Figure 81: Removing an MCS

Installing an MCS

To install an MCS, follow this procedure (see Figure 82):
1.
On the console or other management device connected to the Routing Engine
that is paired with the CB you are removing, enter CLI operational mode and
issue the following command. The command shuts down the Routing Engine
cleanly, so its state information is preserved:
user@host> request system halt
For more information about the command, see the JUNOS Protocols, Class of
Service, and System Basics Command Reference.
Push the end of each extractor clip (located at each end of the MCS) outward.
Grasp the extractor clips and slide the MCS about halfway out of the chassis.
Place one hand under the MCS to support it, slide it completely out of the
chassis, and place it on the antistatic mat or in the electrostatic bag.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
"Preventing Electrostatic Discharge Damage" on page 226.
