Physical
Description
Route
Switch Processor
The
RSP2
shown
in
Figure
1-8
is
the
main system
processor
in
the router
The
RSP2
contains
the
system
CPU
and
system
memory
components
It
maintains
and
executes
the
management
functions
that
control
the
system The
system
software
is
contained
on
the
RSP2
in
either
Flash
memory
single
in-line
memory
module
SIMM
or
in
Personal
Computer
Memory
Card
International
Association
PCMCIA
Flash
memory
card
The
RSP2
contains
the following
components
OrionIR4600
Reduced
Instruction
Set
Computing
RISC
processor
used
for
the
central
processing
unit
CPU
The
CPU
runs
at
an external
clock
speed
of
50 megahertz
MHz
and
an
internal
clock
speed
of
100MHz
Most
of the
memory
components
used
by
the
system
including
the
onboard
Flash
memory
SIMM
Air-temperature
sensors
for
environmental
monitoring
In addition
to
the preceding
system
components
the
RSP2
contains
and
executes
the following
management
functions
that
control
the
system
Sending
and
receiving
routing
protocol
updates
Managing
tables
and
caches
Monitoring
interface
and
environmental
status
Providing
Simple Network
Management
Protocol
SNMP
management
and
the console/Telnet
interface
Note
The
RSP2
must be
installed
in
RSP
slot
or
RSP
slot
both
of
which
are
clearly
labeled
RSP
During
operation
the system
will
hang
if
the connection
between
the
RSP2
connector
and
any
of the
backplane
pins
is
interrupted
To
maintain
proper
airflow
through
the chassis
and
card
cage
an
RSP
filler
blank
MAS-RSPBLANK
is
required
in the
RSP
slot
adjacent
to
the
RSP2
and
ships with
each
single-RSP2
system
The
high-speed
switching
section
of the
RSP2
communicates
with
and
controls
the interface
processors
on
the
CyBus
This
section
decides
the destination
of
packet
and
switches
it
based on
that
decision
The
RSP2
uses
16-million-instructions-per-second
mips
processor
to
provide
high-speed autonomous
switching
and
routing
The
single
enabled
LED
lights
to
indicate
that
the
RSP2
is
enabled
for operation
