Taking the SRX5400 Services Gateway Host Subsystem Offline
The host subsystem is composed of an SCB with a Routing Engine installed in it. You
take the host subsystem offline and bring it online as a unit. Before you replace an SCB
or a Routing Engine, you must take the host subsystem offline. Taking the host subsystem
offline causes the device to shut down.
To take the host subsystem offline:
1.
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
2.
Wait until a message appears on the console confirming that the operating system
has halted.
For more information about the command, see
Junos OS System Basics and Services
Command Reference
at
NOTE:
The SCB might continue forwarding traffic for approximately 5
minutes after the
request system halt
command has been issued.
