Electrical Safety Precautions
•
Basic electrical safety precautions should be followed to protect you from harm
and the Viglen CX135 Server 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 the CD-ROM and floppy drives. When disconnecting power, you should first
power down the system with the operating system 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 electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed
as electrical insulators.
•
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
•
Motherboard Battery: CAUTION - There is a danger of explosion if the onboard
battery is installed upside down, which will reverse its polarities. On the VIG705P,
the positive side should be facing up. This battery must be replaced only with the
same or an equivalent type recommended by the manufacturer. Dispose of used
batteries according to the manufacturer's instructions.
