RPS Deployment Strategies
1-4 Introduction
RPS Deployment Strategies
The
RPS
can
be
deployed
in
a
variety
of
situations
with
mission
‐
critical
applications.
For example:
•
For
use
in
a
voice
and
data
network
where
switches
are
connected
to
IP
phones
and
PCs.
Connecting
an
RPS
to
the
switches
can
prevent
voice
network
failures
caused
by
switch
power
failures.
•
For
use
in
traditional
data
10/100/1000
Ethernet
switches
carrying
mission
‐
critical
data.
Figure 1
‐
6
shows
an
example
of
the
RPS
providing
redundant
power
backup
for
two
SecureStack
C2
switches.
If
a
SecureStack
C2
switch
device
experiences
an
internal
power
‐
supply
failure,
the
following
occurs:
1.
The
internal
DC
‐
power
source
of
the
switch
device
is
immediately
switched
over
from
the
internal
DC
‐
power
supply
to
the
RPS
DC
‐
power
input.
2.
The
switch
device
saves
this
status
information
for
future
retrieval,
if
necessary.

The C2RPS-PSMs used in C2RPS-CHAS2 are interchangeable with those used in
the C2RPS-CHAS8 chassis available from Enterasys Networks.
