User Guide 3. Safety
3.1 Optimizing Location
3.1 Optimizing Location
Failure to recognize the importance of optimally locating your product and failure to protect against
electrostatic discharge (ESD) when handling your product can result in lowered system performance or
system failure.
Do not position the unit in an environment that has extreme high temperatures or extreme low
temperatures. Be aware of the proximity of the unit to heaters, radiators, and air conditioners.
Position the unit so that there is adequate space around it for proper cooling and ventilation. Consult the
product documentation for spacing information.
Keep the unit away from direct strong magnetic fields, excessive dust, and electronic/electrical equipment
that generate electrical noise.
3.2 Safety Warnings and Cautions
To avoid personal injury or property damage, before you begin installing the product, read, observe, and
adhere to all of the following safety instructions and information. The following safety symbols may be used
throughout the documentation and may be marked on the product and/or the product packaging.
CAUTION######Indicates the presence of a hazard that may cause minor personal injury or property damage if
the CAUTION is ignored.
WARNING#####Indicates the presence of a hazard that may result in serious personal injury if the WARNING is
ignored.
#####Indicates potential hazard if indicated information is ignored.
#####Indicates shock hazards that result in serious injury or death if safety instructions are not followed.
#####Indicates do not touch fan blades, may result in injury.
#####Indicates disconnect all power sources before servicing.
3.3 Electrostatic Discharge
##CAUTION
Electrostatic discharge can harm delicate components inside Western Digital products.
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment and
impair electrical circuitry. It occurs when electronic components are improperly handled and can result in
complete or intermittent failures.

User Guide 3. Safety
3.4 Rackmountable Systems
Wear an ESD wrist strap for installation, service and maintenance to prevent damage to components in the
product. Ensure the antistatic wrist strap is attached to a chassis ground (any unpainted metal surface). If
possible, keep one hand on the frame when you install or remove an ESD-sensitive part.
Before moving ESD-sensitive parts place them in ESD static-protective bags until you are ready to install the
part.
3.4 Rackmountable Systems
CAUTION
Always install rack rails and storage enclosure according to 2U24 Flash Storage Platform product
documentation. Follow all cautions, warnings, labels, and instructions provided within the rackmount
instructions.
Reliable grounding of rack-mounted equipment should be maintained.
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
Observe the maximum rated ambient temperature, which is specified in the product documentation.
For safe operation of the equipment, installation of the equipment in a rack should be such that the
amount of air flow is not impeded so that the safe operation of the equipment is not compromised.
3.5 Power Connections
Be aware of the ampere limit on any power supply or extension cables being used. The total ampere rating
being pulled on a circuit by all devices combined should not exceed 80% of the maximum limit for the
circuit.
CAUTION######The power outlet must be easily accessible close to the unit.
#####Always use properly grounded, unmodified electrical outlets and cables. Ensure all outlets and
cables are rated to supply the proper voltage and current.
#####This unit has more than one power supply connection; both power cords must be removed from
the power supplies to completely remove power from the unit. There is no switch or other disconnect
device.
3.6 Power Cords
#####Use only tested and approved power cords to connect to properly grounded power outlets or
insulated sockets of the rack's internal power supply.
If an AC power cord was not provided with your product, purchase one that is approved for use in your
country or region.

User Guide 3. Safety
3.7 Safety and Service
CAUTION######To avoid electrical shock or fire, check the power cord(s) that will be used with the product as
follows:
•The power cord must have an electrical rating that is greater than that of the electrical current rating
marked on the product.
•Do not attempt to modify or use the AC power cord(s) if they are not the exact type required to fit into
the grounded electrical outlets.
•The power supply cord(s) must be plugged into socket-outlet(s) that is / are provided with a suitable
earth ground.
•The power supply cord(s) is / are the main disconnect device to AC power. The socket outlet(s) must
be near the equipment and readily accessible for disconnection.
3.7 Safety and Service
#####All maintenance and service actions appropriate to the end-users are described in the product
documentation. All other servicing should be referred to an Western Digital-authorized service technician.
# #####To avoid shock hazard, turn off power to the unit by unplugging both power cords before
servicing the unit. Use extreme caution around the chassis because potentially harmful voltages are present.
#####When replacing a hot-plug power supply, unplug the power cord to the power supply being
replaced before removing it from the 2U24 Flash Storage Platform.
#####The power supply in this product contains no user-serviceable parts. Do not open the power
supply. Hazardous voltage, current and energy levels are present inside the power supply. Return to
manufacturer for servicing.
# # #####Use caution when accessing part of the product that are labeled as potential shock
hazards, hazardous access to moving parts such as fan blades or caution labels.
