Statement 1071

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the device. To prevent static damage, discharge
static electricity from your body before you touch any of your system’s electronic components. You can
do so by touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

• When unpacking a static-sensitive component from its shipping carton, do not remove the

component from the antistatic packing material until you are ready to install the component in your
system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from
your body.

• When transporting a sensitive component, first place it in an antistatic container or packaging.

• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and

workbench pads.

Rack Installation Safety Guidelines

Before installing your device in a rack, review the following guidelines:

• Two or more people are required to install the device in a rack.

• Ensure that the room air temperature is below 95°F (35°C).

• Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.

• Plan the device installation starting from the bottom of the rack.

• Install the heaviest device in the bottom of the rack.

• Do not extend more than one device out of the rack at the same time.

• Remove the rack doors and side panels to provide easier access during installation.

• Connect the device to a properly grounded outlet.

• Do not overload the power outlet when installing multiple devices in the rack.

• Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices.

Introduction

Introduction

The WAE-611 supports two 1-inch (2.54-cm) slim 3.5-inch (8.89-cm) low voltage differential (LVD)
hard disk drives. The WAE-611 requires SCSI hard disk drives.

Warning

Required Tools

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

The following tools are required to perform the hard disk drive installation:

• Antistatic mat or foam pad to support and protect the removed hard disk drive

• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all

upgrade kits, field-replaceable units (FRUs), and spares

Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.

1029

Statement

Warning

The safety cover is an integral part of the product. Do not operate the unit without the safety cover
installed. Operating the unit without the cover in place will invalidate the safety approvals and pose
a risk of fire and electrical hazards.

Warning

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Statement 1

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

When installing or replacing the unit, the ground connection must always be made first and
disconnected last.

Statement 1046

To remove the bezel and cover, follow these steps:

Step 1 Review the information in the “Protecting Against Electrostatic Discharge” section on page 2.

Step 2 Power down the device and all attached devices. Disconnect the power cord and all external cables.

Step 3 Remove the bezel as shown in Figure 1.

a. Press the release tabs on the bezel and pull the bezel away from the chassis.

b. Store the bezel in a safe place.

Step 6 Before you begin working inside the chassis, familiarize yourself with the location of the components

that you will be handling. Figure 3 shows the front of the chassis and the location of the drive bays
behind the bezel.
