How to Install a JNP10K-PWR-DC2 Power Supply
The JNP10K-PWR-DC2 power supply in an MX10000 chassis is a hot-removable and hot-insertable
field-replaceable unit (FRU). You can install up to 6 power supplies in an MX10008 router chassis. All
HVDC power supplies install in the rear of the chassis in the slots along the left side of the chassis.
Before you install an HVDC 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.
WARNING: Protect yourself from severe burns by wearing heat-protective gloves when
removing a working HVDC power supply from the chassis. HVDC power supplies can
reach 158°F(70°C).
