2. Product Overview

This chapter provides basic information about the QNAP ES1686dc NAS.

About the ES1686dc

The ES1686dc is designed to deliver a scalable platform for enterprise-level solutions. It is equipped with a powerful multi-core processor, AES-NI hardware encryption engine, and both USB 3.0 and 10GbE ports, allowing it to deliver optimal performance for enterprise users. The ES1686dc supports up to 16 storage drives. This number can be increased by attaching multiple expansion units. It has M.2 drive support and redundant storage controllers and power supplies to provide the necessary reliability, serviceability, and read/ write speeds.

Storage Controller Power Button

Operation User Action Result
Power on Press the button once. The storage controller powers on.
Power off Press and hold the button for 5 seconds. The storage controller powers off.
Force power off Press and hold the button for 10 seconds. The storage controller shuts down.
Warning
Use this method only when the storage controller is unresponsive. This action may result in data loss.

Reset Button

Operation User Action Result
Basic system reset Press and hold the
button for 3 seconds.
The following settings are set to default values.
• System administrator password: admin
Advanced system reset
Press and hold the button for 10 seconds.
• TCP/IP configuration:
• IP address settings: Automatically obtained via DHCP
• Jumbo frames: Disabled
• Port trunking mode: Failover (multi-LAN models only)
• Security level: Low (Allow all connections)
• LCD panel password: (blank)
• VLAN: Disabled
• Service binding: NAS services can run on any available network interface
The device performs a basic system reset. All default system settings are also restored, deleting all previously created users, user groups, and shared folders. The user data stored on the disks is retained. To retrieve data after an advanced system reset, recreate the previous folder structure on the NAS.

Battery Backup Unit

The battery backup unit (BBU) protects the data integrity of each storage controller. If both power supply units fail during a power outage, the system uses the BBUs for power and activates the asynchronous DRAM refresh (ADR) feature of the processors. While the BBUs supply power, cached data stored in the DRAM are written to the M.2 SSDs. This process is called Copy-to-Flash. Once power is restored and the system restarts, any logs, archives, or other important data are reconstructed from the data stored on the M. 2 SSDs.
Product Overview 17
Warning
During a power outage, do not remove storage controllers while their BBU status LEDs are orange. Removing a storage controller during this period interrupts the Copy-to-Flash process and may result in data loss.
