Visible LEDs on cnWave platforms

On all cnWave platforms, the Main port LEDS can be used to determine boot status if / when they are visible.


If the cnWave device is lying on a horizontal surface, with the face with the mounting holes faced down to that surface, the LEDs are then in the orientation that is referred to for the remainder of this doc; i.e. Left LED is on the left, etc


The Left LED will light red soon after power is applied, it will remain red while the unit is booting which should take approx 60 seconds for a V1000 and approx 40 second for a V5000/V3000.

Notes: Boot time is extended if

  • Recovery Mode is entered, see below
  • software upgrade is underway

Left LED RED and Right LED RED:

Following a short power outage (approx 4 seconds), the cnWave unit will enter Recovery Mode ( Upon entry to Recovery Mode, the Right LED will light red in addition to the left. Upon exit of Recovery Mode, the Right LED will turn off. Boot will then continue with just the Left LED lit RED as above

Left LED Green:

Once boot has almost completed, the Left LED will light green. Soon after this, the unit should be manageable directly (ssh or https).

Note: While the system in now running, it may still take some time for the unit to form a wireless link after the Left LED has lit green

Cambium Support

If accessing Cambium Support where the LED behaviour is being quoted, it is recommended to record a video of the LEDs to provide to the support team. This will serve to confirm / measure timings and help notice potentially missed events (e.g. short green lights)
