| Problem | Possible Causes | Suggested Action |
|---|---|---|
| Power light doesn’t come on when the device is plugged in. | Power outlet or power strip isn’t working. | Try a different outlet or power strip. |
| HAL power cord is malfunctioning. | Replace the HAL power cord. | |
| Ethernet Link LED indicators do not come on after plugging the HAL into a network switch or connecting it directly to a computer. | HAL and/or network switch isn’t powered on. | Power on both devices. |
| Ethernet cable or crossover cable is broken. | Try a different cable. | |
| The port on the network switch isn’t working. | Try plugging the cable into a different port on the network switch. |
Displayed on the rear panel of the HAL are four status indicators for each connected RAD. If the HAL is communicating properly with a RAD, all four status indicators (Audio Rx, Audio Tx, Comm, and Power) should be on. The following table details possible causes and solutions for situations in which one or more of these indicators are off.
note: It is best to check these indicators in the following order: Power, Comm, Audio Tx, and Audio Rx. If the power isn’t working, nothing else will work. If the data communications (Comm) isn’t working, Audio Tx will not work. If Audio Tx isn’t working, Audio Rx will not work.
| HAL Rear Panel RAD Status | Possible Causes | Suggested Action | |||
|---|---|---|---|---|---|
| Power | Comm | Audio Tx | Audio Rx | ||
| OFF | OFF | OFF | OFF | The HAL is not powered. | Power on the HAL and wait for it to boot up. |
| A cable wired incorrectly is loading down the RAD power supply. | Use a cable tester to verify the wiring of the shielded CAT 5e cable. | ||||
| The cable is plugged into something other than a RAD. | If using a punch block, verify that the brown pair is properly punched. (Assuming T568B termination). | ||||
| The power supply on that RAD port is broken. | Plugging the RAD cable into some other device (like an Ethernet switch) may load down the RAD power supply causing the error. | ||||
| ON | OFF | OFF | ON/OFF | The twisted pair in the shielded CAT 5e cable that carries communications data is wired incorrectly or broken. | Use a cable tester to verify the wiring of the shielded CAT 5e cable. |
| If using a punch block, verify that the orange pair is properly punched (assuming T568B termination). | |||||
| ON | ON | OFF | OFF | The RAD is not receiving an audio stream from the HAL. | Use a cable tester to verify the wiring of the shielded CAT 5e cable. |
| If using a punch block, verify that the green pair is properly punched (assuming T568B termination). | |||||
| ON | ON | ON | OFF | The HAL is not receiving an audio stream from the RAD. | Use a cable tester to verify the wiring of the shielded CAT 5e cable. |
| If using a punch block, verify that the blue pair is properly punched (assuming T568B termination). | |||||
