1-12 Sun Fire V210 and V240 Servers Administration Guide • December 2005
1.2.8 DVD-ROM Drive
The Sun Fire V210 and V240 servers contain a bay to accept an optional slimline
ATAPI DVD-ROM drive. The bay is located on the front panel and is accessed by
opening the bezel.
For information on DVD-ROM drive installation, see Section 2.6, “Removing and
Replacing the DVD Drive” on page 2-12 .
1.2.9 System Configuration Card
The system configuration card (SCC) is housed in a slot behind the front bezel, next
to the On/Standby switch (
FIGURE 1-4
). The card contains unique network identity
information, including the MAC address and host ID (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 does not boot.
■
If the content of the NVRAM section is invalid, the system is not initialized with
its default NVRAM configuration.
It is 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 Section 2.4, “Swapping a System Configuration Card
Between Servers” on page 2-6 .
