An RJ-45 to DB-9 rollover cable to connect the external management device to the console port
To power off a QFX5110 switch:
1. Connect to the switch using one of the following methods:
•
Connect a management device to the console (CON) port on a QFX5110. For instructions about
connecting a management device to the console (CON) port, see Connect a Device to a Management
Console Using an RJ-45 Connector.
•
You can shut down the QFX5110 from a management device on your out-of-band management
network. For instructions about connecting a management device to the management (C0) port, see
Connect a Device to a Network for Out-of-Band Management.
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 switch 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:
System going down in 1 minute
*** System shutdown message from root@ ***
System going down in 30 seconds
*** FINAL System shutdown message from root@ ***
System going down IMMEDIATELY
