Juniper MX10016, Hardware Manual

Page: 63 / 320

CAUTION: Before you install the router, ensure that a licensed electrician has attached
an appropriate grounding lug to the grounding cable that you supply. Using a grounding
cable with an incorrectly attached lug can damage the router.
NOTE: DC power supplies are shipped only in the redundant configuration of MX10016 routers.
For details about different chassis configurations, see “MX10016 Components and Configurations”
on page 31 .
Each JNP10K-PWR-DC power supply weighs approximately 6 lb (2.7 kg) and has two independent pairs
of DC input lugs (Input 1, RTN, –48V/–60V and Input 2, RTN, –48V/–60V) on the faceplate of the power
supply. Each inlet requires a dedicated DC power feed. Although each inlet provides sufficient input power
to provide full output, always connect to a dedicated DC power feed to provide redundancy. Only one
power feed is operational at a time.
DC power models employ an electronic A-B input selection. The MX10016 power system provides 2N
source redundancy. If one power source fails, the electronic A-B input selection routes the power supply
to the alternate source.
Each JNP10K-PWR-DC power supply has a power switch with international markings for on (|) and off
(O), a fan, and four LEDs on the faceplate that indicate the status of the power supply. See
Figure 27 on page 65 .
