CAUTION: The weight of the MPC with the adapter card is concentrated in the
back end. Be prepared to accept the full weight—up to 25 lb (11.34 kg)—as you
slide the MPC along with the adapter card out of the chassis.
When the MPC along with the adapter card 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 adapter cards 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.
Removing the MPCs Without Removing an Adapter Card Before Installing an MX2010 Router
To remove an MPC only, without removing the adapter card (see Figure 94 on page 250 ):
1. Have ready an antistatic mat for the MPC. Also, have ready rubber safety caps when removing MPCs
that have optical interfaces.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instructions for your site.
3. Simultaneously turn both the knobs counterclockwise to unseat the MPC from the adapter card.
4. Grasp both knobs, and slide the MPC straight out of the adapter card.
5. Place one hand around the front of the MPC and the other hand under it to support it. Slide the MPC
completely out of the adapter card, and place it on the antistatic mat or in the electrostatic bag.
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 adapter card.
When the MPC is out of the adapter card, 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.
