1 SATA drive activity LED is driven by both the backplane controller and
the Hard Drives
Problem In section 4.4.3 of Intel Server Chassis SR2400 Technical Product Specification
(TPS) and section 4.4.2.1.6 of Intel Server Chassis SR1400 Technical Product
Specification (TPS), the second sentence of the first paragraph will be updated
as "The LED on the SATA backplane is driven by both the backplane GEM424
controller and SATA drives themselves using pin 11 on the connector. Therefore
systems with newer SATA drives supporting pin 11 can support drive activity
regardless of what SATA controller is used."
Implication If using the onboard SATA controller of the baseboard, the Hard Drive will
determine if Activity LED is supported. Only newer SATA drives will have Pin 11
enabled to support drive activity monitoring. No drive activity will be displayed on
the Activity LED if using older SATA drives.
Status Doc. This will be added in a future release of Intel® Server Board SE7520JR2
TPS.
