5.5.9 Programmable pin 1 (Option Port Pin 9)

This pin can be used by a manufacturer for what ever purposes it desires within the specified definition, electrical characteristic and the availability of microcode. This pin is completely controlled by microcode. Refer to the "Option Pins" section of the Ultrastar X P ( D F H C ) S S A Models Interface Specification for a detailed functional description of this pin.

This pins is not accessible externally on CxB models.

5.5.10 Programmable pin 2 (Option Port Pin 10)

This pin is reserved and it is not connected to any internal logic.

This pins is not accessible externally on CxB models.

5.5.11 - Early Power Off Warning or Power Fail (Power Port Pin 11)

The Early Power Off Warning input pin on CxC models can be used to indicate to the drive that a power loss will occur by pulling this signal to ground. The input must provide a minimum of 6 milliseconds warning before power falls below operating specifications in order for the drive to stop its activities and handle the fault. Refer to the "Option Pins" section of the Ultrastar X P ( D F H C ) S S A Models Interface Specification for a detailed functional description of the fault handling associated with this pin..

This pin is not accessible on CxB models.

5.5.12 12V Charge and 5V Charge (Power Port pin 1 and 2)

These pins are longer than the others. They help to reduce current spikes during hot plug. Each pin require a resistor (not in the drive) in series between the power source and the drive connector. This allows for more controlled current draw as prior to other voltage pins. It is up to the subsystem to determine the proper resistance to add to these pins to meet the + / - 10% voltage drop limitations and the current draw limitation of the connector.

These pins are not accessible on CxB models

5.6 Front Jumper Connector

All models contain a jumper block (refer to Figure 14 on page 56) that is reserved for IBM Engineering use only.
