Safety information
To avoid bodily injury or damage to the server, read the following information carefully before you
operate the server. In practice, the safety information includes but is not limited to what are
mentioned in this document.
General operating safety
To avoid bodily injury or damage to the server, follow these guidelines when you operate the server:
•
Only H3C authorized or professional server engineers are allowed to install, service, repair,
operate, or upgrade the server.
•
Place the server on a clean, stable table or floor for servicing.
•
Make sure all cables are correctly connected before you power on the server.
•
Keep the server clean and dust-free, and do not place the device in a wet environment or let
liquid flow into the device.
•
Make sure that you move or place the server evenly and slowly.
•
To avoid being burnt, allow the server and its internal modules to cool before touching them.
Electrical safety
To avoid bodily injury or damage to the server, follow these guidelines:
•
Verify whether the operation area has potential risks carefully, such as an ungrounded chassis,
unreliable grounding, or wet floor.
•
Make sure that you disable the power supply before you perform actions in power-off state.
•
Power off the server when installing or removing any components that are not hot swappable.
ESD prevention
Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the
system board and electrostatic-sensitive components.
Preventing electrostatic discharge
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the server with the components in antistatic bags.
•
Keep the electrostatic-sensitive components in separate antistatic bags until they arrive at an
ESD-protected area.
•
Place the components on a grounded surface before removing them from their antistatic bags.
•
Avoid touching pins, leads, or circuitry.
•
You must take ESD preventions before touching the electrostatic-sensitive components.
Grounding methods to prevent electrostatic discharge
The following are grounding methods that you can use to prevent electrostatic discharge:
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Take adequate personal grounding measures, including wearing antistatic clothing and static
dissipative shoes.
•
Use conductive field service tools.
