The Cisco 7505 router is a part of the Cisco 7500 series, and is a five-slot multiprotocol, multimedia router/bridge. Network interfaces reside on interface processors, which provide a direct connection between the Cisco Extended Bus (CyBus) and external networks.
The Cisco 7505 has five slots: four interface processor slots (0 through 3) and one slot for the Route Switch Processor (RSP1). The Cisco 7505 uses a single power supply, with two models available: DC input or AC input.
Figure 1-1 shows the interface-processor end of the Cisco 7505 (with an AC-input power supply installed).

Figure 1-2 shows the chassis fan array and airflow in the Cisco 7505.
Figure 1-2 Cisco 7505 Fan Array and Airflow
Six individual axial fans draw cooling air through the chassis interior to maintain an acceptable temperature for the internal components. The fans draw air in through the inlet vents on the side of the chassis opposite the fans, across the processor modules and other internal components, and through the exhaust vents adjacent to the fans.
The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis. A temperature sensor on the RSP1 monitors the internal air temperature. The power supply has two fans for cooling.
For complete information on fan operation and environmental considerations related to fan speed, refer to the Cisco 7505 Hardware Installation and Maintenance publication. For information on ordering printed documentation or Cisco Connection Documentation CD-ROM, refer to the section "If You Need More Configuration Information," in the chapter "Performing a Basic Configuration of the Cisco 7505."
