CH A P T E R 1 Cisco CRS-1 Carrier Routing System This site planning guide describes how to plan and prepare your site facilities for the installation of a Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis (also referred to in this document as the “Cisco CRS-1 8-slot line card chassis”). The guide provides a brief description of the chassis and its components, and basic site facilities requirements.
Chapter 1 Cisco CRS-1 Carrier Routing System The Cisco CRS-1 8-Slot Line Card Chassis The Cisco CRS-1 8-Slot Line Card Chassis The Cisco CRS-1 8-slot line card chassis is the main component of the Cisco CRS-1. The chassis is a mechanical enclosure that contains a chassis midplane. The midplane holds the system modular services cards (MSCs), their associated physical layer interface modules (PLIMs), and switch fabric cards. The chassis is mounted in a 19-inch equipment rack.

CH A P T E R 2 Power and Cooling This chapter describes the Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis power and cooling systems. It also provides the power and grounding and cooling requirements for the installation site to help you plan the site facilities for the system. The Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis System Description provides detailed information about these components.
Chapter 2 Power and Cooling General Power and Grounding Requirements • Note An AC-powered chassis requires 8,750 watts of AC input power. 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.
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).

Figure 2-3 DC PDU Power Cable Connections 129533 1 1 Each set of cables (RTN and –48V/–60V) is a single VDC input. Note When wiring the PDU, be sure to attach the ground wire first (shown above on the far left side of PDU).
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.

In addition, the next section “AC PDU Wiring” describes the 3-phase wiring for AC Delta and Wye configurations.

As shown, input AC power is routed to three internal 2.5-kW power modules in the rectifier, where it is converted into DC power (nominal 54.
Chapter 2 Power and Cooling Supplemental Bonding and Grounding Supplemental Bonding and Grounding The 8-slot line card chassis has a safety earth ground connection as part of the power cabling to the PDUs. The chassis also has supplemental bonding and grounding points (two threaded ground inserts) that you can use to connect the router to the central office ground system or interior equipment grounding system.
Chapter 2 Power and Cooling Chassis Airflow Chassis Airflow The Cisco CRS-1 8-slot line card chassis has two fan trays, with three fans each, that cool the chassis card cages. Cool air flows in at the bottom front of the chassis and flows through the chassis card cages and through the fans in the fan trays before being exhausted through the bottom rear of the chassis (see Figure 2-9).
Chapter 2 Power and Cooling Facility Cooling Requirements Heat dissipation and external cooling requirements for the 8-slot line card chassis are as follows: • Heat dissipation: 27,350 BTUs per hour • External cooling requirements: 2.3 tons To ensure that the site provides the proper air circulation for the system: • Make certain that the site is as dust free as possible. Dusty environments can clog the air filter or power supply intake vents, reducing the cooling airflow through the system.

CH A P T E R 4 Site Planning Considerations This chapter describes the general considerations to address while planning for the installation of the Cisco CRS-1 8-Slot Line Card Chassis. It does not repeat the specifications in Chapter 3, but you should keep those specifications in mind as you plan for your system.
Chapter 4 Site Planning Considerations Tools Required for Installation • At least 48 inches (122 cm) of clearance exists between rows of equipment racks. This space is needed to access components in the chassis. Additional clearance may be necessary for installation. • Enough room exists for the system console terminal, and that the console cable is long enough to reach the routing system from the terminal.
Chapter 4 Site Planning Considerations Equipment Rack Considerations • Tape measure (optional) Equipment Rack Considerations A fully loaded Cisco CRS-1 8-slot line card chassis weighs 650 lb (294.8 kg). The chassis is mounted in a four-post rack. (See Figure 4-1.) To ensure safe installation and operation of the routing system, you must install the chassis in a four-post equipment rack that meets the specifications described in the “Equipment Rack Specifications” section on page 3-2.
Chapter 4 Site Planning Considerations Aisle Spacing and Maintenance Access Floor Plan Note We recommend that you use a scissor lift or similar lifting device to position the chassis in the rack and to hold the chassis in place while you bolt it to the rack. A forklift is not recommended for this purpose.

Table 4-1 Route Processor Cables RP Port Required Cable Type Ethernet management Shielded twisted-pair (STP) cable (Category 5 or better).
Chapter 4 Site Planning Considerations Noise Control Noise Control A routing system can generate large amounts of fan noise. The 8-slot line card chassis has some built-in noise reduction, such as fan speed control. If the routing system is installed in an environment where excessive noise could be harmful to personnel, some other noise reduction options could be attempted. Passive noise reduction could include the installation of foam panels to insulate the surrounding area from the noise.
