Hardware Checks

The Gamma Carry has 2 LED indicators on the rear of the unit. One is the Thunderbolt™️ LED and the other is the Heartbeat LED.

Thunderbolt™️ LED:

In normal operation this is lit solid green when connected to a powered on computer. A flashing Thunderbolt™️ LED indicates there's a problem. To try and resolve the problem, try another port or swap out the Thunderbolt™️ 3 cable for a known good cable.

Heartbeat LED:

In normal operation this LED should flash.
