Cisco 3000 Series User Manual

General Site
Requirements
Site Environment
The location of individual chassis and the
layout
of
your
equipment
rack
or
wiring
room are
extremely important
for
proper
system operation Equipment placed
too
close
together inadequate
ventilation
and inaccessible
panels
can cause
system
malfunctions and
shutdowns and
can
make
system
maintenance
difficult
When
planning
your
site
layout
and
equipment locations
use the
following precautions
to
help
avoid
equipment
failures and reduce the likelihood of
environmentally
caused shutdowns
If
you
are
currently experiencing
shutdowns or
unusually high errors
with
your
existing equipment
these
precautions may
help
you
isolate the
cause
of failures and
prevent
future
problems
Preventive Site
Configuration
The
following precautions
will
help you plan
an
acceptable operating
environment for
your
router
and will
help you
avoid
environmentally
caused
equipment
failures
Remember that electrical
equipment generates
heat Ambient air
temperature
might
not be
adequate
to cool
equipment
to
acceptable operating temperatures
without
adequate
circulation
Ensure
that the
room
in which
you
operate
your
system
has
adequate
air circulation
Always
follow the
ESD-prevention procedures
in the section
Preventing
Electrostatic
Discharge Damage
to
avoid
damage
to
equipment Damage
from static
discharge
can cause
immediate or
intermittent
equipment
failure
Ensure that
the
chassis cover
is
secure The chassis is
designed
to
allow
cooling
air to flow within
An
open
chassis allows air
leaks
which
may
in turn
interrupt
and redirect the flow of
cooling
air
across
internal
components
Equipment
Racks
The
following tips
will
help
you
plan an acceptable equipment
rack
configuration
Enclosed racks must have
adequate
ventilation Ensure that the rack is not
overly congested
because each unit
generates
heat An enclosed rack should have louvered sides and fan to
provide
cooling
air
When
mounting
chassis in
an
open
rack ensure
that the rack frame does not block the intake
or
the exhaust
ports
If the chassis is installed
on slides
check the
position
of the chassis when it
is seated all the
way
into the rack
In
an
enclosed rack with ventilation fan in the
top
excessive heat
generated by equipment
near
the bottom of the rack
can
be drawn
upward
and into the intake
ports
of the
equipment
above
Baffles
can
help
to isolate exhaust air from intake
air
which also
helps
to draw
cooling
air
through
the chassis The best
placement
of the baffles
depends upon
the air flow
patterns
in the
rack
which
can
be found
by
trial-and-error
When
equipment
installed in rack
fails
particularly
in
an
enclosed
rack
try
operating
the
equipment by
itself
if
possible
Turn
off other
equipment
in the rack
and
in
adjacent racks
to
allow the unit
under
test maximum of
cooling
air
and clean
power
Power
Supply
Considerations
Check the
power
at
your
site to ensure that
you
are receiving
clean
power
free
of
spikes
and
noise
Install
power
conditioner if
necessary
Install
proper grounding
to avoid
damage
from
lightning
and
power surges
