Steps
To install the inlet grille, perform the following steps:
Step 1 Remove the new inlet grille from its packaging, then set the packaging aside.
Step 2 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 3 Align and insert the hooks at the bottom of the inlet grille into the cutouts at the bottom of the chassis
casing on the front (PLIM) side of the chassis, just in front of the power modules.
Step 4 Rotate the top of the inlet grille toward the chassis, and snap it into place on the ball studs.
What to Do Next
After performing this task, you may power on the chassis. See Chapter 2, “Installing and Removing
Power Components.”
Removing the Inlet Grille—Fixed and Modular Configuration Power Supply
This section describes how to remove the inlet grille from a Cisco CRS 8-slot line card chassis. The

installed. The grille covers the power module and air intake areas at the bottom of the front (PLIM) side
of the chassis, just below the card cage.
