System Boot Failure; Memory Errors; Losing The System Setup Configuration - Supermicro SuperServer SYS-211TP-HPTR User Manual

System Boot Failure

If the system does not display Power-On-Self-Test (POST) or does not respond after the
power is turned on, check the following:
1. Remove all components from the motherboard, especially the DIMM modules.
2. 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 are properly
installed. See Chapter 2 for installation instructions. (For memory compatibility, refer
to the "Tested Memory List" link on the motherboard's product page to see a list of
supported memory.)
2. Check if all memory modules are populated with same type and speed.
3. Check for bad DIMM modules or slots by swapping a single module among all memory
slots and check the results.

Losing the System Setup Configuration

1. Make sure that you are using a high-quality power supply. A poor-quality power supply
may cause the system to lose the CMOS setup information. Refer to Chapter 1 for
details on recommended power supplies.
2. The coin battery on your motherboard may be old. Check to verify that it still supplies
approximately 3 VDC. If it does not, replace it with a new one.
