Intel® Server Board SE7525GP2 Tech Tips
Revision 1.5
21
Version A (Green PCB) – both signals are floating
Version B (Red PCB) – both signals are connected directly to 5V
Version C (Blue PCB) – both signals are floating
These two signals are connected to the 6300ESB I/O Bridge and are only 3.3V tolerant.
Version B of this adapter attempts to drive 5V on those two signals and could lead to damage to
the baseboard. The other two versions of this adapter leave those signals floating so they can
be either 3.3V or 5V depending on the system. Because of this, only version A and version C of
the Adaptec Fireconnect 4300 FireWire card are recommended for use with the SE7525GP2
server board.
