I replaced the CPU to increase the specs of the NAS.
However, after replacing the CPU, the OS did not boot.
Condition
The message "Happy hacking" is displayed and then blacked out.
After that, I opened Web GUI with Chrome and tried whether it was possible to connect, but it timed out.
When I checked the NIC, I found that both the LED indicators were not shining and were not linked up.
When it returned to the original CPU, it started normally.
What on earth could be the cause of this?
