11.4.7 Power The drive receives power (+3.3 volts, +5 volts and +12 volts) through the SAS device connector. Three +12 volt pins provide power to the drive, 2 short and 1 long. The current return for the +12 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. Two +3.3 volt pins provide power to the drive, 1 short and 1 long. The current return for the +3.3 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot plugging. 11.5 SIGNAL CHARACTERISTICS This section describes the electrical signal characteristics of the drive's input and output signals.

IGNAL CHARACTERISTICS

This section describes the electrical signal characteristics of the drive’s input and output signals. See Table 23 for signal type

and signal name information.

11.5.1

Ready LED Out

The Ready LED Out signal is driven by the drive as indicated in Table 25.

The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt

supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See

Table 26 for the output characteristics of the LED drive signals.
