Figure 5-2 Remove a card
Follow these steps to remove a card:
1) Wear an ESD-preventive wrist strap and loosen the captive screws on the card
with a screwdriver (see callout in ①
Figure 5-2).
2) Hold the ejector levers on the card with both hands and press them outward to
separate the connectors of the card from the backplane (see callout in ②
Figure
5-2).
3) Pull part of the card out along the guide rails slowly, then hold the card bottom with
one hand (do not touch its circuit) and pull it out of the chassis with the other hand
(see callout in ③
Figure 5-2).
 Note:
If you are not going to install a new card after removing a card, install a blank panel on
the slot for the dust-proof purpose.
