To ensure protection against debris getting through the lower grille and into the chassis bay, Cisco Systems
provides a screen that you can install behind the lower grille.
This section describes how to install the inlet grille screen in the LCC.
To install the inlet grille screen kit (CRS-16-SCREEN-KIT) as an update to an existing system, you must:
1. Remove the lower grille from the front (PLIM) side of the chassis.
2. Remove the lower grille frame assembly that is currently installed.
3. Install the new lower grille screen and frame assembly.
4. Re-install the original lower grille on the front (PLIM) side of the chassis.

Required Tools and Equipment

You need the following tools and parts to perform this task:
• 8 in. long number 1 Phillips screwdriver—magnetic head preferable
• Lower grille screen and frame assembly
