    Powering On an AC-Powered EX9208 Switch

    Before you power on the switch, ensure that:

    Ensure that you have the following parts and tools available to power on the switch:

    To power on the switch:

    1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    2. Connect the external management device to the Ethernet management (<...>) port on the master RE module.
    3. Turn on the power to the external management device.
    4. Ensure that the power supplies are fully inserted in the chassis and that each of their handles is flush against the faceplate.
    5. Ensure that the source power cord is inserted securely into the appliance inlet for each AC power supply.
    6. Switch on the dedicated customer site circuit breakers for the power supplies. Follow the ESD and safety instructions for your site.
    7. Flip the AC input switch on the power supply to the on (|). Observe the power supply faceplate LEDs. If the power supply is installed correctly and functioning normally, the AC OK and DC OK LEDs glow steady green. The PS FAIL LED does not glow.
    8. Repeat Step 7 for the remaining power supplies installed in the switch.

      If any of the status LEDs indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.

    9. On the external management device, monitor the startup process to ensure that the system boots properly.

    Note: After you power on a power supply, wait for at least 60 seconds before you turn it off. After you power off a power supply, wait for at least 60 seconds before you turn it back on.

    If the system is completely powered off when you switch on a power supply, the RE module 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 you power on a power supply, it can take up to 60 seconds for status indicators such as power supply LEDs and the show chassis operational mode CLI command display to indicate that the power supply is functioning normally. Ignore any error indicators that might appear during the first 60 seconds.
