6.4 Enclosure Management Cabling for Passive Backplane
When using a rack-optimized system with a passive backplane and an add-in RAID card, you
must install an additional 3-pin cable between the RAID card and the backplane to enable fault
LED control. The cable is included with your integrated system or the backplane kit.
In Intel
®
Server System SR1600UR, the 3-pin white HBA connector on the passive backplane
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. In
these configurations, connecting a 3-pin I
2
C cable to the backplane may cause unexpected
system behavior.
