4 Solving Problems

This chapter helps you identify and solve problems that might occur while you are using the

system.

In the event you encounter an issue with your SKA4 baseboard, this chapter helps you trouble

shoot and identify possible problem areas. In some cases, you are directed to contact your

customer service representative.

Boot Issues

Issue 1: My server will not power on

Check for the following possibilities:

• Is the server AC power cord securely plugged into the power supply?

• Is the server plugged 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 front panel power switch cable properly connected to the front panel header pins on the

baseboard located at J9E3, pins 2 and 16?

• If you are using a SSI compliant power supply, make sure the proper power supply connector

is attached to the auxiliary signal connector. SSI power supplies require a 3-volt sense signal

to properly power on and have a special 5 pin by 2 row connector for that purpose. If that

connector is available with your power supply, make sure it is firmly seated in the Auxiliary

Signal connector located at J9B2 on the baseboard.

• 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 and terminator card and reseat them.

• Remove and reseat the memory modules. Try using memory modules from a known working

server system. Memory must be used in fours.

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 included customer support form and call

your customer support representative. Please note the answers to the following questions below.

• What memory is being used? Is it on the tested memory list? Contact your customer service

representative for the latest tested memory list.

• What chassis and power supply is being used?

• 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.
