BEHAVIOR

Status LED

Power: The CR4250 must be powered using an approved power source. Input requirements: 100-240V, 50-60Hz; 1.7A max without PoE, 4.1A max with PoE.

  • LED Off = normal operation

  • Blinking Green (1Hz) = upgrade in progress OR a button is currently pressed

  • Blinking Green (4Hz) = shutdown in progress

  • Blinking Orange (4Hz) = factory reset in progress

Power LED

  • Green = Powered ON and hardw are OK

  • No Light = Not receiving power. Check the power source connection

  • Red = Critical hardware problem detected. Hardware problem means that, most likely, unit can not boot. This can happen when hardware component (RAM, CPU, Flash, etc) was found to have a critical issue and can’t operate as expected. Contact Support.

  • Press and hold for more than 7 seconds. Unit will do the same thing as above, but will force shutdown of all components.

Reset Button

  • To reset the device, press and hold for more than 7 seconds (status LED will be flashing orange at 4Hz when button is released). Customer configuration will be erased and unit will reboot. Customer entitlements will be preserved.
