1. Introduction
LevelOne Network Storage GNS-4000 is a network attached storage (NAS) solution
for external storage targeted for small and medium business (SMB) users and small
office/home office (SOHO) users. With a NAS product, users can save their work
and have access to files over the network without having to carry around a disk
drive or memory stick. The Administrator can manage access privileges for greater
security. Multiple backup and synchronization functions protect your data.
The Network Storage GNS-4000’s architecture is based on the powerful Freescale
microprocessor and the hardware based Serial ATA RAID Controller. The Gigabit
Ethernet port is used for the data transfer and management. The USB ports are
used for a printer, expansion drives, and Uninterrupted Power Supply (UPS).

2. Chapter 2: Installation and Setup
Warning
The electronic components within the Network Storage are
sensitive to damage from Electro-Static Discharge (ESD).
Observe appropriate precautions at all times when handling the
Network Storage or its subassemblies.
Important
To configure the Network Storage, you must install the software
onto a PC running Windows Vista, 2003 Server, XP Professional,
or 2000.
2.1. Installing Disk Drives
You can populate the Network Storage GNS-4000 with SATA 1.5 Gb/s or 3.0 Gb/s
disk drives. For optimal performance, install disk drives of the same model and
capacity. Your disk drives will become a RAID Volume on the Network Storage.
To install disk drives:
1. Open the door on the front of the Network Storage enclosure.
2. Pull a disk drive carrier from the enclosure.
3. Carefully lay the disk drive into the drive carrier, so that the screw holes on the
sides of the carrier align with the screw holes in the drive.
4. Insert the screws through the holes in the drive carrier and into the sides of
the disk drive.
Install only the counter-sink screws supplied with the Network Storage.
Install four screws per drive.
Snug each screw. Be careful not to over-tighten.
5. Reinstall the drive carrier into the Network Storage enclosure.
Repeat steps 2 through 5 until all of your disk drives are installed.
6. Close the door on the front of the Network Storage.

8
2.2. Connecting to the Network
To connect the Network Storage to your network:
1. Attach one end of the network cable to the RJ45 network connection.
2. Attach the other end of the network cable to your Ethernet hub or switch
Important
If there are multiple networks at your facility, note the network to
which you connect the Network Storage. You will need this
information during the setup process.
2.3. Connecting the Power
To power the Network Storage:
1. Attach the power cord on the back of the Network Storage enclosure and plug
the other end into the power source
2. On the front of the Network Storage, press the power button
It takes about a minute to boot the Network Storage. When fully booted:
The System Status LED turns green
The buzzer beeps one time.

9
2.4. Installing the Software
