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 AC power source operating between 100–120VAC, 15–Amp
service in North America; and a range of 185–264 VAC, 10–Amp service, in
an international environment.
•All AC PEM power cords measure 14 feet (4.3 meters).
•Provide a dedicated power source for each PEM installed in the router.
•Install an uninterruptable power source where possible.
