The Cisco 12404 Internet router requires an AC PEM or a combination DC PDU
and DC PEM. Site requirements differ depending on the type of power source
voltage. We recommend you follow these precautions and recommendations when
planning power source connections to your router.
Check the power at your site before installation and periodically after
•
installation to ensure that you are receiving clean power from the power
source.
If necessary, install a power conditioner.
•
Install proper grounding, or use the proper grounding receptacle located on
•
the side of the chassis, to avoid damage from lightning and power surges.
At sites where the Cisco 12404 router operates with AC PEMs, observe the
following guidelines (Figure
A power factor corrector (PFC) allows the PEM to accept AC power source
•
voltage from an AC power source operating between 100 to 120 VAC,
15–Amp service in North America; and a range of 185 to 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.
•
Use the North American plug L6-20 20A only on 240 volt systems.
