In a situation where a server reboots randomly, the first step should be to check for any issues with the power supply. Random reboots can often be caused by intermittent power supply issues, which can be due to faulty power cables, loose connections, or problems with the power source itself. This is especially pertinent in environments like a paper mill where dust and debris might affect cable integrity. Since the issue occurs every other day and at random times, it's less likely to be caused by components that would typically fail due to overheating or other gradual issues (like RAM or CPU heat sink problems). Therefore, checking the power cables is the simplest and most direct first step to troubleshoot the issue.
