Juniper Networks M160 manual Installing an MCS, Removing an MCS

Replacing Hardware Components

6.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

NOTE: Wait until a message appears on the console confirming that the operating system has halted.

For more information about the command, see the JUNOS Protocols, Class of

Service, and System Basics Command Reference.

7.Push the end of each extractor clip (located at each end of the MCS) outward.

8.Grasp the extractor clips and slide the MCS about halfway out of the chassis.

9.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.
