Basic Chassis Power Recommendations
The Cisco CRS-1 Carrier Routing System 4-Slot Line Card Chassis can be configured with either an
AC-input power subsystem or a DC-input power subsystem. Site power requirements differ depending
on the source voltage used. Follow these precautions and recommendations when planning power
connections to the router:
• Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner, if necessary.
• Install proper grounding to avoid damage from lightning and power surges.
