> Applying Power and Verifying the Installation
> This chapter provides information and instructions for understanding the boot process, applying power to the chassis, and verifying that the installation was successful.
> Understanding the System Boot Process
> Before you apply power to the system, it is important that you understand the boot process and how the hardware components are brought on line.
> The following figure provides a flowchart that explains each step in the startup process.
> Boot Process Flowchart

> Step 1 | When power is first applied to the chassis, or after a reboot, only the SMC in slots 8 and 9 receive power. Therefore, the SMCs are the first cards to boot and their LEDs are the first to light up. Once the system confirms that cards are located in slots 8 and 9, power is quickly applied to the SPIOs in slots 24 and 25.

> Step 2 | During the startup process, each card performs a series of Power-On Self Tests (POSTs) to ensure that the hardware is operational.

> Step 3 | If the SMC in slot 8 successfully executes all POSTs, it becomes the active SMC for the system. The SMC in slot 9 becomes the standby. Note that if there is a problem with the SMC in slot 8, the card in slot 9 becomes the active SMC.

> Step 4 | Once the active and standby order is determined, the SPIO cards in slots 24 and 25 are placed into active and standby mode, determined by the direct mapping of the active and standby SMCs.

> Step 5 | The active SMC begins loading the operating system software image designated in the boot stack. The boot stack entries are contained in the boot.sys file that resides on the SMC’s CompactFlash device.

> Step 6 | The standby SMC observes the active card’s startup. If the file on the active card is loading normally, the standby SMC boots from the active card’s image. If the active SMC experiences a problem during this phase, the standby card loads its software image, designated by its own boot stack entry in its boot.sys file, and takes control of the system as the active card.

> Step 7 | After the software image is loaded into the SMCs’ RAM, the active card determines if other cards are installed in the chassis by applying power to the other slots and signalling them. If the chassis slot contains an application or line card, power is left on to that slot. All empty slots are powered off.

> Important: If no SMCs are installed, or if they are installed incorrectly, no other card installed in the system will boot.

> Step 8 | When power is applied to the installed packet processing cards and line cards, they each perform their own series of POSTs.

> Step 9 | After successful completion of the POSTs, each of the packet processing cards enter standby mode.

> Note that the redundant card for an XGLC in slot 17 would be installed in slot 32. Use only the upper slot number when referring to this card. Installed line cards remain in ready mode until their corresponding packet processing card is made active via configuration. Once the packet processing card is active, the line card installed in the upper-rear chassis slot behind the card is also made active. The line card installed in the lower-rear chassis slot behind the card enters the standby mode.

> Step 10 | After entering the standby mode, each of the packet processing card’s control processors communicate with the SMC to receive the appropriate code.

> Step 11 | 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 SMC 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.

> Step 12 | 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. For additional information about system configuration files, refer to the Administration and Configuration Reference.

> Caution: Do not operate the chassis if any slots are uncovered. This reduces airflow through the chassis and could cause it to overheat. Make sure a card or blanking panel is installed in every chassis slot at all times.
> 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
> Once you have properly connected all power and ground cables to the chassis according to the instructions in “Cabling the Power Filter Units”, follow the instructions below to apply power to the system.

> Step 1 | Connect a terminal to the Console port of the primary SPIO.

> Step 2 | Ensure that the circuit breakers on the system’s Power Filter Units (PFUs) are in the OFF position.

> Step 3 | Turn the power source on.

> Step 4 | Check the voltage level and polarity at the terminals for each PFU. Place the positive probe of a voltage meter on the -VDC terminal and the common probe of the meter on the RTN terminal. The meter should display a voltage approximately equal to that of power source.

> Step 5 | Power on the system PFUs.

> Step a | Optional. If the circuit breaker on your PFU is equipped with a locking clip, move the clip to the left unlocking the circuit breaker’s actuator.

> Step b | Flip the circuit breaker on the PFU to the ON position.

> Step c | Optional. If the circuit breaker on your PFU is equipped with a locking clip, lock the circuit breaker in place. Move the breaker’s locking clip to the left until the clip’s inside tang is recessed in the breaker’s actuator opening.

> Step d | Repeat step a through step c for the second PFU.

> Verifying the Installation
> When power is applied to the chassis, power is provided to the upper and lower fan trays, and every installed application and line card.
> Each PFU, application card, and line card installed in the chassis has light emitting diodes (LEDs) that indicate its status. This section describes how to interpret the LEDs to verify that all of the installed components are functioning properly.
> Important: As the system progresses through its boot process, some cards may have no immediate LED activity. Line cards have sporadic Link and Activity LED activity. It is recommended that you allow several minutes to elapse prior to checking the LEDs on the various cards to verify the installation.
> Checking the LED on the PFU(s)
> Each PFU has a single status LED labeled POWER. This LED is green during normal operating conditions.
> PFU Power LED
> If the LED is not green, use the following troubleshooting information to diagnose the problem.
> PFU Power LED States

> Color | Description | Troubleshooting
> Green | PFU powered with no errors detected | None needed.
> None | PFU is not receiving power | Verify that the power switch is in the ON position.
> Verify that the RTN and -VDC lugs are attached properly according to the instructions provided in this document.
> Verify that the ground lug is attached properly.
> Verify that the power source is on and is supplying the correct voltage and sufficient current.
> Check the cables from the power source to the rack for continuity.
> If a fuse panel is installed between the Power Distribution Frame (PDF) and the chassis, verify that the fuses are intact.
> If a fuse panel is installed between the PDF and the chassis, check the cables from the fuse panel to the chassis for continuity.
> If all of the above suggestions have been verified, then it is likely that the PFU is not functional. Please contact your service representative.
