Power on and off the MX304

Power on an AC-Powered or High Voltage AC/DC Powered MX304 Router

To power on an AC-powered or HVAC/DC-powered router:

  1. Verify that you fully insert the power supplies in the chassis.
  2. Verify that you securely insert each AC or HVAC/DC power cord into its appliance inlet.
  3. Verify that you connect an external management device to one of the Routing Engine ports (CON).
  4. Turn on power to the external management device.
  5. Switch on the dedicated customer-site circuit breakers for the power supplies. Follow the instructions for your site.
  6. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  7. Observe the status LED on each power supply faceplate. If an AC or HVAC/DC power supply is correctly installed and functioning normally, the status LED for each AC or HVAC/DC input switch lights steadily green.

    If the power supply status LED is amber or blinking, the power supply is not functioning normally. Repeat the installation and cabling procedures.

    Note:

    After powering off a power supply, wait at least 120 seconds before turning it back on. After powering on a power supply, wait at least 120 seconds before turning it off.

    If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, first issue the CLI request system halt command.

    After a power supply powers on, it can take up to 60 seconds for status indicators—such as the status LEDs on the power supply and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
  8. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

Power on a DC-Powered MX304 Router

To power on a DC-powered router:

  1. Verify that you connect an external management device to one of the Routing Engine ports (CON).
  2. Turn on power to the external management device.
  3. Verify that you connect the source power cables to the appropriate terminal: the positive (+) source cable to the return terminal (labeled RTN) and the negative (–) source cable to the input terminal (labeled –48V/-60).
  4. Verify that you fully insert the power supplies in the chassis.
  5. Switch on the dedicated customer-site circuit breakers to provide power to the DC power cables.
  6. Check that the status LED on the power supply faceplate is lit steadily blue to verify that power is present.
  7. If power is not present:

    • Verify that you correctly install the fuse, and turn on the breaker at the battery distribution fuse board or fuse bay.

    • Check the voltage with a meter at the terminals of the power supply for correct voltage level and polarity.

  8. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  9. Observe the status LED on each power supply faceplate. If a DC power supply is correctly installed and functioning normally, the status LED lights blue steadily.

    If the status LED on the power supply is blinking Amber on or blinking, the power supply is not functioning normally. Repeat the installation and cabling procedures.

    Note:

    After powering off a power supply, wait at least 120 seconds before turning it back on. After powering on a power supply, wait at least 120 seconds before turning it off.

    If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, first issue the CLI request system halt command.

    After a power supply powers on, it can take up to 60 seconds for status indicators—such as the status LEDs on the power supply and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

  10. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

Power Off the MX304 Router

Note:

After powering off a power supply, wait at least 60 seconds before turning it back on.

To power off the router:

  1. On the external management device connected to the Routing Engine, issue the request system halt command.
  2. Wait until a message appears on the console confirming that the operating system has halted. For more information about the command, see the CLI Explorer.
  3. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  4. Switch off the power supply source.
