The SEEPROMs operate off the 5.0V rail and are housed in 8-pin SOIC packages.
3.4.2.1.6 LED
Support
SC1400UP 1U SATA HSBP contains a green ACTIVITY LED and an amber FAULT LED for
each of the three drive connectors. The ACTIVITY LED is driven by the GEM424 or, for drives
that support the feature, by the SATA HD itself whenever the drive gets accessed. The FAULT
LED is driven by the GEM424 controller whenever an error condition is detected, as defined by
the firmware.
Activity and Fault LED functions are only available when a SATA host controller that supports
the SAF-TE protocol over I
2
C is connected to the SC1400UP 1U SATA HSBP via the SATA
Host I
2
C connector, J2A3.

Connector
The SATA backplane provides power for up to three ATA drives, and one floppy drive or CD-
ROM drive. A 6-pin power cable from the power supply harness is routed to the backplane and
plugs into a 2x3 shrouded plastic PC power connector. The following table provides the
connector pinout.

SATA Connectors (Backplane to Baseboard)
The SATA backplane has three 7-pin SATA connectors (Drive0, Drive1 and Drive2). These
connectors correspond to the SATA connectors on the Intel Server Board SE7221BK1-E
(SATA1, SATA2 and SATA3). The backplane connectors relay SATA signals from the
baseboard to the ATA drives. Each connector is used for a separate SATA channel and is
configured as a bus master. The following table provides the connector pinout.
