Juniper MX10004 - Connect DC Power to an MX10004 Router

1. Connect the router to earth ground (see "Connect the MX10004 Router to Earth Ground" on page
135).
CAUTION: To meet safety and electromagnec interference (EMI) requirements and to
ensure proper operaon, ground the MX10004 properly before you connect it to
power.
For installaons that require a separate grounding conductor to the router's chassis,
use the protecve earthing terminal on the rear panel of the MX10004. Connect from
that terminal to the earth ground.
NOTE: An MX10004 router gets addional grounding when you plug the power supply in the
router into a grounded AC power outlet. Use the AC power cord appropriate for your
geographical locaon to make this connecon. See "MX10004 Power Cable Specicaons"
on page 44.
2. Install power supplies in the router and apply power. See "Install a JNP10K-PWR-AC2 Power Supply"
on page 148.
Connect DC Power to an MX10004 Router
Before you begin to connect power to the Juniper Networks MX10004 router, review how to prevent
electrostac discharge (ESD) damage. See "Prevenon of Electrostac Discharge Damage" on page 263.
The overall process of bringing up a DC-powered router involves the proper cabling of the individual
power supplies, adding the power supplies to the router, and supplying power. The power-on sequence
can start incrementally with a single power supply; however, we recommend that you use three or more
power supplies.
Each power supply input feed must be connected to a dedicated DC power source outlet.
To connect DC power to an MX10004 router:
1. Connect the router to earth ground (see "Connect the MX10004 Router to Earth Ground" on page
135).
2. To connect DC power to a JNP10K-PWR-DC2 power supply, see "Install a JNP10K-PWR-DC2
Power Supply" on page 154.
3. To connect HVDC power to a JNP10K-PWR-AC2 power supply, see "Install a JNP10K-PWR-AC2
Power Supply" on page 148.
