•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 263).
•
Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician
must attach a cable lug to the grounding and power cables thatyou 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 “Connecting Earth Ground to a QFX5100
Device” on page 170. 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 “AC
Power Supply for a QFX5100 Device” on page 47).
•
Install the power supply in the chassis. For instructions on installing a power supply in
a QFX5100 device, see “Installing a Power Supply in a QFX5100 Device” on page 202.
NOTE: Each power supply must be connected to a dedicated power source
outlet.
To connect AC power to a QFX5100 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 switch; the cords have plugs
appropriate for your geographical location. See “AC Power Cord Specifications for a
QFX Series Device” on page 80.
WARNING: Ensure that the power cord does not block access to device
components or drape where people can trip on it.
4. Connect each power supply to the power sources. Insert the coupler end of the power
cord into the AC power cord inlet on the AC power supply faceplate.
5. Push the power cord retainer onto the power cord (see Figure 56 on page 173 and
Figure 57 on page 173).
