Safety information
To avoid personal injury or damage to the device, read the following information carefully before you
operate the device. Safety precautions in actual operation include but are not limited to safety
information mentioned in this document.
General operating safety
•
Only H3C authorized or professional engineers are allowed to operate the device.
•
Keep the device clean and dust-free. Do not place it in a humid place or allow liquids to enter it.
•
Before powering on the device, ensure that the blade enclosure is securely grounded.
•
To maintain sufficient heat dissipation, use filler panels on idle slots.
Electrical safety
•
Carefully check any potential hazards in the work area, for example, whether the ground is wet
and whether the blade enclosure is grounded or reliably grounded.
•
Do not work alone when performing live-line maintenance.
•
Do not touch the power supply directly or indirectly through conductive objects to prevent
electric shock.
Safety precautions
•
When maintaining the device, place the device on a clean, stable table or floor.
•
To avoid personal injury from hot surfaces or internal components, allow the device and its
internal components to cool before touching them.
•
When using tools to maintain the device, follow the correct operation methods to avoid damage
to the personnel or device.
•
When connecting, testing or replacing optical fibers, do not look directly into the optical fiber
outlet to prevent the laser beam from hurting your eyes.
•
Gently and slowly transport or place the device with force evenly distributed.
ESD prevention
Preventing electrostatic discharge
Electrostatic charges that build up on people and conductors damage or shorten the lifespan of the
main board and electrostatic-sensitive components.
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the device in an ESD bag.
•
Place the device on a grounded table before taking it out of the ESD bag.
•
Avoid touching pins or circuitry of the device without taking any ESD prevention measures.
