Power Supply; Serial Port - Supermicro X13SEI-TF User Manual

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 where
noisy power transmission is present.
The X13SEI-TF/-F motherboard accommodates a 24-pin ATX power supply. Although most
power supplies generally meet the specifications required by the CPU, some are inadequate.
In addition, two 12V 8-pin power connection is also required to ensure adequate power supply
to the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use a
power supply that contains a 24-pin and an 8-pin power connector. Be sure to con-
nect the power supplies to the 24-pin power connector (JPWR1), and the 8-pin power
connectors (JPWR2 and JPWR3) on the motherboard. Failure in doing so may void
the manufacturer warranty on your power supply and motherboard.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or above.

1.7 Serial Port

The X13SEI-TF/-F motherboard supports one serial communication connection. COM1 Port
header can be used for input/output. The UART provides legacy speeds with a baud rate of
up to 115.2 Kbps as well as an advanced speed with baud rates of 250K, 500K, or 1Mb/s,
which support high-speed serial communication devices.
