Notes
- The minimum operating system is Solaris 8 4/01.
- System Controller slots are labeled SSC0 and SSC1.
- Pressing the Reset switch reloads the System Controller software
(attempting a SC reboot first is recommended).
- Resetting the System Controller with OBP >/=5.12 can bring down running
domains if the System Controller is performing a JTAG operation.
- Shut down running domains before resetting the System Controller.
- A System Controller reboot does not affect running domains.
- How To article 1005873.1 provides
a "ftp-only" shortcut for updating the flashprom firmware.
- To obtain the system serial number, use the SC command:
showplatform -p mac
