WARNING: The chassis is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
provided on the chassis. This separate protective earthing terminal must be
permanently connected to earth ground.
CAUTION: Mixing different types of wiring trays in the same chassis is not a
supported configuration.
The single-phase wiring tray has three appliance inlets. See

redundancy for the system.
The three-phase wiring trays have a terminal block specific to either standard delta or
standard wye wiring configurations. The power cords that you provide for the three-phase
wiring trays must be installed before you install the wiring trays. See
Specifications for a QFX3008-I Interconnect Device with Three-Phase Delta Wiring Trays"
on page 282 and "AC Power Specifications for a QFX3008-I Interconnect Device with
Three-Phase Wye Wiring Trays" on page
NOTE: To provide power feed redundancy, the three-phase wiring tray in slot
must be powered by a dedicated power feed derived from feed A,

and the wiring tray in slot
feed derived from feed B. This configuration provides the commonly deployed
A/B feed redundancy for the system.
You must install two wiring trays in a QFX3008-I Interconnect device. Wiring trays are
installed at the bottom of the chassis in slots labeled
