Chapter 1 Product Overview
Chassis
Power
Because a Cisco 12006 or Cisco 12406 Router can be configured with either an AC-input power system or a DC-input power system, the power module bays will accept either AC-input power supply modules or DC-input PEMs. For more information about the power subsystems, see the “Power Subsystems” section on page 1-37.
Caution To ensure that the chassis configuration complies with the required power budgets, use the on-line power calculator. Failure to properly verify the configuration may result in an unpredictable state if one of the power units fails. Contact your local sales representative for assistance.
Cooling
Cisco 12006 and Cisco 12406 routers are equipped with a blower module to distribute air within the chassis. The blower module is a removable module located on the rear of the chassis. (See Figure 1-2.) For more information about the blower module, see the “Blower Module” section on page 1-47.
