Install the power supply in the chassis. See “Installing a Power Supply in a QFX3100
Director Device” on page 311.
NOTE: Each power supply must be connected to a dedicated power source
outlet to ensure power supply redundancy.
Ensure that you have the following parts and tools available:
•
A power cord appropriate for your geographical location
To connect AC power to a QFX3100 Director device:
1. Ensure that the power supplies are fully inserted in the QFX3100 Director device.
2. Locate the power cords shipped with the QFX3100 Director device; the cords have
plugs appropriate for your geographical location. See “AC Power Cord Specifications
for a QFX3100 Director Device” on page 135.
WARNING: Ensure that the powercord does not block access to QFX3100
Director device components or drape where people can trip on it.
3. Insert the coupler end of the power cord into the AC power cord inlet on the AC power
supply faceplate.
4. If the AC power source outlet has a power switch, set it to the OFF (O) position.
5. Insert the power cord plug into an AC power source outlet.
6. If the AC power source outlet has a power switch, set it to the ON (|) position.
7. Repeat these steps for the second AC power supply.
8. Press the power switch on the rear panel of the QFX3100 Director device to power on
the device.
NOTE: Momentarilypressing the powerswitch causes the system to power
on or causes a power event to the operating system, which causes a
graceful shutdown. Pressing the power switch for 4 seconds or longer
causes an abrupt power shutdown.
9. Verify that the power LED on the power supply is lit and is on steadily.
