IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. Use the statement number provided at the end of
each warning to locate its translation in the translated safety warnings that accompanied this

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.

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.
