Note This document describes the Cisco 7609 Internet Router (OSR-7609) and not the Cisco 7609 Internet Router (CISCO7609).
This chapter describes how to prepare your site for Cisco 7609 Internet Router (OSR-7609) installation and contains these sections:
For detailed information about module cabling requirements, see Appendix B, "Connector and Cable Specifications."
Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.
This section provides site power requirements for the Cisco 7609 Internet Router. You should verify the site power prior to installing the switch. Power requirements vary for each switch; ensure that you verify the site power for the type of switch you are installing.
For EMI recommendations, refer to the Site Preparation and Safety Guide.
Insure adequate spacing between racks using the information in Table 2-1. Keep all of the vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.

Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. The power and heat associated with a Cisco 7609 Internet Router varies based upon these considerations:
•Power supply type
•Module types and quantities
•Average traffic levels
Unless otherwise noted, the information in Table 2-2 and Table 2-3 assumes worst-case conditions (with GBICs and port adapters installed, if applicable). Typical numbers are approximately 30 percent below the numbers listed here. See Table 2-4 for a sample calculation of a switch configuration.

Table 2-4 provides a sample calculation of power and heat dissipation for the following switch configuration:
•Cisco 7609 Internet Router chassis (including AC-input power supplies)
•Two WS-X6K-S2U-MSFC2 supervisor engines
•One Switch Fabric Module
•Two 4-port OC-12 POS modules
•Two 8-port OC-3 POS modules
Follow these requirements when preparing your site for the switch installation:
•The redundant power option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.
•In systems configured with the redundant power option, connect each of the two power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.
•To prevent a loss of input power, be sure the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
•In some systems, you might use an uninterruptible power supply (UPS) to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco 7609 Internet Router, which can have substantial current draw fluctuations due to bursty data traffic patterns.
Use the information in Table 2-2 to estimate the power requirements and heat dissipation of a Cisco 7609 Internet Router based on a given configuration of the switch. Table 2-4 provides a sample calculation. Determining power requirements might be useful for planning the power distribution system needed to support the switch.
This section provides the guidelines for connecting the Cisco 7609 Internet Router AC and DC power supplies to the site power source.
Basic guidelines include the following:
•Each chassis power supply should have its own dedicated branch circuit.
•For North America, the circuit breaker should be rated 20A for the 2500W power supply and 30A for the 4000W power supply. For everywhere else, the circuit breaker should be sized according to the power supply input rating and local or national code requirements.
•If you are using a 200/240 VAC power source in North America, the circuit must be protected by a dedicated two-pole circuit breaker.
•The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily accessible.
•The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.
Two types of AC-input power supplies are available:
•2500W—Figure 2-1 shows the different styles of 2500W AC-input power cord plugs that are available for North America or various international locales. Figure 2-1 also shows the appliance coupler that is attached to the other end of the 2500W power supply power cord. Table 2-5 lists the AC-input power cord options and Cisco product numbers.
•4000W—Figure 2-2 shows the two different styles of AC-input power cord plugs that are available for North America and international locales. Unlike the other power supplies, the 4000W power supply power cord is hardwired to the power supply and cannot be removed.
Figure 2-1 AC Power Cord Plugs and Appliance Coupler for the 2500W Power Supply
Figure 2-2 AC Power Cord Connectors for the 4000W Power Supply
Basic guidelines include the following:
•Each chassis power supply should have its own dedicated input power source.
•The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be sized according to the power supply input rating and local or national code requirements.
•The circuit breaker is considered the disconnect device and should be easily accessible.
•The power supply ground should connect to protective earth ground even though the system ground connection is provided.
•The DC return is to remain isolated from the system frame and chassis (DC-I).
Table 2-6 lists the site planning activities that you should perform prior to installing the Cisco 7609 Internet Router. Completing each activity helps ensure a successful switch installation.
