Development Board Features
The development board shares the power connector for both SATA ports. Due to this
only one of the serial ATA channel (Port1 by default) supports hot swapping capability.
Hot swap on Port 1 can be used only when the Port 4 is not used. Y-Power cable needs
to be connected first to the device on Port 1 before connecting the signal cable. When
hot swap is not desired, both Port 1 and Port 2 can be used. A jumper J7H1 is
provided to enable hot plug/removal on port-1. For jumper setting details refer to
Section 4.3.1, Table 18.
Note: The eSATA drives should be externally powered. Hence, there is no power supply
support for them on the motherboard

USB Connectors

ICH9M provides a total of twelve USB 2.0/1.1 ports. 6 USB ports (0, 2, 4, 6, 8, 10)
are connected to the back-panel I/O connector, 6 ports (1, 3, 5, 7, 9, 11) to the front-
panel I/O connector (of these ports, port 9 is also routed to Docking).
Four ports (0, 2, 4, and 6) are routed to a 4 stacked USB connector (J3A1) at the back
panel. The other 2 ports (8 and 10) are routed to the RJ45+Dual USB stacked
connector (J5A1) at the back panel.
Six USB ports are routed to USB 2X5 front panel headers: Port (1, 3) at J6H4, Port (5,
7) at J6H2 and Port (9, 11) at J6J1. The remaining one USB port is routed to docking
connector J9C2.
Note: The USB Port 9 is routed to the docking station interface by default. By changing the
straps near ICH9M Port 9 can be routed to the front panel header also. The advantage
of this scheme is that Port 9 can be tested on the motherboard without using the
docking card.
