38 Netra 240 Server Service Manual • June 2004
System Configuration Card
The system configuration card (SCC) ships tied in place to prevent the card from
getting lost. The SCC contains a server’s unique network identity information,
including the MAC address and host ID (stored in the IDPROM), and the OpenBoot
PROM configuration (also known as NVRAM). For more on the NVRAM, see
Appendix C.
You can use the procedures in this section to either replace a faulty SCC or to swap
a server’s unique configuration information from one server to another.
If the system configuration card is faulty or lost, a replacement card can be obtained
from Sun Services. See
Appendix A for the system configuration card part number.
For more information on how to contact Sun Services, read the Netra 240 Server
Release Notes (817-3142).
The replacement system configuration card is not programmed with any OpenBoot
PROM and ALOM configurations. Upon initial insertion in the Netra 240 server, you
are prompted for confirmation that you wish to use the new card. It is then
configured with the default configuration for the server.
Caution – The system configuration card must be installed and in place at all times
while the system is running. If you remove a system configuration card while the
system is running, the system powers off within 30 seconds.
Caution – Avoid contact with the gold terminals on the underside of the card.
Caution – Never remove the system configuration card while the server is booting
or running the Solaris software. Before removing or inserting the system
configuration card, remove power from the server, or put it into Standby mode.
Removing a System Configuration Card
1. Power off the server.
See “Powering Off the Server” on page 22. If you are swapping configuration
information from one server to another, you must power off both servers before
proceeding.
2. Open the front bezel (FIGURE 3-1).
