Getting Started

Step 1. Installing your hard drives

WARNING! In order to prepare your drives for network operation, this enclosure will configure newly installed drives into an acceptable format (exFAT). Please be aware that any data currently on the drives may be lost during this process. It is recommended that you back up all data prior to installing any drives.

1. Using a Phillips head screw driver (not included) remove the screw from the bottom of the enclosure.

Step 2. Set your RAID Configuration

WARNING! In order to prepare your drives for RAID and Network operation, this enclosure will configure newly installed drives into an acceptable format (exFAT). Please be aware that any data currently on the drives may be lost during this process. It is recommended that you back up all data prior to setting your RAID configuration.

Note: While RAID configuration can be done at any time, we recommending setting your RAID configuration before initially connecting to your Network.

1. Ensure the unit is powerd off (main power switch at the rear of the housing is set to off).
2. Using the RAID switch on the back of the unit, set to your desired RAID configuration. (Available RAID Configurations)

1. Toggle the rear power switch to the on position then press and hold the "Set RAID button" as you power on the enclosure by pressing the "Front Power Button".
2. Once the enclosure has turned on, release the "Set RAID button". You may hear a buzzer sound from the enclosure as confirmation of the RAID change.
3. Your Desired RAID configuration is now set.

RAID Notes

If changing RAID configuraiton, ensure your enclosure is set back to STANDARD (JBOD), before setting to a different configuration.

JBOD is only supported in DAS connection or if you are using only one hard drive with the NAS., If connecting through NAS with two drives in JBOD, only one drive will be accessible.

If 2 hard drives are installed, JBOD mode cannot be supported in NAS mode.

Available RAID Configurations

The NAS enclosure supports 4 different RAID configurations. RAID is a storage technology that combines multiple hard drives into a single unit for secure data redundancy, increased volume size and/or improved performance.

Descriptions and benefits for each available RAID configuration are listed below:

Standard - JBOD

In JBOD, no RAID configuration is set and both drives appear as individual disks.

Note: JBOD is only supported in DAS connection, if connecting through NAS only one drive will be accessible.

Combine – BIG

In BIG, both drives appear together as a larger individual disk the size of both drives combined. This configuration enables you to create a larger volume than would be available using a single drive without the performance increase offered with RAID 0.

Mirroring - RAID1

In RAID1 both drives appear as an individual disk and data is written identically to both. This level protects your data from individual drive failure as a backup of all data is written instantly.

Striping - RAID0

In RAID0 both drives appear together as a larger individual disk the size of both drives combined. This level can improve your performance as read and write operations are performed in parallel on separate disks.

Step 3. NAS Setup

Note: NAS (Network) and DAS (USB 3.0) operation cannot be achieved simultaneously. If switching between DAS and NAS, the enclosure must be rebooted between operation modes. For the purpose of initial setup, we recommend you to set up the NAS first to avoid unnecessary system reboot and HDD re-format.

Method 1: Connect the NAS enclosure to your router (Quick Access)

1. Connect an Ethernet cable (included) from the LAN port on the enclosure to an available LAN port on your router.
2. Access the web interface by browsing the device name with your web browser:
   http://S352BMU3N

Note: Not all environments will support browsing by product name. In this case, you need to access your router to get the IP address assigned to your NAS Enclosure. (Please reference your router manual for further instruction)

Method 2: Connect the NAS enclosure directly to your computer (Standard Access)

1. Connect an Ethernet cable (included) from the LAN port on the enclosure to an available LAN port on your computer.
2. Set your computer IP address to an IP address on the same subnet as the NAS Enclosure.
3. The default NAS IP address is: 192.168.0.2
4. As a result for initial setup, we recommend setting your computer IP address to: 192.168.0.1
5. Access the web interface by browsing the NAS enclosure default IP address with your web browser: http://192.168.0.2
6. You can get access to your NAS enclosure at IP address 192.168.0.2

Step 4. Initialize Your Hard Drives

Access Web Interface

1. Open the web browser on the connected computer and type the NAS IP address, or device name into the address bar.

Default IP address: http://192.168.0.2

Default Device Name: http://S352BMU3N

1. The NAS Enclosure uses user accounts to limit access. An administration account is used for configuration and restricted access. You may be prompted to enter the NAS administration user name and password. By default the user name and password for the administration account are both “admin” as listed below.

Default Administration Account User name: admin

Default Administration Password: admin

Enter the user name and password and click the OK button.

Note: The administration account user name and password can be changed, and additional accounts can be added. (See: Our full manual online at StarTech.com - Page 64 )

1. You have now accessed the Web Interface Home page, as the "5 option" web GUI menu is displayed.

Hard Drive Initialization

WARNING! Newly installed drives will be formatted into an acceptable format for the NAS enclosure (exFAT). Please be aware that any data currently on the drives will be lost during this process. It is recommended that you back up all data prior to initial setup.

1. If this is the first time you've accessed your web interface, or your hard drives are otherwise not formatted, you will receive a message recommending you format your hard drives upon accessing the web interface.

The page at s352bmu3n says:

Hard disk not formatted, format it now?

This operation will format the hard disk and delete all data on the hard disk.

OK

Cancel

1. Click the OK button to format the installed drives into the supported exFAT format. You can also click Cancel if you wish to complete additional configuration steps before formatting the hard drive.

WARNING! Any data on the drives will be deleted upon format.

The page at s352bmu3n says:

Hard disk not formatted, format it now?
