Serial Ports
Two connectors, for the COM1
and COM2 serial ports,are
located on the P3TDLR board
(see Figure 5-8). COM1 is
located near USB1 connectors.
COM 2 is located near the
AMIBIOS (U33). See the mother-
board layout on page 5-10 for
locations. See Table 5-12 for pin
definitions.
Fan Headers*
There are several fan headers on
the P3TDLR that provide cooling
for various components. In addi-
tion to one fan header for each
processor, there are two over-
heat and two chassis fan head-
ers. When installed in the SC810
1U rackmount chassis, only the
main blower fan is used. The
blower fan should be connected to
the chassis fan header located
near the JF1 header. See the
motherboard layout on page 5-10
for locations. Refer to Table 5-11
for pin definitions.
Note: The maximum
current limitation for the onboard fans is 0.6
amps for each, not to exceed 1.25 amps for any
two fans. I.e. both CPU fans, both chassis fans
or both overheat fans.
