Peripheral and Hard Drive Support
The power cable for this connector is provided with the Tape Drive Accessory Kit.
4.4.4.2 Redundant Fan Power Connector
The SATA backplane provides two pulse width modulated (PWM) power outputs to control the
optional bank of four system fans. Two control PWM inputs are generated from the baseboard's
LM93 health monitor IC and routed through the high density 100 pin Control Panel/Floppy/IDE
flex circuit interface. Two high frequency PWM amplifying circuits are located on the backplane
and the output is routed to a 2X5 pin header for the bank of redundant fans.

PWM 1 supports one system fan with max current of 1.5A. PWM 2 supports up to three system
fans with max current limit of 4.5A
4.4.4.3 SATA Connectors
The SATA backplane has five 7-pin SATA connectors. These connectors relay SATA signals
from the baseboard to the ATA drives. Each connector is used for a separate SATA channel
and is configured as a bus master. The following table provides the connector pinout.

Table 52. 7-Pin SATA Connector Pinout (J2, J3, J4, J5, J6)

4.4.4.4 Hot-Swap SATA Connectors to Drive
The SATA drive interface combines both SATA and power signals into a single connector. The
pin-out of the drive interface connector is the same as a standard ATA and power connector.
The following table provides the pinout.
