The rebuild alarm tone functions differently. It remains ON during the rebuild. After the rebuild completes, an alarm with a different tone sounds to signal that the rebuild is complete. This is a one-time, non-repeating tone. LED Placement and Function The Intel® RAID Controller RS25NB008 contains the following LEDs: • One surface-mounted heartbeat LED (Green Color) to indicate SAS2208 activity. • Another surface-mounted system error LED (Amber Color) to indicate a board error. SAS/SATA Connectors The Intel® Integrated RAID controller RS25NB008 provides two external SFF-8088 SAS/SATA signal connectors. Each SFF-8088 connector provides support for four SAS/SATA ports. The sideband signals are configured to adhere to the SFF-8485 Specifications for SGPIO support. Figure 7. Intel® RAID Controller RS25NB008 SAS/SATA Connectors SAS/SATA Connector Pin-out Signal names are with respect to the host; the device connected to the host reverses the signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA connector is keyed at pin 1. These pin-outs for the serial ATA connector are not compatible with the legacy PATA connector. 16 Intel® RAID Controller RS25NB008 Hardware User's Guide

The rebuild alarm tone functions differently. It remains ON during the rebuild. After the
rebuild completes, an alarm with a different tone sounds to signal that the rebuild is
complete. This is a one-time, non-repeating tone.
LED Placement and Function
The Intel
®
RAID Controller RS25NB008 contains the following LEDs:
•
One surface-mounted heartbeat LED (Green Color) to indicate SAS2208 activity.
•
Another surface-mounted system error LED (Amber Color) to indicate a
board error.
SAS/SATA Connectors
The Intel
®
Integrated RAID controller RS25NB008 provides two external SFF-8088
SAS/SATA signal connectors. Each SFF-8088 connector provides support for four
SAS/SATA ports. The sideband signals are configured to adhere to the SFF-8485
Specifications for SGPIO support.

SAS/SATA Connector Pin-out
Signal names are with respect to the host; the device connected to the host reverses the
signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA
connector is keyed at pin 1. These pin-outs for the serial ATA connector are not
compatible with the legacy PATA connector.
