Preparing for Installation
• Place a removed component board side up on an antistatic surface or in a static-shielding container. If
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components
• Never attempt to remove the printed circuit board from the metal carrier.
Note
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should
be between 1 and 10 Mohm.

Site Planning

The following sections describe how to plan for the installation of the Cisco ASR 903 Router:
