To check the status of a specific SCB, issue the show chassis environment cb node slot command, for
example, show chassis environment cb node 0.
For more information about using the CLI, see the CLI Explorer .
Taking the SRX5800 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 www.juniper.net/documentation/ .
NOTE: The SCB might continue forwarding traffic for approximately 5 minutes after the
request system halt command has been issued.
Operating and Positioning the SRX5800 Services Gateway SCB Ejectors
•
When removing or inserting an SCB, ensure that the SCBs or blank panels in adjacent slots are fully
inserted to avoid hitting them with the ejector handles. The ejector handles require that all adjacent
components be completely inserted so the ejector handles do not hit them, which could result in damage.
•
The ejector handles have a center of rotation and need to be stored toward the center of the board.
Ensure the long ends of the ejectors located at both the top and the bottom of the board are vertical
