NOTE: Because a line card is heavy, and because antistatic bags are fragile, inserting the line card
into the bag is best done with two people, each to do one of the following steps.
To insert a line card into an antistatic bag:
1. Hold the line card in the horizontal position with the faceplate facing you.
2. Slide the opening of the bag over the line card connector edge.
If you must insert the line card into a bag by yourself:
1. Lay the line card horizontally on a flat, stable surface, sheet metal side down.
2. Orient the line card with the faceplate facing you.
3. Carefully insert the line card connector edge into the opening of the bag and pull the bag toward you
to cover the line card.
Maintaining Line Card Cables
Components in the line cards are fragile. To extend the lives of your line card cables and to avoid
problems that can result from cable damage, follow these procedures:
To maintain line card cables:
• Place excess cable out of the way. Do not allow fastened loops of cable to dangle from the
connector. Placing fasteners on the loops helps retain their shape.
• Keep the cable connections clean and free of dust and other particles, which can cause drops in the
received power level. Always inspect cables and clean them if necessary before connecting a port.
• Label both ends of line card cables to identify them.
Removing a Line Card from an EX9253 Switch
Before you begin to remove a line card from an EX9253 switch:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage. See
