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:
v Attach ground to the indicated area on the chassis
v 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.
v Store ESD-sensitive components in antistatic packaging
Rack safety
Rack installation
DANGER
Observe the following precautions when working on or around your IT rack system:
v Heavy equipment—personal injury or equipment damage might result if mishandled.
v Always lower the leveling pads on the rack cabinet.
v Always install stabilizer brackets on the rack cabinet.
v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the
bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack
cabinet.
v Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of
rack-mounted devices.
v Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in the rack
cabinet when directed to disconnect power during servicing.
v Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not
plug a power cord from a device installed in one rack cabinet into a power device installed in a different
rack cabinet.
v An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system
or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock.
