Replacing An Mx960 Dc Power Supply Cable - Juniper MX960 Hardware Manual

3. Insert the power cord plug into an external AC power source receptacle.
NOTE: Each power supply must be connected to a dedicated AC power feed and a
dedicated customer site circuit breaker. We recommend that you use a 15 A (250 VAC)
minimum, or as required by local code.
NOTE: For the high-capacity second-generation AC power supply, use a screwdriver to
tighten the screw on the AC receptacle retainer to prevent the AC power cord from getting
lose.
4. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and
access to router components, or drape where people could trip on it.
5. Move the AC input switch in the chassis above the power supply to the on (—)position and observe
the status LEDs on the power supply faceplate. If the power supply is correctly installed and functioning
normally, the AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
