Note These power requirements are for a fully loaded chassis with eight PLIMs. A chassis with six or seven PLIMs uses slightly less power. However, it is a good idea to allocate this much power for each chassis to ensure that enough power is available for future system expansion.

General Power and Grounding Requirements
This section describes the power and grounding requirements you must consider when planning the site facilities for the routing system. In addition, see the “DC Power Requirements” section on page
Note A qualified electrician should review the information in these sections to ensure that the installation site meets these requirements. For larger system configurations, you may want to consult a facilities electrical expert to understand the load that the routing system may put on the facility power plant.
•Installation of the routing system must follow national and local electrical codes:
•In the United States: United States National Fire Protection Association (NFPA) 70 and United States National Electrical Code (NEC).
•In Canada: Canadian Electrical Code, part I, CSA C22.1.
•In other countries: International Electrotechnical Commission (IEC) 60364, parts 1 through 7.
•Two separate and independent AC or DC power sources are needed to provide 2N redundancy for system power. Each power source requires its own circuit breaker.
•Each power source must be providing clean power to the site. If necessary, install a power conditioner.
•The site must provide
•Proper grounding is required at the site to ensure that equipment is not damaged by lightning and power surges. In addition:
•For

•When planning the power for the site, be sure to include the power requirements for any external terminals and test equipment you will use with your system.
