3.29 CAN 5-Volt Enable (CN77)
Table 3-30 lists the pin signals of the CAN 5-Volt Enable jumper header, which provides
2 pins
with 0.079
" (2mm) pitch. The jumper header enables an additional 5 volts and ground for the
CAN header at CN50, pin 9.
NOTE: The shaded table cells denote Ground or Power. Default = open pins, no jumper
installed.
3.30 LPC / TPM Interface (CN78)
Table 3-31 lists the pin signals of the LPC / TPM Interface socket, which provides 20
pins, 2 rows,
with odd/even sequence (1, 2) and 0.100
"
(2.54mm)
pitch.
NOTE: The shaded table cells denote Ground or Power. The # symbol indicates the signal is
Active Low.
3.31 Fan Voltage Select (CN79)
Table 3-32 lists the pin signals of the Fan Voltage Select jumper header, which provides
3 pins,
single-row, with 0.079
" (2mm) pitch.
NOTE: The shaded table cells denote power or ground. Default = jumper installed on 2-3.
