# Overview

Now that you have installed the cells the next step is to update the cell data in the i2b2 Administration Module. The following steps will guide you through the process of editing existing cell data. This is needed for any installation that does not use the demo URLs (i.e. http://localhost:9090/...)

Important

In the *Data Installation* chapter, the cell data for the required i2b2 core cells was loaded into the cell data table when installing the Pmdata.

By default the cells are configured to work with the i2b2 demo database. This means *localhost* and port *9090* are part of the cell's address.

- You will need to edit the cells data if you changed any of default settings.
- You can skip this step if you did not change the default settings.

To be safe you may want to review the default settings at least once to determine if anything is different in your environment.

# Edit Existing Cell Data

1. Log into the i2b2 Administration Module.

**http://*localhost*/admin**

2. Click on **Manage Cells** located in the navigation panel on the left.
