System Configuration Card and OpenBoot Configuration Parameters

This appendix provides information on the system configuration card (SCC) and the OpenBoot PROM configuration parameters stored on it. For more on the SCC, see System Configuration Card.

The system configuration card is housed in a slot behind the front bezel, next to the On/Standby button (see FIGURE C-1). The card contains unique network identity information, including the MAC address and hostid (stored in the IDPROM), and the OpenBoot PROM configuration (also known as NVRAM).

  FIGURE C-1 Location of the System Configuration Card

This figure shows the location of the system configuration card when it is inserted in its slot. The front bezel is open.

The server attempts to access the system configuration card while booting.

It is therefore essential that you store the system configuration card safely if you have to remove it from the server, and replace the card before restarting the system.

For more information, see System Configuration Card. passes
