C2SBA+II/C2SBA+/C2SBA/C2SBE User’s Manual
enhance clock control. A hardware-based component provides software-indepen-
dent thermal management that is compatible with the ACPI Revision 3.0a.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Wake-On-LAN (WOL)
Wake-On-LAN is dened as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN trafc is kept
to a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates of 1 GHz and faster.
The C2SBA+II/C2SBA+/C2SBA/C2SBE accommodates 12V ATX power
supplies. Although most power supplies generally meet the specications required
by the CPU, some are inadequate. A 2-Amp of current supply on a 5V Standby
rail is strongly recommended.
It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specication 1.1 or above. It is also required that the 12V
4-pin power connection (J41) be used for high-load congurations. In areas where
noisy power transmission is present, you may choose to install a line lter to shield
the computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.
