4-1
Basic electrical safety precautions should be followed to protect yourself from harm
and the A+ SERVER 2022TG-HTRF/HIBQRF 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 in-
stalling main system components, such as the serverboard, memory modules
and fl oppy drive. When disconnecting power, you should fi rst power down the
operating system fi rst and then unplug the power cords. The unit has more
than one power supply cord. Disconnect two power supply cords before
servicing to avoid electrical shock.
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 neces-
sary.
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.
