Troubleshooting
This chapter provides you a few useful tips to quickly get your ROBO-8712VLA
running with no failure. As basic hardware installation has been addressed in
Chapter 3, this chapter will basically focus on system integration issues, in terms of
backplane setup, BIOS setting, and OS diagnostics.
5.1 Backplane
Setup
Backplane
ROBO-8712VLA is a full-sized SBC, and therefore is only able to run on PICMG
PCI/ISA Backplane.
P4 Power connector
ROBO-8712VLA requires power drawing from at least two connectors. The CPU
supplementary power connector (J26) should be connected at all time for this P4
system to run properly. At its standalone mode, the single board computer will
connect no peripheral device cards. 4-pin connector for CPU (J26) and the 4pin
connector (J31) must be connected. If the system’s main power comes from a
backplane, the CPU supplementary power connector (J26) should still be connected.
ATX power
ROBO-8712VLA is designed to also support ATX mode. Please refer to the following
instruction to apply ATX power on your ROBO-8712VLA and backplane.
Step1: Remove the jumper on pin3 and pin4 of ATX P/S CONTROL CONNECTOR
(4-pin) connector (see the Figure below).
