8. Remove first the plastic, then the metal retaining nuts from the wire strain relief, and
place either the 90° connector or flat connector over the threaded portion of the wire
strain relief as shown in Figure 65 on page 242 or Figure 66 on page 242.
9. Screw first the metal, then the plastic retaining nuts on the threaded portion of the
wire strain relief to complete the assembly.
10. Route the wiring through the hole in the wiring tray, and using a number 2 Phillips (+)
screwdriver, attach the connector to the wiring tray using the screws and washers you
removed in Step 5.
TIP: If you are ready to make the wiring connections to the terminal block,
see “Connecting AC Power to a QFX3008-I Interconnect Device with
Three-Phase Delta Wiring Trays” on page 246 or “Connecting AC Power to
a QFX3008-I Interconnect Device with Three-Phase Wye Wiring Trays”
on page 250.
11. Repeat Step 3 through Step 10 for the other wiring tray.

Connecting AC Power to a QFX3008-I Interconnect Device with Three-Phase Delta
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
