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 performance.
To install the hard disks, you need a Phillips head screwdriver.
1. Remove the top hard disk tray from the storage system:
