SE7500CW2 Troubleshooting Guide - 5 - 08/21/02
Boot Issues
1) My server will not power on.
Check for the following possibilities:
• The SE7500CW2 server board requires an ATX +12V power supply. A momentary
switch should be used for the power on/off switch and the sleep/resume switch. The
power supply chosen must meet the ATX 2.01 or later specification. Does your power
supply meet these criteria?
• Have you securely plugged the server AC power cord into the power supply?
• Have you plugged the server into a “powered on” power strip?
• Some ATX power supplies have a power switch on the back of the power supply next to
the fan, is it switched on?
• Is the power supply set correctly to 110V or 235V depending on your power output?
• Is the front panel power switch cable properly connected to the front panel header pins
on the server board?
• Remove and reseat the memory modules. Try using memory modules from a known
working server system.
• Remove all add-in cards and see if the server boots using just the on-board
components. If successful, add the cards back in one at a time with a reboot in between
to see if you can pinpoint a suspect card.
• Remove the processor(s) and reseat it (them).
• Check to make sure chassis stand-offs are only located below mounting holes. Mis-
placed stand-offs can contact pins on the back of the board and cause a short which
could cause the system to not power on. Please consult the Intel Server Board
SE7500CW2 Product Guide that shipped on the SE7500CW2 Resource CD with your
board for details on correct stand-off placement.
Though it is unlikely that a server will not boot, there are many reasons why it may not
boot. If you are unable to resolve this issue, please fill out the customer support issue
report form (at the end of this document) and call your customer support representative.
Please note the answers to the following questions below.
• What memory is the server using? Is it on the tested memory list? Visit the Intel support
site for an updated memory list:
http://support.intel.com/support/motherboards/server/SE7500CW2.
• What processors is the server using? Is (are) it (they) on the tested list? Visit the Intel
support site for information on the supported processors.

• What chassis and power supply is the server using?
• If you are using a chassis with front panel lights, are there any front panel lights on?
• Is the power supply fan spinning?
• Does the system beep? See Issue 2.
• Please note what is displayed on the monitor or any sounds emanating from the server
system.
