Get to Know Your NAS
1.1 Overview
This User’s Guide covers the following models: NAS326, NAS520, NAS540, and NAS542.
Use the NAS as your own personal cloud. Here are some key features:
• Start using Zyxel NAS instantly with FindMe - Use Zyxel FindMe to discover your NAS on your home
network and get in control in under 15 seconds. Then do an easy installation with no need to install a
NAS utility.
• Access and share files from your NAS wherever you are - Using the Zyxel Drive mobile app makes it
easy.
• Create a shared cloud space for people without a NAS - Provide your cloud space for your friends or
family members when you share a folder from the NAS with the Zyxel Drive mobile app. Your friends
and family members don’t need to purchase an additional NAS - just install the Zyxel Drive mobile
app on their mobile devices.
• Protect your data from drive failure - The NAS’s RAID 1 capability clones contents from one drive to
another. If a drive is damaged or corrupted, you still have another drive to restore from or use.
• Get up and running quickly with the easy-to-use interface - The Zyxel NSM (NAS Station Management)
5.2 intelligent desktop provides a rich feature set of tools with an easy-to-understand GUI design to
help you get things done quickly. The multitasking capability through a multi-window interface
enables you to quickly get applications up and running.
• Check your NAS while you’re away - Even if you have several Zyxel NAS devices, visit the
myZyxelcloud Web portal from anywhere to see their health status at a glance.
• Stream multimedia contents to your big screen TV - Bring your favorite multimedia files on the NAS to
the big screen. Zyxel zCloud app lets you play your favorite videos, music, or photos on your big
screen with TV streaming devices such as Apple TV, Google Chromecast, Roku 3, and Amazon Fire TV;
or directly on smart TVs like those from Samsung and LG.
