System Configuration Card (SCC)

The system configuration card is housed in a slot behind the front bezel, next to the
On/Standby switch (see
information, including the MAC address and hostid (known as the idprom), and the
OpenBoot™ PROM configuration (also known as nvram).
The server attempts to access the SCC while booting.
If a properly formatted card is not present in the reader, the system will not boot.
If the content of the nvram section is invalid, the system will be initialized with
its default nvram configuration.
If the content of the idprom section is invalid, OBP displays a warning message
and the system will not auto-boot Solaris. However, you can boot the system from
the ok prompt using the boot command.
It is therefore essential that you store the SCC safely if you have to remove it from
the server, and replace it before restarting the system.
For more information, see "Swapping the System Configuration Card Between
Servers" on page 25.
