1. Connect to the device using one of the following methods:
•
Connect a management device to the console (CON) port on a QFX3500 device. For instructions
about connecting a management device to the console (CON) port, see “Connecting a QFX Series
Device to a Management Console” on page 293 .
•
If you are using the QFX3500 device as a standalone switch, you can shut down the QFX3500 device
from a management device on your out-of-band management network. For instructions about
connecting a management device to the management (CO or C1) port, see “Connect a Device to a
Network for Out-of-Band Management” on page 325 .
•
Shut down the QFX3500 device from a management device connected through the QFX3100 Director
device in a QFabric system. See request component login for information about gaining access to
individual devices in your QFabric system.
2. Shut down Junos OS from the external management device by issuing the request system halt
operational mode CLI command. This command shuts down the device gracefully and preserves system
state information. A message appears on the console, confirming that the operating system has halted.
You see the following output (or something similar, depending on the hardware being shut down) after
entering the command:
Shutdown NOW!
