Precautions for Using the SCC

The 1280 server contains a memory card called the System Configuration Card (SCC). This card contains the system's MAC address, serial number, and other configuration settings.

The SCC must be present and properly seated in the server at all times. The SCC can dislodge when the server is in transit. While this might not be visually obvious, it can be enough to prevent the server from booting. Before switching on the server for the first time, you should check the card to ensure that it is secured by the cable tie wrap and fully seated in the card reader.


If the SCC is removed from a working server, the server will shut down after 60 seconds. The server must be completely powered off or down to standby mode before the SCC can be removed or inserted.

Do not handle the SCC unless you need to transfer it to another system. If you need to handle it for this reason, avoid contact with the gold terminals on the underside of the card.

If the SCC is missing, the replacement SCC that is ordered will have a new host ID and MAC address. A replacement SCC with the existing host ID and MAC address can be obtained by contacting Sun Service. The new SCC will be programmed with the same host ID and MAC address from the customer's system. When the new card is inserted into the card reader, all of the TOD NVRAM and NVCI information gets copied over to the new SCC. The firmware automatically detects the previous information by checking a flag in the configuration data area on the card.

If the replacement SCC is an existing SCC from a different server, the TOD NVRAM and NVCI information from the reference server gets overwritten by the contents of the replacement SCC, and the system controller is reset, if necessary, to take the changes.
