How to Install a JNP10K-PWR-DC Power Supply
The JNP10K-PWR-DC power supply in an MX10008 and MX10016 chassis is a hot-removable and
hot-insertable field-replaceable unit (FRU). You can install up to 6 JNP10K-PWR-DC power supplies in an
MX10008 router chassis and 10 in an MX10016 router chassis. All power supplies install in the rear of
the chassis in the slots along the left side of the chassis.
Before you install a JNP10K-PWR-DC power supply in the chassis, ensure that you have followed all safety
warnings and cautions:
WARNING: Before performing DC power procedures, ensure that power is removed
from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel
board that services the DC circuit, router the circuit breaker to the OFF position, and
tape the router handle of the circuit breaker in the OFF position.
CAUTION: Before you connect power to the router, a licensed electrician must attach
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: Do not mix AC and DC power supplies in the same chassis.
CAUTION: To meet safety and electromagnetic interference (EMI) requirements and to
ensure proper operation, you must connect MX10000 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 an MX10000 router to ground using a
separate grounding conductor, see “Connecting an MX10000 to Earth Ground” on page 160 .
