No Video; System Boot Failure; Memory Errors - Supermicro X13SAN-H User Manual

No Video

1. See if the Onboard Power LED at LED1 is green. If the LED is off, check the "No
Power" section of this chapter. If the LED is red, check the "System Boot Failure"
section of this chapter.
2. If the power is on but you have no video, remove all add-on cards and cables.
3. Make sure the video cables are properly connected.

System Boot Failure

If the system does not display POST, the system does not respond after the power is turned
on, or LED1 is red, check the following:
1. Clear the CMOS settings by unplugging the power cord and jumping pins 3 and 5 on the
CMOS clear jumper (JPME2). Refer to Section 2-7 in Chapter 2.
2. Remove all components from the motherboard, especially the DIMM modules. Make
sure that system power is on and that memory error beeps are activated.
3. Turn on the system with only one DIMM module installed. If the system boots, check for
bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure
in this chapter.

Memory Errors

1. Make sure that the memory modules are compatible with the system and that the
DIMMs are properly and fully installed. Click on the Tested Memory List link on the
motherboard product page to see a list of supported memory.
2. Check if different speeds of DIMMs have been installed. It is strongly recommended that
you use the same RAM type and speed for all DIMMs in the system.
3. Make sure that you are using the correct type of DIMM modules recommended by the
manufacturer.
4. Check for bad DIMM modules or slots by swapping a single module among all memory
slots and check the results.
5. Make sure that all memory modules are fully seated in their slots. Follow the instructions
given in Section 2-4 in Chapter 2.
6. Follow the instructions given in the DIMM population tables listed in Section 2-4 to install
your memory modules.
