the strap to one of the ESD points on the chassis. For more information about ESD,
see "Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series

CAUTION: The weight of the FPC is concentrated in the back end. Be
prepared to accept the full weight—up to 15 lb (6.8 kg)—as you slide
the FPC out of the chassis.
When the FPC is out of the chassis, do not hold it by the ejector levers,
bus bars, or edge connectors. They cannot support its weight.
Do not stack FPCs on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a
flat, stable surface.
Repeat Step 4 for each FPC card carrier or blank cover, proceeding from left to right.
