Board Configuration

Power Configurations Available:
Configuring Poseidon appropriately will guarantee your system to power on safely and reliably. This section will
help you configure the board once you have selected a power configuration option.
Power can be applied in one of three different ways:
1- Via an ATX power supply using the MOLEX connector CN9 on Poseidon and cable adapter 6981091.
2- With an AC adapter such as PS-5V-04 and cable adapter 6980193 via the DB9 connector on the PNL-PSD panel
board.
3- Or directly with PS-5V-04 via the MOLEX connector CN9 on Poseidon.
Additionally Poseidon provides the option of using the power button to power-up (ATX mode), or power-up as soon
as power is applied (ATX Bypass).

The table summarizes the configuration for each option. JP7 refers to the ATX jumper on Poseidon while JP1 refers
to the external power enable jumper on the panel board. To locate this jumper see the PNL-PSD panel board
description in the final section of this manual. The table indicates the pin numbers where one jumper must be
installed.
When powering the board using PS-5V-04 via the MOLEX connector and BOOT on power (ATX Bypass) is
desired, the wire leading to pin 5 should be removed. If this is your definitive configuration, you might consider
clipping the wire so that there is no electrical connection leading to 5Vstandby. To be certain of removing the
correct lead, see the power input connector on page 30.
The Poseidon board has the following jumper-selectable configuration options.
