Cabinet
Grounding
To prevent personal injury or electrostatic discharge (ESD), make sure that the
cabinet is correctly grounded. The ground must have the correct low impedance so
that there is no build-up of voltage on any equipment or on any exposed surfaces.
Grounding is especially important to eliminate shock hazards, and to facilitate the
operation of circuit-protective devices.
Consider a low impedance grounding and lightning protection when you plan for and
install an electrical system. Your electrical contractor must meet local code
requirements and national code requirements when installing an electrical system.
NOTE Local codes and local standards might have more stringent requirements.
Always comply with local codes.

Cabinet Power
Distribution
The Model 3040 40U cabinet has two identical AC power distribution units, each of
which has a separate power cords for each side. Depending on your configuration,
each AC power distribution unit supports either North American (USA and Canada)
components or worldwide (excluding USA and Canada) components. Each AC power
distribution unit includes these parts:
 Two cords per side, NEMA L6-30P or IEC 309, for 48A PDUs
 Three cords per side, for 78A PDUs
 Four circuit breakers per side, 15 A each, for 48A PDUs
 Six circuit breakers per side, 15 A each, for 72A PDUs
 Twenty IEC 320 power outlets per side, plus an additional outlet for the optional
fan tray
NOTE For pluggable equipment, the electrical outlet must be installed near the
equipment and must be easily accessible.
