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:

2. Near the front of the tray is a spacer containing four screws. Squeeze the tabs toward each other to remove the spacer from the tray.

3. With the flat edge of the spacer up and the screws facing a flat surface (such as a table or desk top), flex the sides of the spacer apart from each other to release the screws.

4. Make sure that the hard disk is a SATA disk. It should have a SATA connector similar to the following:

5. Slide the new hard disk into the tray (connector end down and toward the back of the tray), and fasten the screws on the sides of the tray:

6. Slide the hard disk and tray back into the storage system until it snaps into place.

User Guide

If you have fewer than four disks

, load the bottom trays first and leave the top tray or trays empty.

If you have four disks that are not the same size

and you intend to use RAID 10, USRobotics recommends that you load the disks in ascending order of disk capacity, starting with the smallest disk in the bottom slot (slot 1),

Notes:

• If you install a hard disk that was previously part of a RAID, it will rebuild automatically.

• If you later replace all of the disks with higher-capacity disks, you must format those disks.

For more information about disk configurations, see the

“Disk Configurations” on page 125.

7. Repeat steps 1 through 6 for each disk that you will use in your storage system.

Attaching USB Devices

If you have USB storage devices or printers, you can attach them to the USB ports on the back of the storage system.

Note:

USB hubs are not supported. In addition, any USB disk must be formatted before you use it with the storage system, and only the first partition of a FAT or FAT32 file system will be recognized. Do not attach the storage system directly to a USB port on a computer.

Connecting the Storage System to the Network

To connect your storage system to your network, insert one end of the supplied RJ-45 Ethernet cable into the Ethernet port on the back of the storage system. Then insert the other end into a network port.

Powering Up the Storage System

To power up the storage system, insert the power cable into the power connector on the back of the storage system and plug the other end into a power outlet.

Note:

USRobotics recommends that you plug the storage system into a surge protector or uninterruptible power supply to prevent damage to the system from power surges.

Once you have connected the power cable, make sure that the power switch on the back of the storage system is set to the on position. Then press and release the power button on the front of the storage system.

The power and Disk LEDs flash while the storage system is booting. Once the system has finished booting, the Disk LEDs stop flashing.

If the hard disk installation was successful, the Disk LED is blue. If there is a problem, the Disk LED is off.

If this occurs, shut down the system, remove and inspect the hard disk for any installation problem, and reinstall it. To shut down the system, press and hold the power button for approximately five seconds until the Disk LEDs start flashing. Then release the power button; the storage system will shut down after a short period.
