○ ○ ○ ○ ○ ○
Note the following when installing internal options:
- Before starting operation, switch off the PC and all connected peripherals and unplug power
cords from respective outlets.
- Immediately after the PC is turned off, internal components and units of the PC are hot.
When installing and removing internal options, turn off the power and allow the PC to cool
down for about 10 minutes before starting operation.
- Do not disassemble the power supply unit (a box-shaped device inside the PC).
- Do not damage or remodel internal cables or units.
- Because internal options are PC boards with exposed soldered sections that may be
damaged by a static electrical charge, discharge any accumulated static electricity before
handling.
- Secure the board by the metal bracket portions or an edge of the PC board such that the
surface of the PC board and the soldered sections are not handled.
- Installation and disassembly of options other than Fujitsu brand products void the warranty.
