Powering On and Off the Router

Powering On and Off the Router


Before you power on the router, check and ensure the following:

  • The power adapter is correctly connected.
  • The input voltage is in the range of 90 V AC to 264 V AC.


  • Power on the router.

    Turn on the power switch of the power supply system, and then turn on the power switch on the router to start the router.

    After the router starts, check the STATUS indicator of the power module first. If this indicator is in normal state, check the other indicators of the router. Figure 6-13 describes the indicator states when the router is running normally.
