Version 2 of the Sun Fire™ System Controller board has increased capacities of
flash memory, dynamic memory, and non-volatile memory.
Note – Do not mix old and new versions of the System Controller (SC) board
in the same system. If a newer version of SC board fails over to an older
version of SC board, the larger quantity of data on the failed SC board can
overload the older version SC board, causing SC software features to terminate
unexpectedly.
Caution – The chassis AC power cord(s) must remain connected to
ensure a proper ground.
Caution – To avoid damaging internal circuits, do not disconnect or
connect any cable while the power is applied to the system.
Caution – The SC board and its modules have surface-mount
components that can be broken by flexing the board.
