CAUTION: Before you connect power to the device, a licensed electrician must
attach a cable lug to the grounding and power cables that you supply. A cable with
an incorrectly attached lug can damage the device (for example, by causing a short
circuit).
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to earth ground before you connect
it to power. For installations that require a separate grounding conductor to the
chassis, use the protective earthing terminal on the device chassis to connect to the
earth ground. For instructions on connecting earth ground, see “Connecting Earth
Ground to a QFX3500 Device” on page 334 or “Connecting Earth Ground to QFX3600
or QFX3600-I Devices” on page 308. The device gains additional grounding when
you plug the power supply in the device into a grounded AC power outlet by using
the AC power cord appropriate for your geographical location (see “AC Power Cord
Specifications for a QFX Series Device” on page 154).

Install the power supply in the chassis. For instructions on installing a power supply in a QFX3500 device,
see “Installing a Power Supply in a QFX3500 Device” on page 453. For instructions on installing a power
supply in a QFX3600 or QFX3600-I device, see “Installing a Power Supply in a QFX3600 or QFX3600-I
Device” on page 447.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect AC power to a QFX3500, QFX3600, or QFX3600-I device:
1. Attach the grounding strap to your bare wrist and to a site ESD point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one
power supply is installed, ensure a that blank cover panel is installed over the second power supply
slot.
3. Locate the power cord or cords shipped with the device; the cords have plugs appropriate for your
geographical location. See “AC Power Cord Specifications for a QFX Series Device” on page 154.
WARNING: Ensure that the power cord does not block access to device components
or drape where people can trip on it.
