Overview of Preparing the Site for the MX2020 Router

To prepare a site for router installation:

1. Verify that environmental factors such as temperature and humidity do not exceed router tolerances. See:

   • MX2020 Router Environmental Specifications

2. Verify that the site and installation plan meets all safety guidelines and requirements. See:

   • General Electrical Safety Guidelines and Warnings

3. Locate sites for connection of system grounding. See:

   • MX2000 Router Grounding Specifications

4. Calculate the power consumption and requirements.

   Measure distance between external power sources and the router installation site. See:
