Chapter 5 Installing and Removing Exterior Components

Installing or Removing the Front Side Exterior Components

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 procedure is the same for a chassis with a fixed configuration and a modular configuration power supply 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.

Prerequisites

No prerequisites exist for this task.

Steps

To remove the inlet grille, perform the following steps:

Step 1 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 2 While facing the front (PLIM) side of the chassis, firmly grasp the top outside edges of the inlet grille. Step 3 Pull the top of the grille firmly away from the chassis; it loosens from the connecting ball studs.

Step 4 Slide the hooks at the bottom of the grille free of the cutouts at the bottom of the chassis casing. Step 5 Carefully set the inlet grille aside.
