Most sites distribute power through a main conduit that leads to frame-mounted power
distribution panels, one of which can be located at the top of the rack that houses the
device. An AC power cord connects each wiring tray to the power distribution panel.
WARNING: The QFX3008-I Interconnect device is pluggable type A equipment
installed in a restricted-access location. It has a separate protective earthing
terminal provided on the chassis in addition to the grounding pin of the power
supply cord. This separate protective earthing terminal must be permanently
connected to earth.
CAUTION: Power cords and cables must not block access to device
components or drape where people could trip on them.
Each three-phase AC wiring tray has a metal wiring compartment that contains the AC
terminal block and ground. There are two types of three-phase wiring trays:
delta
(three-wire) and wye (four-wire). The delta AC terminal block consists of three input
terminals labeled
L1
,
L2
, and
L3
, from top to bottom in the common three-phase naming
convention.
You must provide cords appropriate for your geographical location. The AC power cord
wires insert into the AC terminal block on the wiring tray.
