Warning
Before
working
on
equipment
that is connected to
power
lines remove
jewelry including
rings necklaces
and
watches
Metal
objects
will heat
up when
connected to
power
and
ground
and
can cause
serious burns or weld the metal object to the terminals
Preparing
for Installation 2-1
Safety
Recommendatons
Follow these
guidelines
to ensure
general safety
Keep
the chassis
area
clear and dustfree during
and
after installation
Put
the removed chassis
cover
in
safe
place
Keep
tools
away
from walk
areas where you and others could
trip
over
them
Do not wear
loose clothing
that could
get caught
in the chassis Fasten
your
tie
or scarf
and
sleeves
Wear
safety glasses
when
working
under
any
conditions that
might
be hazardous
to
your
eyes
Do not
perform
any
action that creates
potential
hazard to
people
or
makes the
equipment
unsafe
Safety with Eectricity
Follow these
guidelines
when
working
on
equipment powered by electricity

General Site
Requirements
Locate the
emergency
power-off switch
in the
room
in which you
are working Then
if
an
electrical accident
occurs
you
can
act
quickly
to
shut the
power
off
Before
working
on the
system
turn off the
power
and
unplug
the
power
cord
Disconnect all
power
before
doing
the following
Installing or
removing
chassis
Working
near
power supplies
Performing software upgrade
Do not work alone when
potentially
hazardous conditions exist
Never

Always
check
Look
carefully
for
possible

as follows
Use caution

Turn
off

If
possible
send another person

Prevendng
Eectrostatc
Discharge Damage
Electrostatic
discharge ESD can damage
equipment
and
impair
electrical
circuitry
It
occurs
when
electronic printed circuit cards
are
improperly
handled and
can
result in
complete
or
intermittent
failures
Always
follow ESD
prevention
procedures
when
removing
and
replacing
cards Ensure that the
chassis is
electrically
connected to earth
ground
Wear an ESD wrist
strap ensuring
that it makes
good
skin contact Connect the
clip
to
an
unpainted
chassis frame surface
to safely
channel unwanted
ESD
voltages
to
ground
To
properly guard against
ESD
damage
and
shocks
the wrist
strap
and cord
must
operate effectively
If
no
wrist
strap
is
available
ground yourself by touching
the metal
part
of the chassis
Genera Site
Requirements
This section describes the requirements your
site must meet for safe installation and
operation of
your system
Ensure that
your
site is
properly prepared
before
beginning
installation
The
router can be used as desktop or rack-mounted equipment in data processing or lab
environment
Optional
rack-mount kits
are available
For
desktop mounting
use
the rubber
feet
provided They protect the chassis
and
provide
nonskid
surface for the chassis

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
