Overview
1-2 Introduction
Overview
The
B2G124
‐
48P
and
B2H124
‐
48P
are
stackable
switches
that
can
be
adapted
and
scaled
to
help
meet
your
network
requirements.
These
switches
provide
a
management
platform
and
an
uplink
to
a
network
backbone
for
a
stacked
group
of
up
to
eight
B2
switches.
The
switches
also
support
the
use
of
a
redundant
DC
power
supply
to
help
prevent
downtime
due
to
an
internal
power
supply
failure
in
the
switch
or
AC
power
source.
You
can
install
the
switch
on
a
flat
surface
or
into
a
standard
19
‐
inch
rack
with
user
‐
supplied
mounting
hardware,
and
configure
the
switch
functions
using
the
WebView™
application,
CLI
switching
commands,
and/or
SNMP.
B2G124-48P Stackable Switch
The
B2G124
‐
48P
(
Figure 1
‐
1
)
has
several
types
of
front
panel
port
connections,
which
include:
•
Forty
‐
eight
RJ45
ports
(10/100/1000
Mbps,
1000BASE
‐
T
copper
ports)
that
also
support
PoE
for
connections
to
IEEE
802.3af
compliant
PDs
(powered
devices).
•
SFP
slots
that
provide
you
with
the
option
of
installing
Small
Form
Pluggable
(SFP)
Mini
‐
GBICs
for
1000BASE
‐
SX/LX
fiber
‐
optic
connections
and
1000BASE
‐
T
copper
connections.
•
Rear
panel
connectors
for
high
‐
speed
connections
in
a
stack
configuration.
•
Rear
panel
Redundant
Power
Supply
connector
used
to
connect
to
a
SecureStack
Redundant
Power
Supply
(C2RPS
‐
POE).
The
switch
connects
to
the
SecureStack
C2RPS
‐
POE
using
a
SecureStack
C2RPS
‐
POE
Cable.
Note:
The Mini-GBIC ports cannot be active simultaneously with their corresponding
10/100/1000BASE-T ports. For example, if SFP port 48 establishes a link first on the
B2G124-48P, the 10/100/1000BASE-T built-in RJ45 port 48 is not available and
vice-versa.
Caution:
The B2G124-48P and B2H124-48P are PoE-compliant devices. Do not connect
a SecureStack C2 Redundant Power System (C2RPS-SYS) to the power connector.
Otherwise, damage to the device may result.
Precaución:
Los dispositivos B2G124-48P y B2H124-48P
cumplen
con el estándar PoE
(power over ethernet).
No conecte
una fuente de poder redundante (RPS) SecureStack
C2 (C2RPS-SYS) al cable de corriente. De lo contrario, el dispositivo puede dañarse.
