Maintenance
CAUTION
1. Be sure to turn OFF the power mounting or removing the module, terminal block, and
cable. Failing to do so can cause electric shock, malfunction, and/or failure.
2. Carry out daily check, periodical check, and cleaning to keep the system in normal
condition.
3. If your DN211 does not operate normally, refer to "7. Troubleshooting" to identify the
cause of the trouble.
Contact a Toshiba's branch office (or dealer) or service agency for returning your
DN211 for repair when failed. Operation and safety of your DN211 can be
guaranteed only when repaired by Toshiba or a Toshiba's authorized service
agency.
4. Neither try to disassemble nor modify the hardware of the module. Similarly, don't
modify the software by any means. Failing to do so could cause fire, electric shock,
and/or injury due to failure or malfunctioning.
5. Make sure you are safe when measuring the voltage on the connector of the module.
Failing to do so could cause electric shock.
6. Stop the network and turn OFF the T2/T2E/T2N side power before replacing the
module.
Failing to do so could cause electric shock, malfunction, and/or failure.
7. Don't use your DN211 in abnormal condition such as smoking or nasty smelling.
Failing to do so could cause fire, electric shock, and/or failure.
If such an abnormal condition happens, turn OFF all the power supplies immediately
and contact a Toshiba branch office (or dealer) or authorized service agency.
Since it is very dangerous, don't engage yourself in modifying or repairing your
DN211 by any means.
