CAUTION: The weight of line cards in EX9200 switches is in the range 14–19.4 lb
(6.6–8.8 kg). Be prepared to support the full weight as you slide the line card into the
chassis.
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 removing a line card, wait for at least 30 seconds before installing a
line card or removing another line card.
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.
Figure 78 on page 253 shows removing a line card from an EX9204 switch. The procedure and
orientation of the line card are the same for EX9208. The procedure is the same for EX9214 switch;
however, the orientation of the line cards is different—it is installed vertically into the top and bottom of
the chassis.
