# Overview

Although this step of the installation is optional it is highly recommended that you do a "Sanity Check" to make sure the IM Cell was installed correctly before installing another cell.

# Verify Web Services

At this point in the installation process you want to do a quick check to make sure the Web Service for the IM Cell is running.

### Steps to verify web services
