Abnormal heat, smoke, abnormal noise, or abnormal smell
Should you find anything abnormal occurring, turn off the power and unplug
all the power cables of the equipment (maximum of 2) from the electrical
outlets.
Do not repair, remodel or disassemble
Do not attempt to repair, remodel or disassemble the equipment on your
own, except for performing expansion work in accordance with the
instructions in this manual. Work performed by unqualified persons can lead
to an electric shock, fire, or burns. Especially it is hazardous if you touch
areas inside the high-voltage power unit.
Removal of the cover or bracket
Do not remove the cover or bracket. It can result in an electric shock, burns
or equipment failure.
High temperature at a power supply
When a power supply is in operation, the cover and handle get hot. Be careful
when replacing a failed module. You can get burned.
Adding and replacing parts
The cover and internal parts are hot immediately after the power is turned
off. You must wait for about 10 minutes before adding or removing internal
parts unless otherwise specified in this manual. If not, the hot equipment
causes you to get burned.
Installing internal component and connecting peripherals
•
When you remove a cover for removing and installing components or
connect peripherals, disconnect all the AC cables from electrical outlets
and disconnect all signal cables from the system unit unless otherwise
specified.
Otherwise, you get injury or electric shock. Also malfunction of the system
unit might result.
•
Use peripherals, internal components, signal cables, and AC cables that
the manual describes as supported.
Otherwise, compatibility issues might occur and malfunction of the
peripherals, internal component, and the system unit. Also burn, smoke,
or fire might occur.
