Temperature And Humidity Requirements - Cisco 7200 VXR router User Manual

Site Requirement Guidelines
•
If you are planning to install the cable-management brackets on a Cisco 7200 VXR
router 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
section "Attaching a System Ground Connection" in Chapter 3, "Installing a Cisco 7200
VXR Router," for instructions.
In addition to the preceding guidelines, review the precautions for avoiding
overtemperature conditions in the following section, "Temperature and Humidity
Requirements." To properly install a Cisco 7200 VXR chassis in a rack, see the instructions
in the section "Rack-Mounting a Cisco 7200 VXR Router" in the chapter "Installing a
Cisco 7200 VXR Router."

Temperature and Humidity Requirements

Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges
listed are those within which the Cisco 7200 VXR routers 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.
