Introduction
The D-Link DNS-321 ShareCenter™2-Bay Network Storage 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 up to 2TB each, creates a central network point for backing up valuable les. The built-in RAID 1 mirroring technology
protects these les from drive failure. Other options such as Standard, JBOD, and RAID 0 are also available.
The DNS-321 shares les over the Internet via the built-in FTP server. 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 players.
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 les from a computer to the
DNS-321 manually, or by a schedule.
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 ShareCenter™2-Bay Network Storage!

Basic 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:
3. Insert a 3.5” SATA hard drive into an available drive bay.
2. Once the faceplate is unlatched, pull it off the device, exposing
the drive bays.
1. Slide the faceplate up until it unlatches from the device.
4. Attach the faceplate to the front of the device.

Section 2 - Installation

D-Link DNS-321 User Manual
6. Connect the power adapter to the power receptacle.5. Connect an Ethernet cable to the available Ethernet port. This
cable should connect the DNS-321 to your local network via a
router or switch, or directly to a computer for conguration.
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.

Software Setup
When rst 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 conguring the DNS-321 for the rst 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.
