This article will walk you through the different scenarios of a non working Cable Node and the suggested troubleshooting steps
Suggested Cable Node Troubleshooting Steps
- Node went into a deep sleep mode, which will require a node reset: Putting the jumper back on for about 5 seconds and then remove it and verify that the node starts a blue and red flashing sequence ending in a red flashing sequence (flashing red 3 times every 55 seconds or so), and then proceed to map the cable node right away (see attached images showing the activation/deactivation procedure).
- Battery issues --> ran out of battery, in which case, it needs battery charge that can be achieved by deactivating the node for at least two days allowing for battery recharge. This is done by putting the red jumper back on for the suggested period of time (see attached images showing the activation/deactivation procedure). After, the proposed period of battery charge, remove the jumper, verify the node starts a blue and red flashing sequence ending in a red flashing sequence (flashing red 3 times every 55 seconds or so, then proceed to map the cable node right away. If the battery does not recover from this process, you can replace the node battery using these instructions:

- Less probable but still possible the node has gone bad, which will then require unit replacement: if after having reset or recharged the node's battery, the node does not show any signal of activation (flashing sequences) or stops the flashing sequence to early without having been mapped, then it would mean the node is a faulty unit.
