Alternate Front Panel Power LED Header 
Figure 18, E shows the location of the alternate front panel power LED header.  Pins 1 
and 3 of this header duplicate the signals on pins 2 and 4 of the front panel header.  If 
your chassis has a three-pin power LED cable, connect it to this header.  Table 10 
shows
 the p
in assignments for the alternate front panel header.

3  Front panel LED-  Out 
 
Consumer IR (CIR) Headers 
The Desktop Board has two CIR headers: the receiver or input header (Figure 18, H) 
and the output or emitter header (Figure 18, F).  The receiver header consists of a 
filt
ered translated infrared input compliant with Microsoft CIR specifications and a 
“learning” infrared input.  The learning input is a high-pass input which the computer 
can use to “learn” to speak the infrared communication language of other user 
remotes.  The emitter header consists of two output ports which the computer can use 
to emulate “learned” infrared commands in order to control external electronic 
hardware. 
 
NOTE 
The Consumer IR option must be enabled in the system BIOS before it can 
function.  Press <F2> at boot to enter the system BIOS, and go to Advanced > 
Peripheral Configuration > Enhanced Consumer IR, and set this option to 
Enabled.  
Table 11 shows the pin assignments for the front pa
nel
 CIR receiver (input) header 
and Table 12 shows the pin assignments for the back panel
 CIR emitter (output) 
header.
