ejector handles might bend them. Bent ejector handles prevent line cards from being
properly seated in the chassis.
CAUTION: Do not stack line cards on top of one another or on top of any other
component. Place each line card separately in the antistatic bag or on the antistatic
mat placed on a flat, stable surface.
6. Grasp the handles and gently slide the line card halfway out of the chassis (see
Line Cards
).
7. Place one hand around the faceplate of the line card and the other hand under the line card to
support it. Taking care not to touch line card components, pins, leads, or solder connections, gently
slide the line card completely out of the chassis and place it in an antistatic bag or on its own
antistatic mat placed on a flat, stable surface.
CAUTION: After the OK/FAIL LED is unlit, wait at least 30 seconds before inserting
the line card, removing a line card from a different slot, or inserting a line card in
another slot.
8. If you are not installing a line card in the emptied line card slot within a short time, install a cover
panel over the slot. Do this to protect the interior of the chassis from dust or other foreign
substances and to ensure that the airflow inside the chassis is not disrupted.
