Intel rms25cb080 [31/60] Led placement and function

Intel® Integrated RAID Module RMS25PB0x0 and RMS25CB0x0 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 RMS25PB080, RMS25PB040, RMS25CB080 and

RMS25CB040 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 RMS25PB080 and RMS25CB080 provide two

internal SFF8087 SAS/SATA signal connectors. The Intel

Integrated RAID Module

RMS25PB040 and RMS25CB040 provide one internal SFF8087 SAS/SATA signal

connector. 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.
