(c) Turning the power on and off
Precautions
• After turning the power off, wait for at least one minute before turning the power on again. If you wait for less
than one minute, the equipment might not operate as specified by the BIOS power settings. (See 5.6 BIOS Setup.)
• Do not turn off power to the equipment or press the reset switch during communication or while a CD, DVD,
HDD, or SSD is being accessed.
Required actions
• When connecting or disconnecting a peripheral, verify that both the equipment and the peripheral have been turned
off. If they have not been turned off, a malfunction or failure might result.
• When turning on the power, turn on the peripherals first, and then turn on the equipment. When turning off the
power, turn off the equipment first, and then turn off the peripherals.
• When you are not using the equipment, turn off the power. If you do not intend to use the equipment for an
extended period of time, unplug the power cord.
• Depending on the material, a rug, lap blanket, or similar material might cause static buildup and consequently
cause a malfunction of the equipment. Use a conductive rug or lap blanket resistant to static buildup.
• If lightning strikes nearby or the AC power supply is not stable, an instantaneous power failure or a brownout
might occur during operation or the screen might black out. In such cases, turn off the power to the equipment, and
then turn the power back on.
(5) Installation environment
Precautions
• When you install a commercially available device in an extension slot, you must meet the specifications of the
required environment for both the commercially available device and this equipment. (See 1.6.1 Environment.)
• When you install an extension board in an extension slot or use a USB device, verify that the power consumption
does not exceed the maximum current rating. (See 5.1(9) Maximum current specifications.)
• To use this equipment without failures for an extended period of time, you must use it by using proper care and in
the proper environment. Do not use the equipment in the following locations. Doing so might reduce the life span
of the equipment or cause a failure in the equipment.
