Site Requirements Chapter 2 Preparing for Installation • If you are planning to install the cable-management brackets on a Cisco 7206 that you are rack-mounting from the front, you must install the cable-management brackets and the rack-mount brackets before you install the chassis in the rack. • Provide an adequate chassis ground (earth) connection for your router chassis. Note We strongly recommend that you provide a chassis ground connection. Refer to Chapter 3, "Installing the Cisco 7206," the "Providing a Chassis Ground Connection for the Router Chassis" section on page 3-12 for instructions. To properly install the Cisco 7206 chassis in a rack, refer to the instructions in Chapter 3, "Installing the Cisco 7206." Site Environment Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are those within which the Cisco 7206 will continue 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.

Chapter 2
Preparing for Installation
Site Requirements
•
If you are planning to install the cable-management brackets on a Cisco 7206 that you are
rack-mounting from the front, you
must
install the cable-management brackets and the rack-mount
brackets
before
you install the chassis in the rack.
•
Provide an adequate chassis ground (earth) connection for your router chassis.
Note
We strongly recommend that you provide a chassis ground connection. Refer to
Chapter 3,
“Installing the Cisco 7206,”
the
“Providing a Chassis Ground Connection for the Router
Chassis” section on page 3-12
for instructions.
To properly install the Cisco 7206 chassis in a rack, refer to the instructions in
Chapter 3, “Installing the
Cisco 7206.”
Site Environment
Table 2-1
lists the operating and nonoperating environmental site requirements. The ranges listed are
those within which the Cisco
7206 will continue 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.
Preventive Site Configuration: Maintaining Normal Operation
Planning a proper location for the Cisco 7206 and the layout of your equipment rack or wiring closet are
essential for successful system operation. Equipment placed too close together or inadequately
ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible
by poor equipment placement can make system maintenance difficult. Following are precautions that can
help avoid problems during installation and ongoing operation.
