CAUTION: Before you connect power to the switch, 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 switch (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 switch chassis to connect to the
earth ground. For instructions on connecting earth ground, see Connect the QFX5110
to Earth Ground.
On AC systems, the switch gains additional grounding when you plug the power
supply in the switch into a grounded AC power outlet by using the AC power cord
appropriate for your geographical location (see QFX5110 AC Power Supply Description).
CAUTION:
•
Install the power supply in the chassis. For instructions on installing a power supply in a QFX5110, see
Installing a Power Supply in a QFX5110.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect AC power to a QFX5110:
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 that a blank cover panel is installed over the second power supply
slot.
3. Locate the power cord or cords shipped with the switch; the cords have plugs appropriate for your
geographical location. See QFX5110 AC Power Specifications.
WARNING: Ensure that the power cord does not block access to device components
or drape where people can trip on it.
