Applying Power and Verifying the Installation

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 System Administration Guide.

Never operate the chassis if any slots are uncovered. This reduces airflow through the chassis and could

Caution

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.
