Power Connection Guidelines
Ensure all power connection wiring conforms to the rules and regulations in the National Electrical Code
(NEC) as well as local codes.
The chassis has two power trays. Each power tray includes four power modules each. The power tray provides
electrical connections to the chassis backplane. Each power module can be individually plugged in or out
from the tray.
Proper grounding is necessary to avoid damage from lightning and power surges. See the
Supplemental Unit Bonding and Grounding Guidelines, on page 28
for grounding requirements.
Caution
AC-Powered Chassis
AC power modules operate in the input range of 180 VAC to 264 VAC, 47 to 63 Hz (nominal input level of
200 to 240 VAC).
Power redundancy requirements vary based on the system configuration (number and type of line cards, etc.).
AC-powered systems are 2N protected. A minimum of two power supplies are required for redundant operation.
Each of the AC power inputs requires a separate dedicated branch circuit. Note that the circuit breaker and
fuse lockout procedures should follow the rules and regulations in the National Electrical Code (NEC) and
any local codes. For a list of the nominal and acceptable value ranges for source AC power, see
