Intel® Integrated RAID Module RMT3PB080 and RMT3CB080 Hardware User’s Guide 21
Silencing the alarm is temporary. If the cause of failure still exists or if an additional
failure is detected, then the alarm sounds again when the system is rebooted. Disabling the
alarm is persistent across errors and reboots. When the alarm is disabled, a failure does not
cause it to sound until it is re-enabled.
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
®
Integrated RAID Module RMT3PB080 and RMT3CB080 contain the
following LEDs:
• One surface-mounted heartbeat LED (Green Color) to indicate SAS2208 activity.
• Another two surface-mounted system error LEDs (Amber Color) to indicate a
board error.
SAS/SATA Connectors
The Intel
®
Integrated RAID Module RMT3PB080 and RMT3CB080 provide two internal
SFF8087 SAS/SATA signal connectors. Each SFF8087 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.
