Connecting AC Power to a QFX3008-I Interconnect Device with Three-Phase Wye
Wiring Trays
A QFX3008-I Interconnect device is configuredwith six AC powersupplies and two wiring
trays.
CAUTION: Mixing different types of wiring trays in the same chassis is not a
supported configuration.
CAUTION: To meet safety and electromagnetic interference (EMI)
requirements and to ensure proper operation, the QFX3008-I Interconnect
device must be adequately grounded before it is connected to power.
For installations that require a separate grounding conductor to the chassis,
use the protective earthing terminal on the QFX3008-I Interconnect device
to connect to earth ground. For instructions on connecting a QFX3008-I
Interconnect device to ground using a separate grounding conductor, see
“Connecting Earth Ground to a QFX3008-I Interconnect Device”on page237.
A QFX3008-I Interconnect device receives additional grounding when you
plug the power supply in the device into a grounded AC power outlet by using
the ACpower cord appropriate for your geographical location. See “AC Power
Cord Specifications for a QFX3008-I Interconnect Device with Three-Phase
Wye Wiring Trays” on page 142.
NOTE: Each wiring tray must be connected to a dedicated AC power source
outlet.
Before you begin to connect power to the device:
•
Ensure that you understand how to prevent ESD damage. See “Prevention of
Electrostatic Discharge Damage” on page 192.
•
Ensure that a licensed electrician has prepared the power cords. See “Preparing Delta
and Wye Three-Phase Power Cords” on page 241.
