Chapter 3 Removing and Installing Line Cards
Warnings and Cautions
Warnings and Cautions
Observe the following warnings and cautions when installing or removing line cards.
Caution Do not slide a line card all the way into the slot until you have connected all required cables. Trying to
do so disrupts normal operation of the router or switch.
Note If a line card lever or other retaining mechanism does not move to the locked position, the line card is
not completely seated in the backplane. Carefully pull the line card halfway out of the slot, reinsert it,
and move the line card levers to the locked position.
Caution To prevent jamming the carrier between the upper and the lower edges of the line card slot, and to ensure
that the edge connector at the rear of the line card mates with the connection at the rear of the line card
slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following
illustrations.
Warning
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the
midplane or backplane with your hand or any metal tool, or you could shock yourself.
