5D-Link ShareCenter DNS-327L User Manual
Section 1 - Product Overview
Product Overview
The D-Link ShareCenter®DNS-327L is a 2-Bay Cloud Network Storage device. The cloud-centric network storage device
oers all the features a regular NAS oers but brings advanced data backup and storage to the Cloud. This is provided
through the“mydlink Account Management” console. The mydlink Cloud service oers complete data management of
les, music, photos, and video in the Cloud. So not only can you use the DNS-327L via the Cloud but you can also continue
accessing les through the internet using the built-in FTP server, web le server and the WebDAV protocol. Whether you are
allowing access locally or over the Internet, you can keep data safe by only giving rights to specic users or groups. Users
can also access their DNS-327L remotely using the mydlink™ portal, or by using the mydlink Access-NAS app on a mobile
phone or tablet. When conguring the DNS-327L, you can create and assign users and groups to folders with either read or
read/write permissions. This is ideal for an oce environment with employee-specic sensitive data, or for the home where
you can limit children’s access to certain material. The DNS-327L will be available to any computer (PC, Mac, or Linux) on
your network, without the need to install any software.
You may back up your music, photos, and video collections to the DNS-327L for safekeeping, as well as enjoy the benets
of the built-in UPnP AV media server as you stream digital content to compatible media players2(such as those found in
D-Link’s MediaLounge product line). This feature is highly convenient as it allows you to turn o a computer that would
normally be needed for the same function.
The availability of four dierent hard drive modes (Standard, JBOD, RAID 0, RAID 1) allows you to choose the conguration
best suited to your needs. Standard mode creates two separately accessible hard drives. JBOD combines both drives in
linear fashion for maximum space eciency. RAID 0 combines both drives in a ‘striped’conguration, which provides the
highest performance when using a Gigabit Ethernet connection. RAID 1 causes the drives to mirror each other, providing
maximum protection. If one drive fails while congured as RAID 1, the unaected drive continues to function as a single
drive until the failed drive is replaced. The new drive will then be re-mirrored, allowing the DNS-327L to return to its full
protective state.
The DNS-327L also has several add-on features to enhance your experience, including PhotoCenter, Blogging, Transmission
and Audio Streamer. The DNS-327L Cloud Network Storage enclosure also provides access to Google Drive. This allows you
to access, save and manage Google Apps like Google Docs, Google Spreadsheets, and Google Presentations to your NAS.
1 Hard Drive(s) not included.
2 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.

10D-Link ShareCenter DNS-327L User Manual
Section 1 - Product Overview
Checking the Hardware Requirements
To use your DNS-327L, you will need at least one hard drive installed. If you plan to use RAID 1, which protects your data
against failure of one hard drive, you will need to install two hard drives.
This section will help you:
• Select the appropriate hard drives
• Determine how much hard disk space you will need
• Ensure your data is protected
• Understand the basic requirements for a router or switch
Selecting hard drives:
You can use hard drives from any manufacturer and with any capacity with your DNS-327L. The D-Link ShareCenter supports
standard 3.5” internal SATA drives. If you are unsure, check with your administrator or hard drive retailer/manufacturer to
verify that your hard drives meet this standard
*Warning - Any pre-existing data on the drives will be erased during installation.
Determining how much hard drive space you need:
In order to protect your data from hard drive failure, your DNS-327L requires more space than what you will use for your data,
sometimes more than double the amount of space required. You should select hard drives that are larger in capacity than
your maximum storage requirements.
Using a Router or Switch:
If you are connecting your ShareCenter to a router or switch, your router or switch should support Gigabit Ethernet
(1000 Mbit/s) for maximum performance.The ShareCenter will auto-negotiate the highest connection speed available to your
router or switch. If you are using port bonding, use a managed switch.
Using an Uninterrupted Power Supply (UPS):
We highly recommend that you use your ShareCenter in conjunction with an Uninterrupted Power Supply (UPS), which will
protect against sudden data loss in power outages surges.

Getting Started
Hardware Setup
This user guide will help you get your ShareCenter set up in just a few steps. To install the ShareCenter on your local net-
work, refer to the steps below, or skip to “Zero Conguration Setup” on page 18 to run the setup wizard which will show you
how to install and congure your DNS-327L.
Release the top panel by rmly pressing the latch at the back.
Once the faceplate is unlatched, remove it to expose the hard drive bays.

16D-Link ShareCenter DNS-327L User Manual
Section 2 - Getting Started
Attach the hard drive brackets to the sides of your hard drives with the in-
cluded screws. Ensure the brackets are aligned so that when the hard drive is
inserted, the arrow on the bracket points to the front of the ShareCenter .
Insert up to two 3.5”SATA hard drives into the drive bays.
Note: Make sure to align the drive connector to the SATA connector at the
back edge inside the drive bay of the ShareCenter. Gently push the drive in
until it connects. When a drive is inserted properly, you will feel it“set” into
the connector. Some hard drives that are thin or oddly shaped may need to
be inserted carefully into position. If a drive is not properly set in place, the
hard drive LED will not illuminate after powering on the device.

17D-Link ShareCenter DNS-327L User Manual
Section 2 - Getting Started
Re-attach the top panel. Ensure the latch is inserted inside the panel.
Connect an Ethernet cable to the Ethernet port. This cable should connect
the ShareCenter to your local network via a router, switch, or directly to a
computer for conguration (cross-over cable required).
Connect the power adapter to the power receptor.

Zero Conguration Setup
If you have a mydlink-enabled cloud router (DIR-808L, DIR-810L, DIR-820L
DIR-850L, DIR-860L, DIR-868L, DIR-865L, DIR-855L, DIR-836L), you can take
advantage of Zero Conguration setup. Zero Conguration automatically
congures your NAS’s settings for you, and adds it to your mydlink account.
This type of setup allows you to set up your DNS-327L by simply plugging it
in and connecting it to your mydlink-enabled router.
Connect your NAS to your mydlink-enabled cloud router and Zero Congu-
ration will automatically congure your DNS-327L and automatically add it
to your mydlink account. After the short time it takes to do this you can re-
motely access your NAS from the www.mydlink.com website to manage and
monitor your DNS-327L.
Connect the Ethernet Cable
Use the included Ethernet cable and plug it into the DNS-327L. Plug the
other end into an available port on your router. If you wish to use your NAS
wirelessly, you will be able to remove the cable from the router after Zero
Conguration Setup is complete.
