High-voltage precautions
A high-voltage power supply provides power for the device. Direct or indirect contact
(through damp objects) with a high-voltage power supply (including the main power
in a building) can result in fatal danger.
■When installing the AC power supply, follow standard safety regulations.
Personnel who install the AC power supply must be qualified to perform high
voltage and AC operations.
■Do not wear conductive objects such as a watch, chain, bracelet, or ring during
the operation.
■Switch off the power supply immediately if you find water in the cabinet or if the
rack is damp.
■Make sure that the device is kept away from water when being operated in a
damp environment.
General safety guidelines
High-voltage precautions
10

Improper operation on a high-voltage power supply may result in fire and electric
shock. To connect and route the AC cables through a certain area, you must follow
standard rules and regulations. Personnel must have an up-to-date certificate for
operating high voltage and AC power devices.
You must use insulated tools when operating on high voltage and AC power.
Do not install or remove a power cord or PDU cord when the power is turned on.
Minimal contact between the core of the cord and a conductor can generate an
electric arc or spark, to cause a fire or injury.
■Wrap bare wires of the power cable with insulated tape before connecting the
cable to the power distribution cabinet.
■Before installing or removing the power cord or PDU cord, turn off the power.
■Before connecting the power cord or PDU cord, make sure that the cord and
label conform to the requirements for the installation.
Do not perform operations on high voltage, power supplies and connections, or
other conductive materials during the storms which may produce lightening.
Be sure that all devices are properly grounded to prevent damage or injury during
storms.
See “ESD (Electrostatic Discharge)” on page 11.
ESD (Electrostatic Discharge)
The static discharged by human bodies can damage static-sensitive components
on the boards.
When you install and maintain equipment, observe appropriate static safety
precautions to prevent personnel injuries or device damage.
11General safety guidelines
ESD (Electrostatic Discharge)

Wear ESD-preventive gloves, an ESD-preventive wrist strap, or ESD-preventive
clothes to avoid personnel injury or damage to a device. When a warning indicates
an electrostatic sensitive area, when operating a device you must take
ESD-preventive measures. To prevent the devices from damage, pay attention to
the following during operations:
■Do not touch devices with bare hands because the ESD from the human body
may damage the electrostatically sensitive elements on a board.
■Electronic circuits are prone to damage caused by ESD. When dealing with a
disk, especially a raw disk, wear an ESD-preventive wrist strap, ESD-preventive
gloves, and ESD-preventive suit. Touch only the edge of the disk.
■Use appropriate ESD-preventive bags when picking up, putting down, and
transporting equipment or parts.
To prevent short-circuits, do not leave or drop screws or other metallic parts in the
chassis.
When you install or maintain a device, follow regulations about the use and
placement of tools. You can avoid short-circuits of the devices that are caused by
metallic tools.
See “Combustible gas” on page 12.
Combustible gas
Never place or operate a device in an environment with combustible or explosive
gases, or smoke.
Operations to any electronic devices in the presence of combustible gases cause
an extreme danger.
See “Batteries” on page 12.
Batteries
Follow the safety precautions for operating lithium (Li-ion) batteries against personnel
and device damage during installation and maintenance of Veritas products.
Be sure that you use correct replacement batteries. Otherwise, an explosion may
occur.
■Only use batteries of the same or a similar model as recommended by the
vendor.
■Deal with the waste batteries according to standard instructions.
■Do not put a lithium battery into a fire.
General safety guidelines
Combustible gas

See “Lasers” on page 13.
Lasers
When you install and maintain equipment, observe standard laser safety precautions
to prevent personnel injury or device damage.
The laser that is emitted by the optical interface board is an invisible infrared ray.
This laser can cause permanent damage to eyes.
During device maintenance, direct eye exposure to the laser light must be avoided.
To prevent device damage when you operate the device, take the following
precautions:
■Cap any unused optical interfaces and the optical connectors of unused tail
fibers.
■Use caps when you remove the optical tail fiber that connects to an optical port
that is in use. Cover the optical port on the device and the optical connector of
the tail fiber with dust-proof caps.
■Use an attenuator when you perform a hardware loopback test on the optical
connector with the tail optical fiber. The attenuator protects the optical transceiver
from the received optical power.
■Disconnect the optical tail fiber between the peer device and the local device
when you use the Optical Time Domain Effect Reflectometer (OTDR).
Disconnecting the fiber protects the optical transceiver from the optical power
source.
■Do not remove or insert the optical transceiver that connects to the optical fiber
without proper safety procedures.
See “Optical fibers” on page 13.
Optical fibers
The laser beams of the optical interface board or inside the optical fibre may cause
damage to the eyes. Do not expose your eyes to the laser beams.
The safe use of optical fibers ensures proper running of the device and avoids
personnel injuries and device damage.
The fibre connectors and optical fibre interfaces of a laser must be cleaned with
the special tools and the materials that are listed:
■The special cleaning solvent, isoamylol,is preferred. Propyl alcohol is the next
best solvent. Other alcohols and formalin are forbidden.
13General safety guidelines
Lasers

■Non-woven lens tissue
■Special compressed gas
■Cotton stick (medical cotton or long fibre cotton)
■Special magnifier for optical connectors
When replacing a fibre, cap the connector of a fibre that is not used. Avoid bending
or wrapping fibers around narrow or sharp objects.
See “Precautions when troubleshooting with the power turned on ” on page 17.

from falling over. The rack can fall when one or more units are extended in front
2
Chapter

of the rack on the slides. You must also consider the weight of any other device
that is installed in the rack. A crush hazard exists and can cause serious injury
should the rack tilt forward.
■Check temperature
When the devices are installed in an equipment rack, the temperature must be
in the range of 5C (41F) to 40C (104F). Extreme fluctuations in temperature can
cause a variety of problems for the appliance.
■Check ventilation
The equipment rack must provide sufficient airflow to the front of the devices to
maintain proper cooling. The rack must also include ventilation sufficient to
exhaust a maximum of 2550 BTUs (British Thermal Units)per hour for the
appliance. The rack that is selected and the ventilation that is provided must be
suitable to the environment in which the equipment is used.
■Main AC power must be accessible
The AC power cord(s) is considered the main disconnect for the device and
must be readily accessible when installed. If the individual power cord(s) are
not readily accessible for disconnection, you must install an AC power disconnect
for the entire rack unit. This main disconnect must be readily accessible, and it
must be labeled as controlling power to the entire rack unit.
■Grounding the rack installation
To avoid the potential for an electrical shock hazard, you must include a third
wire safety ground conductor with the rack installation. The rack itself must have
a proper grounding when device power cords are plugged into the AC outlet of
the rack. The devices must be plugged into a properly grounded AC outlet.
■Overcurrent protection
The power supplies contain internal overcurrent protection. If power draw
increases, the power supplies shutdown. Hardware monitoring utilities such as
the NetBackup Appliance Web Console show alerts that indicate problems in
the power supply.
The following values are based on power supply ratings of the various devices.
