Safety and Warning

Observe the following safety instructions any time you are connecting or
disconnecting devices to the workstation.

WARNING: An electrical outlet that is not correctly wired could place

hazardous voltage on metal parts of the system or the devices that attach to
the system. It is the responsibility of the customer to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the power cables
for the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from
the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to pre­vent a possible shock from touching two surfaces with different electrical
potentials.

During an electrical storm, do not connect cables for display stations, print­ers, telephones, or station protectors for communications lines.

To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.

WARNING: This product is equipped with a three-wire power cable and

plug for the user’s safety. Use the power cable in conjunction with a prop­erly grounded electrical outlet to avoid electrical shock.

Static-Sensitive Devices

CAUTION: Motherboards, adapters, and disk drives are sensitive to static

electricity discharge. These devices are wrapped in antistatic bags to prevent
this damage. Take the following precautions:

• If you have an antistatic wrist strap available, use it while handling the
device.

• Do not remove the device from the antistatic bag until you are ready to
install the device in the system unit.

• With the device still in its antistatic bag, touch it to a metal frame of the
system.

• Grasp cards and boards by the edges. Hold drives by the frame. Avoid
touching the solder joints or pins.

• If you need to lay the device down while it is out of the antistatic bag,
lay it on the antistatic bag. Before picking it up again, touch the anti­static bag and the metal frame of the system unit at the same time.

• Handle the devices carefully in order to prevent permanent damage.

I. Introduction

Tools Required

A few items are needed to install or remove the components in this server.

• Phillips (cross) screwdriver

• Standard (flat) screwdriver

• Antistatic wrist strap

Preparation

1. Unpack your server, do not connect the power cord.

IMPORTANT: Most servers use an A T power supply that has a fixed ON

and OFF switch located on the front. This server uses an ATX power supply
that is normally OFF until an electrical signal is given to the power supply
through a momentary switch located on the front of the server. There is
always a standby power in the power supply in order for A TX power supply
features to work, and therefore removing the power cord is necessary to
prevent electrical shocks when working on the server components.

2. Unlock the padlock if one is used. This server is equipped with a lock­able front door to prevent unauthorized access. Open the side panel.

I. Introduction

3. Install final server components such as CPU, Memory , Hard Disk Drives,
expansion cards. Use this hardware reference guide along with your
motherboard manual in order to make these installations.

4. Connect a Keyboard and Mouse (purchased separately)

5. Connect a VGA-compatible monitor (purchased separately)

6. Connect a printer to the parallel port if desired.

7. Connect server to network (an optional network card is needed)

WARNING: To prevent electrical shock or fire, be sure not to plug tele-

communications/telephone cables into the network RJ45 connector in
the server if one is installed.

8. Set the power supply input voltage to either 115V for 110V-120V areas
or 130V for 120V-140V areas.

CAUTION: The voltage must be set correctly or damage may occur.

9. Connect the included power cord to the server’s power supply.

10.Connect the server to a grounded (three pronged) AC power source such
as a UPS or power strip (preferably with surge protection).

WARNING: This server is designed for connection to a grounded (earthed)

outlet. T o reduce the risk of electrical shock or damage to your server , do not
bypass the grounding plug.
