The D-Link ShareCenter® DNS-340L is a 4-Bay Cloud Network Storage device that oers all the features a regular NAS oers
but brings advanced data backup and storage to the Cloud. This is provided through the “mydlink Account Management”
console. The mydlink Cloud service oers complete data management of les, music, photos, and video in the Cloud. So
not only can you use the DNS-340L 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. Users can also access their DNS-340L remotely using the
mydlink™ portal, or by using the mydlink Access-NAS app on a mobile phone or tablet. When conguring the DNS-340L,
you can create and assign users and groups to folders with either read or read/write permissions. This is ideal for an oce
environment with employee-specic sensitive data, or for the home where you can limit children’s access to certain
material. The DNS-340L 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-340L for safekeeping, as well as enjoy the benets

of the built-in UPnP AV media server as you stream digital content to compatible media players
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 ve dierent hard drive modes (Standard, JBOD, RAID 0, RAID 1, RAID 5) allows you to choose the
conguration best suited to your needs. Standard mode creates two separately accessible hard drives. JBOD combines
both drives in linear fashion for maximum space eciency. RAID 0 combines both drives in a ‘striped’ conguration, which
provides the highest performance when using a Gigabit Ethernet connection. RAID 1 causes the drives to mirror each other,
providing maximum protection. RAID 5 is similar in function to RAID 1, but allows for a drive to fail and be replaced without
causing any downtime. The new drive will then be re-mirrored, allowing the DNS-340L to return to its full protective state.
The DNS-340L also has several add-on features to enhance your experience, including PhotoCenter, Blogging, Transmission,
Audio Streamer, and 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.

10D-Link ShareCenter DNS-340L User Manual
Section 1 - Product Overview
Checking the Hardware Requirements
To use your DNS-340L, 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-340L. 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-340L 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.

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
network, refer to the steps below, or skip to “Zero Conguration Setup” on page 18 to run the setup wizard which will
show you how to install and congure your DNS-340L.
Release the top panel by rmly sliding the top lid towards the back of the
unit.
Once the lid is unlatched, remove it to expose the hard drive bays.

Section 2 - Getting Started
Attach the hard drive brackets to the sides of your hard drives with the
included 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 four 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.

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 conguration (cross-over cable required).
Connect the power adapter to the power receptor.

Zero Conguration 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 Conguration setup. Zero Conguration automatically
congures your NAS’s settings for you, and adds it to your mydlink account.
This type of setup allows you to set up your DNS-340L by simply plugging it
in and connecting it to your mydlink-enabled router.
Connect your NAS to your mydlink-enabled cloud router and Zero
Conguration will automatically congure your DNS-340L and automatically
add it to your mydlink account. After the short time it takes to do this you can
remotely access your NAS from the www.mydlink.com website to manage
and monitor your DNS-340L.
Connect the Ethernet Cable
Use the included Ethernet cable and plug it into the DNS-340L. 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
Conguration Setup is complete.

After your DNS-340L is registered, you will be able to access all information
about the NAS from the cloud service. This information is already available
locally, but the mydlink service provides a way for you to view these details from
any location. From this location, you can view all physical disk information,
and congure RAID. Please be advised that conguring RAID over the mydlink
service will slow your system down and the speed of this service will depend
on your ISP and the speeds you are using to connect to mydlink.
If you have decided to format your NAS using mydlink, select the RAID method from the
drop-down list and the click the Format button. A pop-up message appears asking you
to conrm your choice to format the volume using mydlink. Click Yes to format, or No to
return to the menu.
The format process may take some time to complete. The format process depends on the
speed of your network connection and client CPU.
