Juniper SRX5400 - Taking the SRX5400 Services Gateway Host Subsystem Offline; Operating and Positioning the SRX5400 Services Gateway SCB Ejectors

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 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 SRX5400 Services Gateway SCB Ejectors
•
When removing or inserting the SCB, ensure that the cards 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 must be stored toward the center of the board. Ensure the long ends of the ejectors
located at both the right and left ends of the board are horizontal and pressed as far as possible toward
the center of the board.
•
To insert or remove the SCB, slide the ejector across the SCB horizontally, rotate it, and slide it again
another quarter of a turn. Turn the ejector again and repeat as necessary. Utilize the indexing feature
to maximize leverage and to avoid hitting any adjacent components.
•
Operate both ejector handles simultaneously. The insertion force on the SCB is too great for one ejector.
