Preventive Site Configuration: Maintaining Normal Operation

Planning a proper location for the Cisco 7204 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.

General Precautions

Follow these general precautions when planning your equipment locations and connections:

Specifications for Operating and Nonoperating Environments
Use the show environment command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and maximum and minimum voltages and creates reports on any occurrences. If
warning messages are displayed, take immediate action to identify the cause and correct the
problem.
We recommend keeping the Cisco 7204 off the floor and out of any area that tends to collect dust.
Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
Ensure that the network processing engine, I/O controller, port adapters, any blank port adapters,
power supplies, and any power supply filler plates are in place and secure. The fans direct cooling
air throughout the chassis interior; a loose component or empty slot can redirect the air flow away
from active components.
