That is an absolute classic IT nightmare scenario—often referred to in the trenches as a "resume-from-off failure." When enterprise or core networking gear runs continuously for years, the electrolytic capacitors quietly dry out, lose their capacitance, and develop high Equivalent Series Resistance (ESR) under constant thermal stress.
As long as they stay powered on, they just barely limp along. But the moment you cut power for maintenance or a rack move, the dielectric fails completely. When you try to cold-boot them, the inrush current fries them—and if you throw a fresh firmware update into that mix during the reboot sequence, the whole world sets on fire
Company's tend to run systems way past the EOL now to cut costs, then it bites them on the arse
