Preparing for the replacement
To prepare for the replacement:
1. Put on an ESD-preventive wrist strap, and make sure the wrist strap makes good skin contact and
is well grounded.
2. Unpack the card to be installed. If the card has a protection cover, remove it first.

NOTE:
Keep the removed blank panel and protection cover properly for future use.
Replacement procedure
To replace a card:
1. Loosen the captive screws on both sides of the card to be removed.
2. Pull the ejector levers outwards to separate the card from the backplane of the chassis.
3. Slowly pull out the card along the slide rails. Put the removed card on an antistatic mat or into its
original shipping materials.
4. Pivot the ejector levers outwards. Supporting the card with both hands, gently insert the card into
the slot along the slide rails.
5. Push the ejector levers inward to ensure close contact between the card and the backplane.
6. Position the screws into the holes and fasten them with a screwdriver to fix the card.
