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

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

Cord Specifications for a QFX3008-I Interconnect Device with Three-Phase

Delta Wiring Trays" on page

Each wiring tray must be connected to a dedicated AC power source

Before you begin to connect power to the device:

Ensure that you understand how to prevent ESD damage. See

Electrostatic Discharge Damage" on page

Ensure that a licensed electrician has prepared the power cords. See

and Wye Three-Phase Power Cords" on page

Ensure that you have the following parts and tools available to connect power to the

Electrostatic discharge (ESD) grounding strap

Phillips (+) screwdriver, number 1

Slotted (–) screwdriver, 1/4 inch, with a torque range between 23 in-lb (2.6 Nm) and

25 in-lb (2.8 Nm)

You must use an appropriate torque-controlled tool to tighten

the screws on the terminal block. Applying excessive torque damages the

terminal block and the wiring tray. The absolute maximum torque that may

be applied to this screw is 50 in-lb (5.6 Nm).

Ensure that the power cords do not block access to device

components or drape where people can trip on them.
