Packing a QFX3500 Device for Shipping
To pack a QFX3500 device for shipping:
1. Connect a management device to the console (CON) port in 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 285.
TIP: You can also 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 (C0 or C1) port,
see Connecting a QFX3500 Device to a Network for Out-of-Band
Management.
2. Shut down the QFX3500 device 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
shutdown) after entering the command:
Shutdown NOW!
