Installation Guidelines
This section contains information about power and cabling guidelines, workbench or tabletop installation, and rack-mount
installation guidelines.
Power Guidelines
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 if necessary.
• Provide proper grounding. A grounding lug mount is provided on the rear of the chassis.
•
Make sure that the frame ground is tied to a single building ground.
•
Use a 6-AWG, copper ground conductor (minimum requirement) when attaching the chassis ground to a headend or other
interior ground system.
Cabling Guidelines
When planning the location of a new system, keep in mind signal type, signal speed, and transmission medium, as well as
distance limitations for signaling, EMI, and connector compatibility. Use this information as a guideline in planning your
network connections before installing the Cisco uBR7225VXR router.
Ethernet and Fast Ethernet Connections
