SecureStack B2 Switch Family
B2G124-24
This switch features 24 ports of 10/100/1000
connectivity, four uplink ports supporting
SFP (Small Form-factor Pluggable) GBICs
and two integrated stacking ports. Ports 21
thru 24 on this model have the flexibility
to be mapped as either 10/100/1000 ports
or as optical Gigabit Ethernet ports with
the installation of a fiber transceiver in the
appropriate SFP socket.
B2G124-48
This switch features 48 ports of 10/100/1000
connectivity, four uplink ports supporting
SFP (Small Form-factor Pluggable) GBICs
and two integrated stacking ports. Ports 45
thru 48 have the flexibility to be mapped as
either 10/100/1000 ports or as optical Gigabit
Ethernet ports with the installation of a fiber
transceiver in the appropriate SFP socket.
B2G124-48P
This switch features 48 ports of 10/100/1000
with Power-over-Ethernet capability, four
uplink ports supporting SFP (Small Form-
factor Pluggable) GBICs and two integrated
stacking ports. Ports 45 thru 48 have the
flexibility to be mapped as either 10/100/1000
ports or as optical Gigabit Ethernet ports
with the installation of a fiber transceiver
in the appropriate SFP socket.
B2H124-48
This switch features 48 ports of 10/100
Base-TX connectivity, four uplink ports
supporting SFP (Small Form-factor
Pluggable) GBICs and two integrated
stacking ports. The SFP ports support various
optical Gigabit Ethernet solutions with the
installation of a fiber or copper transceiver
to increase the total number of ports to 52.
B2H124-48P
This switch features 48 ports of 10/100Base-
TX with Power-over-Ethernet capability,
four uplink ports supporting SFP (Small
Form-factor Pluggable) GBICs and two
integrated stacking ports. The SFP ports
support various optical Gigabit Ethernet
solutions with the installation of a fiber or
copper transceiver to increase the total
number of ports to 52.
C2RPS-PSM
This 150-watt DC power supply can be used
as redundant power for any of the SecureStack
C2 or B2 non-Power- o v e r-Ethernet switches
(B2G124-24, B2G124-48, and B2H124-48).
The 150-watt power supply can be mounted
in a SecureStack RPS chassis (C2RPS-SYS,
C2RPS-CHAS8 or C2RPS-CHAS2). A
single RPS can power a switch that loses
AC power.
C2RPS-SYS
This SecureStack RPS bundle includes a
chassis (C2RPS-CHAS8) that supports up
to eight individual 150-watt redundant
power supplies (C2RPS-PSM). The bundle
includes the basic chassis, which can be
rack mounted, and one 150-watt redundant
power supply.
C2RPS-POE
This 500-watt DC power unit can be used as
redundant power for any of the SecureStack
C2 or B2 Power- o v e r-Ethernet switches
(B2G124-48P or B2H124-48P). Since the
B2 PoE switches provide up to 360 watts
of PoE power, a much larger redundant
power supply is required. This RPS is a
rack-mountable unit and does not require
an additional chassis.
C2RPS-CHAS8
This SecureStack RPS power chassis supports
up to eight individual 150-watt redundant
power supplies (C2RPS-PSM). RPS units
are mounted vertically in the chassis.
C2RPS-CHAS2
This SecureStack RPS power chassis supports
up to two individual 150-watt redundant
power supplies (C2RPS-PSM). RPS units
are mounted horizontally in the chassis.
Stacking Notes
• Stacking cables must be ordered to
stack the SecureStack B2.
• The SecureStack B2 uses the same
stacking cable as the SecureStack C2
(C2CAB-SHORT or C2CAB-LONG).
• The SecureStack B2 cannot be stacked
with a SecureStack C2.
