Removing the CB-REs Before Installing the MX2020 Router

Copyright © 2015, Juniper Networks, Inc.
CAUTION: The weight of the MPC is concentrated in the back end. Be
prepared to accept the full weight—up to 18.35 lb (8.32 kg)—as you slide
the MPC out of the ADC.
When the MPC is out of the ADC, do not hold it by the knobs, bus bars, or
edge connectors. They cannot support its weight.
Do not stack MPCs 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.
