Electrical Characteristics
All power is supplied to the adapter via the PCI Express 3.3V and 12V rail. Necessary
Voltages are provided by onboard switching regulator circuitry operating off of 12V and
3.3V rails.
The following states determine the typical current consumption of the board:
• State 1. During a hard reset
• State 2. During a disk stress test
• State 3. While sitting idle at the DOS prompt.
— Supply voltage = 12V +/- 8% (from PCI edge connector only)
— Supply voltage = 3.3V +/- 9% (from PCI edge connector only)
