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
on page 64. 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
Supply" on page
Install the power supply in the chassis. For instructions on installing a power supply in
a QFX5200, see "Installing a Power Supply in a QFX5200" on page
NOTE: Each power supply must be connected to a dedicated power source
outlet.
