Serial Ports
Two connectors, for the COM1
and COM2 serial ports,are
located on the P3TDLR board
(see Figure 2-8). COM1 is
located near USB1 connectors.
COM 2 is located near the
AMIBIOS (U33). See the mother-
board layout on page 2-9 for
locations. See Table 2-12 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. If used, a blower fan should
be connected to the chassis fan
h e a d e r l o c a t e d n e a r t h e J F 1
header. See the motherboard lay-
o u t o n p a g e 2 - 9 f o r l o c a t i o n s .
Refer to Table 2-11 for pin defini-
tions.
Note: The maximum current limita-
tion 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 over-
heat fans.
