When the MPC along with the ADC is out of the chassis, do not hold it by
the ejector handles, bus bars, or edge connectors. They cannot support
its weight.
Do not stack MPCs with the ADCs 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.
To remove an MPC without an ADC (see
