Rack Mount Setup
Use the included rack mount hardware to install the unit according to the following
instructions.
DANGER:
A unit with installed drives can weigh more than 80 pounds. So as to
avoid injury or damage to the equipment, plan to perform the rack
mount installation with appropriate assistance.
Ambient Operating Temperature
If the unit installed in a closed or multi-unit rack assembly, the ambient operating temperature
of the rack environment might be greater than the ambient temperature of the room.
Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum rated ambient temperature found in "Default Settings and
Specifications" in Appendix A.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe
operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due
to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply
circuitry and the effect that any possible overloading of circuits might have on over current
protection and power supply wiring. Consider equipment nameplate ratings when addressing
this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the
direct connections to the branch circuit (for example, the use of power strips).

Chapter 1: Getting Started |9
ReadyNAS 4200 Hardware Manual
Choosing a Setup Location
Note: This product is intended for installation in a restricted access
location (dedicated equipment rooms, service closets, and the like)
only.
Leave enough clearance in front of the rack to enable you to open the front door completely
(about 25 inches) and approximately 30 inches of clearance in the back of the rack to allow
for sufficient airflow and ease in servicing.
Preparing for Setup
Read these instructions in their entirety before you begin. Locate the ReadyNAS 4200
shipping carton, remove the rack mounting kit and prepare to work with it.
Installing the System into a Rack
To install the system into a rack:
1. The rack mounting kit contains two rail assemblies. Each assembly consists of two
sections: an inner fixed chassis rail that secures directly to the ReadyNAS 4200 chassis
and an outer fixed rack rail that secures directly to the rack itself. Extend the rail
assembly by pulling it outward. Press the release tab and separate the inner rail from
the outer assembly.

trained personnel, according to the installation instructions provided with each unit.
2. The socket-outlet shall be installed near the equipment and shall be easily accessible.
3. Observe the onboard battery precautions. Follow the battery replacement instructions from
“Replacing the Onboard Battery” on page 30.
DANGER:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN
INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING
TO THEIR INSTRUCTIONS.
4. The units and their associated LAN connections shall be interconnected only with equipment
within the same building.
5. Slide or rail mounted equipment is not to be used as a shelf or a work space.
Electrical Safety Precautions
Follow basic electrical safety precautions to protect yourself from harm and the ReadyNAS
4200 from damage:
• Be aware of the locations of the power on/off switch on the chassis as well as the room's
emergency power-off switch, disconnection switch, or electrical outlet. If an electrical
accident occurs, you can then quickly remove power from the system.
• Do not work alone when working with high voltage components.
• Always disconnect power from the system when removing or installing main system
components, such as the main board or memory modules. When disconnecting power,
you should first power down the system with the operating system and then unplug the
power cords of all the power supply units in the system.
• When working around exposed electrical circuits, another person who is familiar with the
power-off controls should be nearby to switch off the power if necessary.
• Use only one hand when working with powered-on electrical equipment. This is to avoid
making a complete circuit, which will cause electrical shock. Use extreme caution when
using metal tools, which can easily damage any electrical components or circuit boards
they come into contact with.
• Do not use mats designed to decrease static electrical discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed as
electrical insulators.
• The power supply cords must include a grounding plug and must be plugged into
grounded electrical outlets.

Chapter 1: Getting Started |13
ReadyNAS 4200 Hardware Manual
General Safety Precautions
Follow these rules to ensure general safety:
• Keep the area around the ReadyNAS 4200 clean and free of clutter.
• The ReadyNAS 4200 weighs approximately 82 pounds when fully loaded. When lifting
the system, two people at either end should lift slowly with their feet spread out to
distribute the weight. Always keep your back straight and lift with your legs.
• Place the chassis top cover and any system components that have been removed away
from the system or on a table so that they will not accidentally be stepped on.
• While working on the system, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled
into a cooling fan.
• Remove any jewelry or metal objects from your body, which are excellent metal
conductors that can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
• Onboard battery: This battery must be replaced only with the same or an equivalent type
recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
DANGER:
There is a danger of explosion if the onboard battery is installed upside
down, which will reverse its polarities.
• Main board replaceable soldered-in fuses: Self-resetting PTC (positive temperature
coefficient) fuses on the main board must be replaced by trained service technicians only.
The new fuse must be the same as or equivalent to the one replaced. Contact technical
support for details and support.

ReadyNAS 4200 Hardware Manual
Electrostatic Discharge (ESD) Precautions
Electrostatic discharge is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is
created to neutralize this difference, which can damage electronic
components and printed circuit boards. The following measures are
generally sufficient to neutralize this difference before contact is made to
protect your equipment from ESD:
• Use a grounded wrist strap designed to prevent static discharge.
• Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready
for use.
• Touch a grounded metal object before removing the board from the antistatic bag.
• Do not let components or PCBs come into contact with your clothing, which might retain a
charge even if you are wearing a wrist strap.
• Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules, or contacts.
• When handling chips or modules, avoid touching their pins.
• Put the main board and peripherals back into their antistatic bags when not in use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and the main
board.
• After accessing the inside of the system, close the system back up and secure it to the
rack unit with the retention screws after ensuring that all connections have been made.
Rack Mount Precautions
Follow these rack mount precautions:
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with
the full weight of the rack resting on them.
• In single-rack installations, stabilizers should be attached to the rack. In multiple-rack
installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component from the rack.
• You should extend only one component at a time; extending two or more simultaneously
might cause the rack to become unstable.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest components on the bottom of the rack first, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS 4200 from
power surges, and voltage spikes and to keep your system operating in case of a power
failure.
• Allow any hot-plug drives and power supply modules to cool before touching them.
• Always keep the rack's front door and all panels and components on the servers closed
when not servicing to maintain proper cooling.
