IMPORTANT: This chapter assumes that you have followed all previous instructions in this guide pertaining to physical installation and cabling of the chassis, its sub-components, and application and line cards.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.
|
1
|
When power is first applied to the chassis, or after a reboot, only the SPC in slots 8 and 9 receive power. Therefore, the SPCs 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.
|
|
2
|
During the startup process, each card performs a series of Power-On Self Tests (POSTs) to ensure that the hardware is operational.
|
|
3
|
If the SPC in slot 8 successfully executes all POSTs, it becomes the active SPC for the system. The SPC in slot 9 becomes the standby. Note that if there is a problem with the SPC in slot 8, the card in slot 9 becomes the active SPC.
|
|
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 SPCs.
|
|
5
|
The active SPC 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 SPC’s CompactFlash device.
|
The standby SPC observes the active card’s startup. If the file on the active card is loading normally, the standby SPC boots from the active card’s image. If the active SPC 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.
|
6
|
After the software image is loaded into the SPCs’ 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 SPCs are installed, or if they are installed incorrectly, no other card installed in the system will boot.|
7
|
Installed line cards remain in ready mode until their corresponding PAC is made active via configuration. Once the PAC 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.
|
9
|
After entering the standby mode, each of the PAC’s control processors communicate with the SPC to receive the appropriate code.
|
|
10
|
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 SPC 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. For additional information about system configuration files, refer to the Administration and Configuration Reference.
After the system successfully boots and the initial configuration is applied, the system is ready to be configured or offer services.
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.
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. |

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.

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.
|

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.
|
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 elapse prior to checking the LEDs on the various cards to verify the installation. Each PFU has a single status LED labeled POWER. This LED is green during normal operating conditions.
