Required Network Information

After you install the chassis, your system administrator must configure the individual and system
interfaces before you connect your system to external networks. Refer to the following documentation
for configuration information.

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 uBR7200 series router off the floor and out of any area that tends
to collect dust, excessive condensation, or water.
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,
cable clock card, blank cable clock card, cable interface line cards, any blank interface cards, 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 airflow away from
active components and cause overheating.
Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner and appropriate surge suppression if
necessary.
Install proper grounding to avoid damage from lightning and power surges.
