problems:
1.
power and cooling systems——power supply,power cable and fan;
2. ports ,cables and connections——ports on the rear panel the router and the cables connected to them

Check
the working environment conditions to make sure it is not very hot and the
chassis intake and exhaut vent are clear. The operating temperature of the
router is 0--40 degree.
3 . If the router fails to boot , but the power LED is on , Check the power supply .
