B2G124-24
C2RPS-PSM
This 150-watt DC power supply can be used as redundant power for any
of the SecureStack C2 or B2 non–Power-over-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-over-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.

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 or A2
