Aruba Airwave - Configuring Origin when adding Floorplan to VisualRF

Airwave is the network management platform from Aruba for managing their (and other vendors) wired and wireless equipment. One key part are the live floor plans accessed via the VisualRF menu. These show when APs are up or down, the clients connected to them and can also show heat maps and AP relationships.
When adding floor plans and setting up buildings in Aruba Airwave, there are several important factors to ensure are correct. One is that the scale of the plan is correctly set and the second is the location of the origin. The origin controls the alignment of floors so that VisualRF knows where floors above and below are located relative to one another. Without this the client location will not be correct and the heat maps inaccurate.

In these screen captures the origin is in the default location at the top left of the imported floor plans of the ground and first floors. However the amount of white space around each plan is different.

By enabling the heat map showing the signal from APs on the floor above the misalignment between floors is clear as the APs are offset to the left of their real locations.

To correct this unlock the floor plan by clicking on the padlock and then drag the origin marker to a point that is common to both floors, an elevator is ideal but a common corner of a building can also be used. Now looking at the same heat map the signal from the APs above are correctly located.
