Safety Precautions (continued)
• Basic points in laying out a network
CAUTION
1. When laying network cable, take adequate safety measures and perform all operations in
accordance with the relevant standards. See the ISO/IEC8802-3 standard for details on laying
networks.
2. We strongly recommend hiring a qualified contractor who has specialized knowledge about safety
precautions and standards.
3. Avoid installing 10BASE5, 10BASE2 or 10BASE-T networks in environments that have high noise
levels. If it is necessary to install network cables in an environment subject to noise (electromagnetic
interference), use the noise reduction measures described elsewhere in this document.
9.2 Network Wiring
• Maintenance
CAUTION
1. Always turn off the power before attaching or removing modules or cables. Electrical shock,
malfunctions, and breakdowns are possible if these operations are performed with the power on.
2. To keep the system operating normally at all times and to prevent trouble in advance, perform daily
inspections, periodic inspections, and cleaning.
3. Refer to the section on error recovery in this document if the Ethernet Port does not operate
correctly.
Contact your local Toshiba dealer or service representative if a breakdown occurs, and request that
the module be repaired or returned to Toshiba.
Operation and safety cannot be guaranteed if service is performed by anyone other than an
authorized Toshiba service representative.
4. Do not disassemble or modify the module hardware, and do not modify the module software.
Breakdowns or malfunctions may lead to fire, electrical shock, or injury.
5. Do not continue to use the module if it emits smoke or unusual odors, or if it is in an abnormal state
of any type.
Using the module in an abnormal state can lead to malfunctions, breakdowns, and electrical shock.
In such cases, immediately turn of all power and contact your local Toshiba dealer or service
representative.
Customers should never attempt repairs or modifications to this equipment themselves: repair and
modification operations are extremely dangerous.
