• Included hard disk chassis brackets (4) and screws (8)
• Phillips screwdriver to attach chassis brackets to the
hard disk(s)

expand storage capacity by connecting USB drives).
Make sure that the USB device uses its own external
power adapter if it has one.
• Computer with Network Interface Card (NIC) and TCP/

• Network device such as a switch, router, or hub

Install Hard Drive
Once you install a hard drive on the NSA221 and create
a volume, all existing data on the disk will be erased. If
you want to install two hard drives and configure them
as a RAID volume, it is recommended to use the same
disk size and model for best performance.
The NSA221 must be turned off before you remove or
install hard drive(s).
Creating a volume formats the hard drives. All data
will be lost. Back up any files on the disk to another
location before you install the disk in the NSA221.
