Introduction
Introduction
The D-Link DNS-120 Network Storage Adapter connects USB drives* to the network,
and provides authorized users access to their files. You can connect up to two standalone
USB 2.0 hard drives or flash drives and instantly have access to all stored files.
The DNS-120 Network Storage Adapter can be configured so that your USB 1.1 or
USB 2.0 drives are accessible over the Internet, making it convenient to access your
files, even when you’re away.
With its built-in backup function, schedule full or incremental backups of important
information on the network. You can set up PC-to-drive or drive-to-drive backups. Either
way, an extra copy of your data remains on the USB drive connected to the DNS-120
and ready to take on the road at anytime.
The DNS-120 Network Storage Adapter does not require you to reboot the system
when adding USB drives to the network, thus eliminating downtime. You can also
prevent any data loss by safely removing the USB drives using the “Disconnect” button
on the back of the DNS-120.
Through plug and play setup, installing the DNS-120 Network Storage Adapter into
your network has never been easier. Simply connect the DNS-120 to a Fast Ethernet
port on your network router or switch, and plug in USB hard drives or flash drives.
Additional setup options can be configured using the built-in Web-based admin
utility including firmware upgrade, user account management, folder management,
scheduled downloads, and DHCP/manual network settings. Using the Easy Search
utility, discover all DNS-120 units on the network and easily create shortcuts to their
USB drives.
The DNS-120 Network Storage Adapter is a fast, simple, and cost-effective way to
connect and share storage on the network.
* USB drives sold separately.
