Chapter2 Preparing the Cisco uBR7225VXR Router for Installation
Required Network Information
•Ensure that the network processing engine, cable interface line cards, any blank cable interface line
cards, power supplies, and any power supply filler plates are in place and secure. The fans direct
cooling air throughout the chassis interior; a loose component or empty slot can redirect the airflow
away from active components and cause overheating.

Power Considerations

Follow these precautions and recommendations when planning power connections to the
Cisco uBR7225VXR 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 and appropriate surge suppression if
necessary.
•Install proper grounding to avoid damage from lightning and power surges.
Required Network Information
After you install the chassis, your system administrator must configure the individual and system
interfaces before you connect your system to external networks. Refer to the following documentation
for configuration information.
