NOTE:
Remove the cables on a card before removing the card.
To replace a card:
1. Prepare an antistatic mat to place the removed card.
2. Wear an ESD wrist strap and make sure it has a good skin contact and is correctly grounded. For
more information, see "Installing FRUs."
3. Use a Phillips screwdriver to remove the captive screw on the card, as shown by callout 1 in Figure
50 .
4. Move the ejector levers outwards to separate the card from the backplane, as shown by callout 2
in
Figure 50 .
5. Use one hand to slowly move the card outwards. Supporting the bottom of the card with the other
hand, pull the card out of the slot along slide rails, as shown by callout 3 in
Figure 50 .
6. Put the removed card on the antistatic mat.
7. Install a new card. For the installation procedures, see "Installing FRUs."
If no new card is to be installed, install a blank panel to ensure heat dissipation of the switch and
prevent dust from entering the switch.
