To remove an MPC with an adapter card (ADC):
Have ready an antistatic mat for the MPC with an ADC. Also have ready rubber safety

caps for each MPC using an optical interface on the MPC that you are removing.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to an approved site ESD grounding point. See the instructions for your site.
Open both the ejector handles simultaneously to unseat the both the MPC and the

ADC.
Grasp the handles, and slide the MPC along with the ADC straight out of the card cage

halfway.
Place one hand around the front of the MPC with the ADC and the other hand under

MPC to support it. Slide the MPC along with the ADC completely out of the chassis,
and place it on the antistatic mat or in the electrostatic bag.
CAUTION: The weight of the MPC with the ADC is concentrated in the
back end. Be prepared to accept the full weight—up to
25.0 lb (11.34 kg)—as you slide the MPC along with the ADC out of the
chassis.
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.
