Frequently Asked Questions - A4SAN-E-WOHS Supermicro
How to access the NAS from my computer?
Connect the NAS to your network via Ethernet. Use the IP address assigned by DHCP (check router) or use the Supermicro NAS Finder utility. Open a web browser and enter http://
How to configure RAID?
After installing drives, log into the NAS web interface. Go to Storage Manager or RAID Configuration. Select the drives and choose RAID level (e.g., RAID 0, 1, 5, 10). Confirm to create the volume. Note that RAID 1 mirrors data for redundancy.
How to update the firmware?
Download the latest firmware from Supermicro support site. In the NAS web interface, go to System Update or Firmware Upgrade. Upload the file and follow prompts. Do not power off during update.
What are the default credentials?
Default username is admin and password is admin (or password). Check the label on the device. It is strongly recommended to change the password after first login.
Can I use SSDs instead of HDDs?
Yes, the NAS supports 2.5-inch SATA SSDs as well as 3.5-inch HDDs. SSDs offer faster performance but lower capacity. Ensure they are formatted correctly in the NAS interface.
How to set up a shared folder?
In the NAS web interface, go to File Sharing or Shared Folders. Create a new folder, set permissions (read/write for users). Enable protocols like SMB (for Windows) or AFP (for Mac). Map the drive on your computer.
What to do if the NAS is not detected on the network?
Check physical connections (Ethernet cable, power). Ensure the NAS LED indicators are on. Use a network scanner or the Supermicro utility to find the IP. If still not found, try a factory reset by pressing the reset button for 10 seconds.
How to replace a faulty hard drive?
If RAID is configured, remove the faulty drive from its bay. Insert a new drive of equal or larger size. The NAS will automatically rebuild the RAID. Check the RAID status in the web interface to monitor progress.
How to perform a factory reset?
Locate the reset button on the back panel. Press and hold for 10 seconds until the system beeps. This resets settings to defaults without deleting data. To wipe data, use the option in the web interface under System > Factory Reset.
How to enable remote access?
In the NAS web interface, go to Network > Remote Access. Enable Cloud Connect or Dynamic DNS. Configure port forwarding on your router for ports 80/443 or use a VPN for secure access. Always use strong passwords.
