The activity LED functionality is controlled directly by the hard drives. This causes the LED to
function differently between SAS and SATA drives. The expected operation is outlined in the
following table.

6.5.2.3 Optional Two 2.5-inch Hard Drives
The SR2625 is capable of supporting two additional 2.5-inch non-hot-swap SAS/SATA hard
drives with the addition of an optionally installed drive cage and cables. The 2.5-inch fixed drive
assembly is installed in the default filler panel and consists of a hard drive cage, all required
mounting hardware, and all required cabling.
6.6 Enclosure Management Cabling for Passive Midplane
When using a rack-optimized system with a passive backplane or midplane and an add-in RAID
card, you must install an additional 3-pin cable between the RAID card and the backplane or
midplane to enable fault LED control. The cable is included with your integrated system or the
backplane or midplane kit.
In Intel
®
Server System SR2625URBRP, the 3-pin white HBA CONN connector on the passive
midplane should be used.
IMPORTANT: No cable is required for fault LED control when using the on-board SAS or SATA
RAID controller. No cable is required for fault LED control when using an active backplane or
midplane. In these configurations, connecting a 3-pin I
2
C cable to the backplane or midplane
may cause unexpected system behavior.
