Juniper QFX10016, Hardware Manual

Page: 361 / 439

NOTE: Use the following procedure to power off a QFX10000.
Ensure that you have the following parts and tools available to power off the switch:
• An ESD grounding strap
• An external management device such as a PC
• An RJ-45 to DB-9 rollover cable to connect the external management device to the console port on
one of the Routing and Control Board (RCBs)
To power off a QFX10000:
1. Connect to the switch using one of the following methods:
• Connect a management device to the console (CON) port on a RCB by following the instructions
in Connect a Device to a Management Console Using an RJ-45 Connector .
• Connect a management device to one of the two management (MGMT) ports on the RCB by
following the instructions in 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:
