System Power-up

This chapter describes the boot process that occurs when the system is first powered up.

Important:

The system boot process is governed by StarOS licenses. Refer to Chassis Universal License Requirements for additional information on the effect licenses and card types have on the boot process.

This chapter includes the following sections:

System Boot Process

The boot process is initiated after power is applied to the chassis.
    Step 1   When power is first applied to the chassis, the MIO/UMIOs in slots 5 and 6 and all fan trays are the first to receive power. Once the software is running, power is then quickly applied to the remaining cards in the system.
    Important:

    The fans in the fan trays initially rotate at medium speed until the first MIO completes its boot up. If no MIO/UMIO boots successfully within a few minutes, the fan speed increases to 100%.

    Step 2   During the startup process, each card performs a series of Power-On Self Tests (POSTs) to ensure that the hardware is operational. These tests also verify that the card meets all license requirements to operate on this chassis.
    Step 3   If the MIO/UMIO in slot 5 successfully executes all POSTs, it becomes the active chassis management MIO/UMIO for the system. The MIO/UMIO in slot 6 becomes the standby.
    Important:

    If the MIO/UMIO in slot 5 fails to boot, the MIO/UMIO in slot 6 automatically becomes the active chassis management MIO.

    Step 4   The active MIO/UMIO begins loading the operating system software image that is designated in the boot stack. The boot stack entries are contained in the boot.sys file that resides on the MIO/UMIO's flash device. The standby MIO/UMIO observes the active card's startup. If the file on the active card is loading normally, the standby MIO/UMIO boots from the active card's image. If the active MIO/UMIO experiences a problem during this phase, the standby card loads its software image, that is designated by its own boot stack entry in its boot.sys file, and takes control of the system as the active card.
    Step 5   After the software image is loaded into MIO RAM, the active card determines if other cards are installed in the chassis by applying power to the other slots and signaling them. If the chassis slot contains a card, power is left on to that slot. All empty slots are powered off.
    Important:

    If no MIO/UMIOs are installed in slots 5 and 6 or if they both fail to boot, other cards in the system will not boot.

    Step 6   When power is applied to the other installed cards, they each perform their own series of POSTs.
    Important:

    After successful completion of the POSTs, each of the data processing cards enter standby mode. Installed DPC/UDPCs or DPC2/UDPC2s remain in standby mode until they are made active via configuration.

    Step 7   After entering the standby mode, each of the DPC/UDPC or DPC2/UDPC2 control processors communicate with the active chassis management MIO to receive the appropriate code.
    Step 8   Upon successful loading of the software image, the system loads a configuration file designated in the boot stack (boot.sys file). If this is the first time the system is powered on and there is no configuration file, the active MIO/UMIO invokes the system's Quick Setup Wizard. Use the Quick Setup Wizard to configure basic system parameters that enable the system to communicate across the management network. The Wizard creates a configuration file, saved as system.cfg, that can be used as a starting point for subsequent configurations. The system is configured by automatically applying the configuration file during any subsequent boot. After the system successfully boots and the initial configuration is applied, the system is ready to be configured or offer services.

    Applying Power to the Chassis

    With all power and ground cables connected, you apply power to the chassis by following the instructions below.


    Caution

    Never operate the chassis if any slots are uncovered. This reduces airflow through the chassis and could cause it to overheat. A card or blank panel must be installed in every chassis slot at all times.

      Step 1   If the top-front cover is installed on the chassis, remove the cover to access the PFU circuit breakers.
      Step 2   At the front of the chassis verify that the circuit breakers on the PFUs are in the OFF position.
      Step 3   Set the circuit breakers on the power distribution panel (PDP) to ON.
      Step 4   At the rear of the chassis, remove the plastic terminal cover to access the PFU input terminals.
      Step 5   Use a voltmeter to check the voltage level and polarity across the input terminals for each PFU. The meter should display a voltage approximately equal to that of the power source.
      Step 6   Turn ON all the circuit breakers on both PFUs.
      Step 7   Proceed to Verifying System Startup.
      Step 8   When the initial checks are completed, reinstall the covers removed in step 1 and step 4.

      Verifying System Startup

      When power is applied to the chassis, power is provided to the upper and lower fan trays, and every installed card.

      Light emitting diodes (LEDs) on all circuit cards and daughter cards indicate operating status.

      Important:

      As the system progresses through its boot process, LED activity will eventually occur on all cards. Allow several minutes to elapse prior to checking the status LEDs on the various cards.

      Checking PFU Status

      The blue LEDs above the circuit breakers on each PFU should all be ON.

      If all of the LEDs on a PFU are OFF, check the following:

      • The PFU is firmly seated in the midplane connectors.

      • All circuit breakers on the PFU are set to ON.

      • All circuit breakers for power feeds from the local power distribution panel are ON.

      • -48 VDC power is available from the PDF to the local PDP.

      If any LED is OFF, check the following:

      • PFU circuit breaker is ON.

      • Voltage is present at corresponding input terminal at rear of the PFU.

      • Cable connection at PFU terminals is secure.

      • Circuit breaker for the power feed from the local PDP is ON.

      • Cable connection at the PDP terminal is secure.
