Safety Precautions (continued)
• Mounting in the base unit
CAUTION
1. The Ethernet Port is built-in the PU235N/245N. Do not remove the Ethernet Port from a
PU235N/245N.
2. The PU235N/245N itself should only be mounted or removed when all power is turned off. Similarly,
connections to the terminal block should only be made or removed when all power is turned off. Not
observing this precaution could result in electrical shocks, malfunctions, or damage to the
PU235N/245N or other equipment.
3. Do not allow foreign objects such as wire shreds to get into the PU235N/245N. This could result in
fire, breakdown, or malfunction.
4. Verify that connectors, cables, and the mounting of the PU235N/245N itself in the base unit are all
secured and that there is no play, missing screws, or disconnections in any of these parts.
If any of these parts is inadequately secured, breakdown or malfunction could occur as the result of
vibration.
3.3 Mounting in the Base Unit
• Connecting to the network
CAUTION
1. Do not connect or disconnect cables when either the T2N or HUB power supply is turned on. This
can damage the PU235N/245N or cause it to malfunction.
2. When installing a 10BASE-T network, the cabling must be laid with adequate safety precautions and
in accordance with all applicable standards. Installation and wiring should be performed by a
qualified professional.
See the ISO/IEC8802-3 standard for installation environment standards.
