Example of the NAS in a Home Network
Above is the NAS in a home network. Users back up and share data on the NAS. The media player
plays the NAS’s media files on the TV. A USB hard drive provides extra storage space and files are
copied directly from the USB mass storage device to the NAS.
Place the NAS behind a firewall and/or IDP (Intrusion Detection and Prevention) device to protect it
from attacks from the Internet.
Refer to the Quick Start Guide for hardware connections and how to install and remove hard drives
from the disk trays.
Note: Turn off and disconnect the NAS before you install or remove the internal hard disk
or disks.
