Connector J28 provides an additional on-board Ethernet status LED interface. The +3.3V power
supplied to this connector is protected by a 1 Amp fuse.
* This pin can be connected to the Disable signal on the PCIe Mini Card
SATA Interface
The Iguana provides two serial ATA (SATA) ports, which communicate at a rate of up to 3.0
GB/s (SATA 2). The SATA connectors at locations J11 and J12 are standard 7-pin straight
SATA connectors with friction latching. Power to SATA drives is supplied by the ATX power
supply. Note that the standard SATA drive power connector is different than the common 4-pin
Molex connector used on IDE drives. Most current ATX power supplies provide SATA
connectors, and many SATA drives provide both types of power connectors. If the power supply
you are using does not provide SATA connectors, adapters are available.
The blue LED at location D11 (upper right corner of the board as shown in Figure 7) lights with
disk activity on the SATA ports.
