Section 1 - Product Overview
Introduction
The D-Link DNS-321 2-Bay Network Storage Enclosure shares your documents, photos, music, and videos across
the network and on the Internet (via FTP server) so family members, friends, or employees can access them. This
enclosure, which can hold two 3.5” SATA hard drives of any capacity1, creates a central network point for backing up
valuable files. The built-in RAID 12 mirroring technology protects these files from drive failure. Other options such as
Standard, JBOD, and RAID 0 are also available.
The DNS-321 shares files over the Internet via the built-in FTP server3. Users and groups can be created and assigned
to folders with either read or read/write permissions. Quotas can be set per user or group to restrict space usage.
In addition, the DNS-321 can be used to stream photos, music, and videos to UPnP AV compatible network media
players4.
The included CD contains D-Link’s Easy Search Utility. This utility allows you to locate the DNS-321 on the network
and map drives to your computer. Backup software is also included on the CD. This software allows you to backup your
files from a computer to the DNS-321 manually, by a schedule, or in real-time. Real-time backups are a great way to
safeguard against unfortunate accidents that may result in the loss of important files.
Combining ease of use with practical and high performance features, the DNS-321 is an organized solution for any
network. Free up drive space on computers and centralize data on your network with the DNS-321 2-Bay Network
Storage Enclosure!
1 Hard Drive(s) not included.
2 RAID 1 mirroring requires the use of 2 internal SATA drives.
3 Note that use of an FTP Server to access files over the Internet does not provide for secure or encrypted transmissions.
4 D-Link cannot guarantee full compatibility or proper playback with all codecs. Playback capability depends on the codec support of the UPnP™ AV media player.

Installation
Hardware Setup
This section provides installation information for the DNS-321. To install the DNS-321 on your local network, refer to
the steps below:
1. Slide the faceplate up until it unlatches from the device.
2. Once the faceplate is unlatched, pull it off the device, exposing
the drive bays.

Section 2 - Installation
3. Insert a 3.5” SATA hard drive into an available drive
bay. Make sure to align the drive connector to the SATA
connector on the bottom edge inside the drive bay of the
DNS-321. Gently push the drive in until it connects. When
a drive is inserted properly, you will feel it “seat” into the
connector. Some hard drives that are thin or oddly shaped
may need to be guided carefully into position. If a drive
is not properly seated, the light will not illuminate after
powering on the device.
4. Attach the faceplate to the front of the device.

cable should connect the DNS-321 to your local network via a
router or switch, or directly to a computer for configuration.
6. Connect the power adapter to the power receptacle.

Easy Search Utility
When first powered on, during the initial boot sequence, the DNS-321 will wait to be assigned an IP address via DHCP.
If it does not receive a DHCP assigned IP address, by default it will have a self-assigned IP address of 192.168.0.32.
It is recommended to use the included D-Link Easy Search Utility when accessing and configuring the DNS-321 for
the first time. If you want to change the IP address before logging in or if you are unable to connect to the DNS-321
IP address, you can use the Easy Search Utility provided on the product CD to locate the device on your network and
make any needed changes.
