Though it is unlikely that a server will not boot, the following are some of the possible reasons for failure to boot:
• Some ATX power supplies have a power switch on the back of the power supply next to
the fan. Is this switched on?
• Check for proper power cord connections. Some chassis allow the use of two power
cords and the system will not power on when a single cord is used and is plugged into
the wrong connector.
• Your RAID controller may require the addition of a memory module. Verify that the
module is included on the tested memory list for the RAID controller. The tested
memory list is available at http://support.intel.com/support/motherboards/server.
Remove and reseat the memory module if memory on the card is installed in a memory
socket.
• Remove all add-in cards, including the RAID controller. See if the server boots using
only the on-board components. If successful, add the cards back in one at a time,
rebooting between each addition. This will help you determine the card that is causing
the problem.
• The Intel RAID Controller requires additional power to run. Although the amount
required is minimal, it may cause the system to exceed the power available from the
system power supply. Failure to provide the correct power supply or sufficient output
from the power supply may result in a failure of the system to power on. Refer to the
server board’s Technical Product Specification to calculate the necessary power budget
for all installed devices that draw power. These devices may include the memory, disk
drives, and add in cards. Verify sufficient power exists to run the system.
• Examine the LEDs on card and compare them to the product documentation to
determine if the LEDs give an indication of the failure.
• Compare any RAID card beep codes to the codes outlined in the product documentation
to determine if the beep codes you hear give any indication of the failure.
If you are unable to resolve this issue, contact your customer support representative. Gather
the following information before making your phone call:
• The make and model server board and RAID controller are you using.
• The version of BIOS and firmware of the server board.
• The version of the firmware on the RAID controller.
• The PBA (Product Board Assembly) number on the board.
• The chassis and power supply the server is using.
• Note what is displayed on the monitor or any sounds emanating from the server system.
