indicates an electrostatic sensitive area. When performing operations at this area
take strict measures, such as wearing an ESD preventive wrist strap, ESD preventive gloves,
and ESD preventive clothes, to avoid personal injuries or device damages caused by static
electricity.
To protect the devices, note the following:
Do not touch the exposed device modules with bare hands because the static electricity
of the human body may damage the electrostatic sensitive elements on the circuit boards.
The ESD preventive wrist strap can prevent devices from being damaged by static
electricity from the human body.
To avoid personal injuries or device damage caused by static electricity, you need to
wear ESD gloves or an ESD preventive wrist strap before installation or replacement.
When you carry and move parts, a dedicated ESD preventive bag is required.
1.3 Laser Safety
When you install and maintain the device, you must follow the laser safety precautions to
ensure the safety of the human body and the device.
Laser safety precautions include two aspects:
Human body injury
Device damage

1 Safety Precautions
NetBackup 5020

Symantec Corporation
Issue 01 (2010-12-10)
Human Body Injury
The laser sent by the optical interface board is an invisible infrared ray. While maintaining the
device, protect your eyes from the laser; otherwise, the laser may cause permanent injury to
your eyes.
Device Damage
To prevent damage to the device, observe the following:
If the optical interface on the device or on the patch cord is not in use, cover the optical
interface with a dust-proof cap.
When you need to remove the patch cord connected to the optical interface in use, cover
the optical interface and the patch cord connector with dust-proof caps.
When you perform the loopback test on the optical interface with the patch cord, you
must use an attenuator to protect the optical transceiver from the received optical power.
When you use the optical time domain reflectometer (OTDR), disconnect the patch cord
between the peer device and the local device to protect the optical transceiver from the
optical power.
Do not remove or insert the optical transceiver that connects to fiber during operation.
1.4 Using Optical Fiber
You should use optical fibers properly to ensure the normal running of the device; otherwise,
bodily injury or device damage may be caused.
The laser beam of the optical interface board or inside the optical fiber may injure your eyes!
When you install and maintain the optical interface board and the optical fiber, keep your eyes
away from, and never stare into the optical interface or the optical fiber connector.
Cleaning Optical Fiber Connectors and Optical Interfaces
The optical fiber connectors and the optical interfaces of the laser must be cleaned with
special cleaning tools and materials listed as follows:
Special cleaning solvent. Isoamylol is preferred, propyl alcohol is the acceptable, alcohol
is not recommended and formalin is forbidden
Non-woven lens tissue.
Special compressed gas
Cotton swabs (medical cotton swab or other long-staple cotton)

Special cleaning roll (used with Isoamylol)
Special magnifier for optical connectors
Replacing Optical Fibers
When replacing the optical fiber, cover the optical connector that is not in use with dust-proof
caps.
1.5 Short-Circuit Protection
When you install or maintain the device, use tools according to the regulations to avoid short
circuit as a result of metallic tools.
Do not place tools, such as the screwdriver on the air intake board of the enclosure; otherwise,
short circuit may occur.
Avoid dropping screw into the sub-rack or the device; otherwise, short circuit may occur.
1.6 Electrical Safety
When you install and maintain the equipment, follow the electrical safety precautions to avoid
device damage or bodily injury.
Power On and Power Off
Before you check the installation and cable connections, ensure that the entire storage system
is powered off. If there is improper connection, you or the device could be damaged during
the check.
If you need to perform hot-line operations and the cables that you touch are power cables, you
must take off the ESD-preventive wrist strap.
During power-on, do not insert or remove the cable. Otherwise, data might be lost.
After switching off the power supply, wait at least one minute before switching on the
power supply again.

Do not switch off or on the power before disks stop running. Otherwise, disks may be
damaged and data could be lost.
Troubleshooting
Do not touch the connectors of electrical wires and communication cables, as the electricity
inside the electrical wires and communication cables could result in electrical shock.
When you operate a device in the ESD-sensitive area, you must take ESD-preventive
measures, such as wearing an ESD-preventive wrist strap, ESD-preventive clothes , and
ESD-preventive gloves.
Monitor the following items during troubleshooting:
Do not troubleshoot a device during an electrical storm.
Check that the power cables are intact and effective grounding measures are taken.
Keep the troubleshooting area clean and dry.
