USER’S MANUAL
• Close the system and (if rack-mounted) secure it to the rack unit with
the retention screws after ensuring that all connections have been made.
4.2 Electrical Precautions
Follow basic electrical safety precautions to protect persons from harm and the
server from damage.
• Lithium Battery
Danger of explosion if battery is incorrectly replaced
o Replace only with the same or equivalent type recommended by
the manufacturer.
o Dispose of batteries according to the manufacturers instructions.
• Be aware of the locations of the power on/off switch on the chassis as
well as the site's emergency power-off switch, disconnection switch, or
electrical outlet.
• Never work on the system with the power cord plugged in. Turning the
computer off is not sufficient to completely power down the system.
The best way to make sure that the system is off is to remove the power
cord.
• When working around exposed electrical circuits, another person
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
to avoid making a complete circuit which will cause electrical shock.
• Metal tools 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.
4.3 ESD Precautions
The following measures generally protect the equipment from ESD:
• Always use a grounded wrist strap designed to prevent static discharge.
• Keep all components and printed circuit boards (PCBs) in their
antistatic bags until ready for use.
