Connecting AC Power to a QFX3008-I Interconnect Device with Single-Phase Wiring
Trays
A QFX3008-I Interconnect device is configured with six AC power supplies 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 page 237 .
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 AC power cord appropriate for your geographical location. See
“AC Power
Cord Specifications for a QFX3008-I Interconnect Device with Single-Phase
Wiring Trays” on page 139
