Powering Off a QFX3008-I Interconnect Device

• Ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
• Ensure that you do not need to forward traffic through the device.

• 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 (CON) port

1. Connect a management device to the console (CONSOLE) port on the master Control Board in the QFX3008-I Interconnect device. For instructions about connecting a management device to the console (CONSOLE) port, see Connecting a QFX Series Device to a Management Console.
2. Shut down the 16-port QSFP+ front cards in the QFX3008-I Interconnect devicef. Issue the request fpc offline operational mode CLI command.

   This command shuts down the front cards gracefully. As the front cards go offline, traffic will be routed to other QFX3008-I Interconnect devices in your QFX3000 QFabric system.

3. Shut down the Control Boards by issuing the request system halt both-routing-engines operational mode CLI command. This command shuts down the devices 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) after entering the command:

Please press any key to reboot.

   Caution: The final output of any version of the request system halt command is the “The operating system has halted. Please press any key to reboot” message. Wait at least 60 seconds after first seeing this message before following the instructions in Step 5 to power off the switch.

4. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
5. Set the wiring tray switch to the OFF (O) position. Observe the wiring tray LEDs. The power supply LEDs should turn off (appear unlit). Repeat this step for the second wiring tray.

Note: After you power off a wiring tray, wait for at least 60 seconds before you turn it back on. After you power on a wiring tray, wait for at least 60 seconds before you turn it back off.
