On all cnWave platforms, the Main (and Aux) port LEDS can be used to determine boot status and more, if / when they are visible.
Definitions
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
All Hardware variants
The information in this section applies to all hardware variants
Main Port Left LED RED
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 / V2000.
Notes: Boot time is extended if
- Recovery Mode is entered, see below
- software upgrade is underway
Main Port 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
Main Port 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
Main Port Left LED Green and Right LED RED

the information here only applies to V5000, V3000 and V2000
Aux Port Left LED
Indicates the Power-Over-Ethernet state
| Colour | POE Status |
|---|---|
| Off | PoE disabled |
| Red | PoE enabled not supplying |
| Green | PoE enabled and supplying |
Aux Port Right LED
Indicates the Ethernet negotiation outcome
| Colour | Ethernet status |
|---|---|
| Off | not negotiated |
| Red | negotiated at 100Mbps |
| Green | negotiated at 1Gbps (or 2.5Gbps for V2000) |
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)
