Step Two: Set up Your storage system

Setting up your storage system consists of the following steps:
Installing the Hard Disks
Attaching USB Devices
Connecting the Storage System to the Network
Powering Up the Storage System
Installing the Hard Disks
If you have fewer than four hard disks in your storage system, you might want to add more at this time. You
can add disks later, but changing your disk configuration once the disks contain data might cause data
loss.
Note: The storage system must have at least one SATA hard disk with a capacity of at least 80
GB.
USRobotics strongly recommends that you install all the hard disks that you want to use in
the storage system at this time in order to avoid data loss.
USRobotics also recommends that you use 4 disks of the same size for optimum perfor-
mance.
