network or has been permanently removed you can force VistaLINK™ PRO to "clean up" the Navigation Tree by removing the disabled hardware. To do this, select Tree -> Cleanup from the main menu.
