CAUTION:
a cable lug to the grounding and power cables that you supply. A cable with an incorrectly
attached lug can damage the router (for example, by causing a short circuit).
CAUTION:
You can mix DC and HVDC power supplies while swapping out one type for another
during installation.
CAUTION:
ensure proper operation, you must connect PTX10008 routers to earth ground before
you connect them to power. For installations that require a separate grounding conductor
to the chassis, use the protective earthing terminal on the router chassis to connect to
earth ground. For instructions on connecting a PTX10000 router to ground using a
separate grounding conductor, see
NOTE: The battery returns of the JNP10K-PWR-DC2 power supply must be connected as an
