Installation Site Requirements

Power Connection Guidelines

The Cisco XR 12404 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.

AC-Powered Routers

A Cisco XR 12404 Router configured with two AC PEMs, are shipped with a three-wire electrical grounding-type plug that will only fit into a grounding-type power outlet. This is a safety feature. The equipment grounding should be in accordance with local and national electrical codes.

At sites where the Cisco XR 12404 Router operates with AC PEMs, observe the following guidelines (Figure 2-3):

•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.

Caution Use the North American plug L6-20 20A only on 240 volt systems.
