Appendix A Technical Specifications Product Architecture Warning Exhaust from other equipment vented directly into the Cisco 12404 Internet router air inlet may cause an over-heat condition. Install the router so that it is protected from a direct flow of hot air from other equipment. AC-Powered Routers At sites where the Cisco 12404 router operates with AC PEMs, observe the following guidelines. A power factor corrector (PFC) allows the PEM to accept AC power source voltage from an
