Chapter 2 Power and Cooling General Power and Grounding Requirements An AC-powered chassis requires 8,750 watts of AC input power. 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.

Chapter 2 Power and Cooling DC Power Requirements DC Power Requirements A DC-powered line card chassis contains two DC-input power distribution units (PDUs) and two DC power entry modules (PEMs). Each DC PDU is connected to three DC power inputs and contains a single 7500-watt DC PEM that is field replaceable. Input DC power enters the PDU and is passed to the PEM, which provides power to the components in the chassis. Each PEM has its own circuit breaker. In addition to the requireme

Chapter 2 Power and Cooling DC Power Requirements Each DC input power cable is terminated at the PDU by a cable lug. The cable lugs must be dual-hole, and have a 45-degree angle tongue. They must be able to fit over 1/4-inch terminal studs at 0.625-inch (15.88-mm) centers. For example, you could terminate a 2-AWG power cable with a cable lug, such as Panduit part number LCC2-14AWH-Q (Cisco part number 32-0677-01) or equivalent (see Figure 2-1). Note To avoid hazardous conditions, all

Chapter 2 Power and Cooling AC Power Requirements Caution Although reverse polarity should not damage the DC power system, you should correct a reverse polarity condition immediately. AC Power Requirements An AC-powered line card chassis contains two AC power distribution units (PDUs) and two AC rectifier modules. Each AC PDU is connected to an input AC power source and holds a single 7500-watt AC rectifier. Input AC power enters the PDU and is passed to the rectifier. Here, the input
