Site Requirement Guidelines
Warning
where access can only be gained by service personnel through the use of a special tool, lock and key,
or other means of security, and is controlled by the authority responsible for the location.
The environmental monitoring functionality in the router protects the system and components from
potential damage from overvoltage and overtemperature conditions. To ensure normal operation and
avoid unnecessary maintenance, plan your site configuration and prepare your site before
installation. After installation, make sure the site maintains an ambient temperature of 32°F through
104°F (0°C through 40°C), and keep the area around the chassis as free from dust as is practical.
Planning a proper location for the router and the layout of your equipment rack or wiring closet is
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.
Follow these general precautions when planning your equipment locations and connections:
•
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.
•
Keep the router 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 port adapters and any blank port adapters are in place and secure. The fans direct
cooling air throughout the chassis interior; a loose component or empty slot can redirect the
airflow away from active components.
Rack-Mounting Guidelines
The rack-mounting hardware included with router is suitable for most 19- or 23-inch equipment
racks and telco-type racks. To easily access the interface cables while the router is installed in a rack,
make certain you have access to the rear of the router.
Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the
power strip before installing the router in the rack, and then replace it after the chassis is installed.
As an alternative, you can mount the router on an equipment shelf provided that the rack dimensions
allow you to secure the router to the shelf, and the overall configuration permits safe installation and
access. However, we recommend rack-mounting the router. Figure 2 shows the Cisco 7100 series
router footprint and outer dimensions.
To use the rack-mounting hardware provided with the router, consider the following guidelines:
•
To mount the router between two posts or rails using the brackets, the inner clearance (the width
between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm).
•
The height of the chassis is 3.5 inches (8.89 cm).
•
When mounting the router in four-post or telco-type racks, be sure to use all the screws and the
brackets provided to secure the chassis to the rack posts.
