Cisco 7600 Series Router Installation Guide
OL-4503-26
Chapter 2 Preparing for Installation
Site Requirements
Heat dissipation is an important consideration for sizing the air-conditioning requirements for an
installation. The power and heat associated with a Cisco 7600 series router varies based upon these
considerations:
•
Power supply type
•
Module types and quantities
•
Average traffic levels
Unless otherwise noted, the information in
Table 2-3
through
Table 2-19
assumes worst-case conditions
(with GBICs and port adapters installed, if applicable), so typical numbers are approximately 30 percent
below the numbers listed here. See
Table 2-20
for a sample calculation of a router configuration.
This section provides the power and heat numbers for the Cisco 7600 series chassis and modules. The
following power requirements and heat dissipation tables are provided:
•
