NOTE: The optional right-angle DC power cables, CBL-JNP-PWR-DSUB2
and CBL-JNP-PWR-DSUB3, do not include a ground connection wire.
Regardless which DC power cable you use, you must connect the QFX10002
to earth ground before you connect it to power, using the procedure described
in "Connecting DC Power to a QFX10002" on page
WARNING: For field-wiring connections, use copper conductors only.
WARNING: Power cables must not block access to QFX10002 components
or drape where people could trip on them.
CAUTION: You must ensure that power connections maintain the proper
polarity. The power source cables might be labeled
their polarity. There is no standard color coding for DC power cables. The
color coding used by the external DC power source at your site might be
different from the color coding for the leads on the DC power cable provided
with the chassis.
