Chapter 2 Preparing for Installation
Site Requirements
Temperature and Humidity Requirements
Table 2-1
lists the operating and nonoperating environmental site requirements. The ranges listed are
those within which the Cisco uBR10012 router continues to operate; however, a measurement that is
approaching the minimum or maximum of a range indicates a potential problem. You can maintain
normal operation by anticipating and correcting environmental anomalies before they approach a
maximum operating range.
Power Guidelines
Caution
The Cisco uBR10012 router installation must comply with all applicable codes and is approved for use
only with copper conductors. The ground bond fastening hardware should be of compatible material and
preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system should be made with
a minimum of a 6-AWG, copper ground conductor.
Follow these precautions and recommendations when planning power connections to the
Cisco uBR10012 router:
•
Ensure that you are using proper cables and have circuit breakers installed.
•
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 to avoid damage from lightning and power surges.
•
Use a 6-AWG, copper ground conductor (minimum requirement) when attaching the chassis ground
to a central office or other interior ground system. An insulation rating of 167° Fahrenheit (75°
Celsius) is required for the 6-AWG wire for 3000 W of power.
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.
Statement 1045
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
