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 the chassis ground (if the switch is
plugged in) or a bench ground
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.
