Powering Off a QFX3100 Director Device

Power off a QFX3100 Director device when it needs to be removed from a rack or cabinet or when the device is not active and you want to save power.

• Ensure that you understand how to prevent electrostatic discharge damage. See Prevention of Electrostatic Discharge Damage.

• An external management device such as a PC connected to the management network.

To power off a QFX3100 Director device:

1. Log in to the QFX3100 Director device. See Gaining Access to the QFabric Switch Through the Default Partition.
2. Determine if the Director device you want to power off is the master or standby Director device by issuing the show fabric administration inventory director-group status operational mode command.
3. If the device you want to power off is the master Director device, issue the request fabric administration director-group change-master director-device director-device-name operational mode CLI command. The specified device becomes the new master Director device, and the previous master Director device becomes a backup Director device.
4. Press the power switch on the QFX3100 Director device rear panel to initiate a graceful shutdown.

   Note: Pressing the power switch momentarily either causes the system to power on or causes a graceful shutdown. Pressing the power switch for 4 seconds or longer causes an abrupt power shutdown.

5. Observe the power supply faceplate LEDs. The AC power supply LED should turn off.
6. On the external management device, you can monitor the shutdown process to ensure that the system shuts down properly.
