■ If the reboot is scheduled to occur immediately, the router reboots. You
cannot access the J-Web interface until the router has restarted and the boot
sequence is complete. After the reboot is complete, refresh the browser
window to display the J-Web interface login page.
■ If the reboot is scheduled to occur in the future, the Reboot page displays
the time until reboot. You have the option to cancel the request by clicking
Cancel Reboot on the J-Web interface Reboot page.
■ If the router is halted, all software processes stop and you can access the
router through the console port only. Reboot the router by pressing any key
on the keyboard.
NOTE: If you cannot connect to the router through the console port, shut down the
router by pressing and holding the power button on the front panel until the
POWER
LED turns off. After the router has shut down, you can power on the router by pressing
the power button again. The
POWER LED lights during startup and remains steadily
green when the router is operating normally.
