Frequently Asked Questions - Lockerstor 4RD Asustor
How do I install drives in the Lockerstor 4RD?
Open the drive tray handle, insert a 3.5" or 2.5" SATA drive into the tray, then slide the tray back into the bay until it clicks. Secure the tray with the lock and power on the NAS.
What RAID configurations are supported?
The Lockerstor 4RD supports RAID 0, 1, 5, 6, 10, and JBOD. Choose RAID 5 or 6 for a balance of capacity and data protection in a 4-bay setup.
How do I access the NAS from the internet?
Enable EZ-Connect or DDNS in the ADM software, then set up port forwarding on your router. You can also use Asustor's Cloud Connect service for secure remote access.
Can I expand the memory beyond 4GB?
Yes, the Lockerstor 4RD has a SO-DIMM slot that supports up to 64GB DDR4 memory. Open the case, replace the existing module or add a second one, and tighten the screws.
How do I reset the administrator password?
Press and hold the RESET button on the rear panel for 3 seconds. This will reset the admin password to 'admin' while preserving your data. For a full factory reset, hold for 10 seconds.
What are the benefits of the 10GbE ports?
The dual 10GbE ports provide ultra-fast network transfers, ideal for video editing, virtualization, and large backup jobs. Ensure your switch and cables support 10GbE to achieve full speed.
Which file systems can I use?
The NAS supports Btrfs and EXT4 for volumes, as well as network protocols like SMB, NFS, and AFP. Btrfs offers snapshots, data checksums, and advanced data protection.
Can I run Plex Media Server on this NAS?
Yes, install Plex Media Server from the ADM app store. With the Intel Atom processor and hardware transcoding capable, it can handle multiple 1080p streams, but 4K transcoding may require direct play.
How do I back up data from my PC?
Use Asustor Backup Plan for Windows, Time Machine for Mac, or set up a Rsync job for Linux. You can also schedule snapshots via Btrfs for point-in-time recovery.
Is hot-swapping supported?
Yes, the drive trays are hot-swappable. In a RAID 5 or 6 array, you can replace a failed drive without powering down the NAS. The system will automatically rebuild the array.
