There are three OLED screens (top to bottom): System Information; Hard Drive Status; and Server Status. If the network connection drops, the whole screen flashes a connection dropped message.
On the System Info screen, the drive icons flash to indicate access and the arrows between the two computers also flash to indicate network activity.
The Hard Drive Status shows space used and changes to show rebuild status during RAID resyncs or drive formatting.
The Server Status shows USB printer connection and up/down status for the UPnP AV, iTunes and FTP services.
