Chapter 2 Preparing for Installation
Site Requirements
• Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohm (Mohm).
Environmental Requirements
Insure adequate spacing between racks using the information in Table 2-1. Keep all of the vents clear of
obstructions, including dust and foreign conductive material, and away from the exhaust ports of other
equipment.
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 2-2 through Table 2-18 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 2-19 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:
• Chassis and fan trays—Table 2-2
• Supervisor engines—Table 2-3
• Policy Feature Cards (PFCs)—Table 2-4
• Distributed Forwarding Cards (DFCs)—Table 2-5
