Basic electrical safety precautions should be followed to protect yourself from harm
and the 1011S-MR2 from damage:
Be aware of the locations of the power on/off switch on the chassis as well as
the room's emergency power-off switch, disconnection switch or electrical
outlet. If an electrical accident occurs, you can then quickly remove power
from the system.
Do not work alone when working with high voltage components.
Power should always be disconnected from the system when removing or
installing main system components, such as the motherboard, memory
modules and fl oppy drive. When disconnecting power, you should fi rst power
down the system with the operating system fi rst and then unplug the power
cords of all the power supply units in the system.
When working around exposed electrical circuits, another person who is
familiar with the power-off controls should be nearby to switch off the power
if necessary.
Use only one hand when working with powered-on electrical equipment. This
is to avoid making a complete circuit, which will cause electrical shock.
Use extreme caution when using metal tools, which can easily damage any
electrical components or circuit boards they come into contact with.
Do not use mats designed to decrease static electrical discharge as protection
from electrical shock. Instead, use rubber mats that have been specifi cally
designed as electrical insulators.
The power supply power cords must include a grounding plug and must be
plugged into grounded electrical outlets.
