The host subsystem is taken offline and brought online as a
unit. Before you replace an SCB or a Routing Engine, you must take the host subsystem offline. The host subsystem is hot-pluggable,
but taking the host subsystem offline causes the device to
shut down.
To take a host subsystem offline:
On the console or other management device connected to
the Routing Engine that is paired with the SCB 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
Wait until a message appears on the console
confirming that the operating system has halted.
For more
information about the command, see the JUNOS System Basics and Services Command Reference.
Note:
The SCB might continue forwarding traffic for approximately
5 minutes after the request system halt command has been
issued.
