Proper grounding is necessary to avoid damage from lightning and power surges. See
Unit Bonding and Grounding Guidelines, on page 44
for grounding requirements.
Caution
AC-Powered Routers
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). Refer the below tables for the minimum required AC service for version 1 and version 2
power modules.
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.
Refer to the Cisco ASR 9000 Power Calculator at the following URL to determine actual redundancy
requirements for any given configuration:
http://tools.cisco.com/cpc/launch.jsp.
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

This table lists the AC input power cord options, specifications, and Cisco product numbers for the AC input
version 1 power supply modules. lists the AC input power cord options, specifications, and Cisco product
numbers for the AC input version 2 power and version 3 supply modules.
Before connecting AC input power cords to the power system, make sure that the power cords are not energized.
