Basic system reset (3 sec)
Press the reset button for 3 seconds, a beep sound will be heard. The following settings are
reset to default:
System administration password: admin
TCP/IP configuration: Obtain the IP address settings automatically via DHCP
TCP/IP configuration: Disable Jumbo Frame
TCP/IP configuration: If port trunking is enabled (dual LAN models only), the port
trunking mode will be reset to “Active Backup (Failover)”.
System Port: 8080 (system service port)
Security Level: Low (Allow all connections)
VLAN will be disabled.
Service binding: All the NAS services run on all available network interfaces.
Advanced system reset (10 sec)
Press the reset button for 10 seconds; you will hear two beeps at the third and the tenth
seconds. The NAS will reset all the system settings to default as it does by web-based
system reset in “Control Panel” > “System Settings” > “Backup / Restore” > “Restore to
Factory Default” except all the data are reserved. The settings such as the users, user
groups, and the network share folders previously created will be cleared. To retrieve the old
data after the advanced system reset, create the same network share folders on the NAS
and the data will be accessible again.

much memory is currently in the system, log into QES/QTS as administrator and go to
“Control Panel” > “System Settings” > “System Status” to open the System Status window.
Under System Information, check for System memory or Total memory.
Carefully follow the steps below:
1. Power off the NAS. Wait for device to fully power down.
2. Disconnect power cord(s), network cable(s), and any other cables attached to the
device.
3. Before opening the NAS, wear an antistatic wrist strap and connect the crocodile clamp
to ground to prevent electrostatic discharge from damaging equipment.
4. Loosen the 2 screws on the back of the NAS located on the handle.
