Connect Dc Power To An Mx10004 Router - Juniper MX10004 Hardware Manual

1. Connect the router to earth ground (see
135).
CAUTION: To meet safety and electromagnetic interference (EMI) requirements and to
ensure proper operation, ground the MX10004 properly before you connect it to
power.
For installations that require a separate grounding conductor to the router's chassis,
use the protective earthing terminal on the rear panel of the MX10004. Connect from
that terminal to the earth ground.
NOTE: An MX10004 router gets additional 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 location to make this connection. See
on page 44.
2. Install power supplies in the router and apply power. See
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
electrostatic discharge (ESD) damage. See
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
135).
