What does a status of A5 indicate for the Ruby2?

A status of A5 for the Ruby2 indicates that the device requires attention due to an issue with the operating memory, specifically that it may need to be replaced. This status is indicative of a hardware-related problem where the device is unable to function properly, necessitating a power down and potential replacement of the operating system memory to restore normal operation.

In contrast, other possible statuses like normal operation or waiting for a transaction would not result in an A5 status, as they reflect the device functioning correctly or being ready to process transactions. Additionally, a response indicating lost network communication would highlight connectivity issues rather than a direct problem with the device’s memory hardware.
