Esd Precautions - IBM SAN128B-7 Installation, Service And User Manual

ESD precautions

Attention: Many of the field replaceable units (FRUs) are sensitive to electrostatic discharge (ESD),
and can potentially be damaged by improper handling. When working with any FRU, use correct
ESD precautions:
• Attach ground to the indicated area on the chassis
• Wear a wrist grounding strap connected to chassis ground (if the switch is plugged in) or a bench
ground.
Note: For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
• Store ESD-sensitive components in antistatic packaging

CAUTION: Disassembling any part of the power supply and fan assembly
voids the warranty and regulatory certifications. There are no user-
serviceable parts inside the power supply and fan assembly.
CAUTION: Make sure the airflow around the front, and back of the device is
not restricted.
CAUTION: Ensure that the airflow direction of the power supply unit
matches that of the installed fan tray. The power supplies and fan trays
are clearly labeled with either a green arrow with an "E", or an orange arrow
with an "I."
CAUTION: Never leave tools inside the chassis.
CAUTION: To protect the serial port from damage, keep the cover on the
port when not in use.
CAUTION: If you do not install a module or a power supply in a slot, you
must keep the slot filler panel in place. If you run the chassis with an
uncovered slot, the system will overheat.
CAUTION: Do not install the device in an environment where the operating
ambient temperature might exceed 40°C (104°F).
DANGER: For safety reasons, the ESD wrist strap should contain a series 1
megaohm resistor.
CAUTION: Before plugging a cable into any port, be sure to discharge the
voltage stored on the cable by touching the electrical contacts to ground
surface.
CAUTION: Static electricity can damage the chassis and other electronic
devices. To avoid damage, keep static-sensitive devices in their static-
protective packages until you are ready to install them.
