4. Using a Phillips screwdriver, loosen the two installation screws on
the faceplate of the line card. See Figure 19.

5. Pull the line card forward and remove it from the chassis.
Once you have removed the line card from the chassis, the WAIT/
REMOVE LED turns amber. After approximately 20 seconds, the
WAIT/REMOVE LED turns steady green.
Caution
Be sure to observe all standard electrostatic discharge (ESD)
precautions, such as wearing an antistatic wrist strap, to avoid
damaging the device. Store the line card in an antistatic bag or
immediately install it in another slot. A line card can be damaged by
static electricity.
6. When the WAIT/REMOVE LED is steady green, you must install either
a blank faceplate or another line card into the empty slot.
The faceplate keeps dust from getting into the chassis and
maintains proper airflow.
To install a line card, see Installing a Line Card on page 25.
