Memory failure phenomenon

1. Pressing the boot button is invalid and the screen is black.

2. Power-on card self-test

3. The memory of system recognition becomes smaller.

4. Restart the device without any downtime.

Investigation mode

Troubleshooting method:

1. Start sequence detection

2. Replace the hard disk or detect the interface of the replacement hard disk

3. Detection of raid card settings

The device is not powered on (power, motherboard, CPU)

Card hardware self-test (memory, expansion card)

Boot into BIOS (hard disk, boot item)

Centralized management

Network awakening

First, the computer monitor does not prompt, the keyboard and mouse display light is not on, the fan rotates, open the main chassis to wipe the memory bar and try again, a long time, may enter some ash layer, if not return to the factory self-test BIOS

Second, if the server cannot be started, it cannot enter the interface and cannot be started when it comes to DHCP. You can try to restart after power outage.

Third, reflect the memory problem through the phenomenon

Unplugging the memory and reseating cannot be resolved. The error is that all installed memory cannot be accessed. The system shuts down. I haven't installed the system yet. New machine.

Memory error, error memory is located in the third memory of memory board 3. It is recommended to minimize the memory of each of the two memory boards, and then use the replacement method to detect the memory after the machine does not report an error.

Solution:

1. Unplug the memory board 1 (a set of memory boards)

2. Replace the memory
