Troubleshooting
This chapter provides a few useful tips to quickly get ROBO-8777VG2A running
with success. As basic hardware installation has been addressed in Chapter 2, this
chapter will primarily focus on system integration issues, in terms of BIOS setting,
and OS diagnostics.
5.1
Hardware Quick Installation
Backplane
ROBO-8777VG2A is a full-sized Signal Board Computer, and therefore is only able to
run on PICMG PCI/ISA backplane. To know whether your backplane is PICMG
PCI/ISA backplane, please contact with vendor or manufacturer.
P4 Power connector
ROBO-8777VG2A requires power drawing from at least one or two power
connectors (J10 and J50), depending on ATX power mode. The CPU supplementary
Power Connector (J10) has to be connected to a system all the time no matter using
AT or ATX mode. Otherwise, the system won’t boot up properly. In addition, the 4-
pin connector (J10) is only required at ATX mode due to the fact that 4-pin connector
provides 5V Stand-by from the backplane to the SBC. If J10 isn’t connected, it could
also causes system failed to boot up. J50 is manipulated power supply operation
through backplane, which still devotes 5Vsb to system.
Serial ATA Hard Disk employment
Each Serial ATA channel can only connect to one SATA hard disk at a time; there are
total four connectors, J20 and J21. The installation of Serial ATA is simpler and easier
than IDE, because SATA hard disk doesn’t require setting up Master and Slave,
which can reduce mistake of hardware installation. All you need to do is to plug in
two cables and enable SATA in System BIOS.
