Easily switch between
active and fallback
systems.
Each chassis holds up
to 16 interface rack
cards.
Daisychain up to 64
chassis for control of
up to 2048 switching
channels.
Great for maintenance!
When your primary
system’s ports need
attention, you can
switch to alternate
lines.
Individual, rack-level,
and system gangswitching.
T
he BLACK BOX®Automatic
Switching System provides
highly reliable gang switching
control between primary and
backup circuits.
A wide range of applications
The Automatic Switching
System is ideal for disaster
recovery, enabling you to switch
to a backup system when the
primary system goes down.
The system is also great for
maintenance. When your primary
system’s ports need attention,
simply switch to alternate lines.
The Automatic Switching
System has countless applications in commercial, industrial,
and government—anywhere
system availability is crucial.
And redundant power supplies
increase reliability for missioncritical applications.
Modular construction
The modular construction of
the system enables you to install
a wide range of interfaces in a
compact rackmount chassis,
providing maximum flexibility for
you as your system grows or
changes.

AUTOMATIC SWITCHING SYSTEM
Local and remote switching
up to 2048 ports.
Key Features
AUTOMATIC SWITCHING SYSTEM
A typical Automatic Switching
System includes a rackmount
chassis, a control card, one or
two power supplies, and up to
16 switching interface cards.
You can daisychain up to 64
chassis and control up to 2048
switching channels with a master
switch! The optional Dual
Redundant Power Supply
provides power to up to eight
daisychained chassis.
Interface cards are hot
swappable—simply pop in a
different card. There are no wires
to disconnect, and you don’t have
to power down to make changes
to the system.
Many interface options
The wide range of interface
cards include RS-232/V.24,
RS-449, RS-530, Twinax, BNC,
V.35, T1, RJ-11, RJ-45 (CAT5)—
even an SVGA Video Card, which
enables you to switch between
two high-resolution video interfaces. All interface cards are fully
transparent to communications
speeds, protocols, and formats.
Some interfaces are available
as dual cards, doubling interface
density per chassis. For maximum
versatility, you can mix different
kinds of interface cards within the
chassis.
Switch one or switch many
The system enables you to
switch individual interface cards,
a group of interface cards, an
entire chassis, even an entire
rack of chassis! You’re in control.
Each chassis has a security
key switch to prevent accidental
switching, and all cards feature

Local or remote operation
Control the Automatic
Switching System locally or via a
Web browser, Telnet™, SNMP, or
for some control cards, through
Configuration Software (SM540A).
Local control is through
manual toggle switches. LEDs
show each current switch
position, so you can quickly see
the status of the entire chassis.
Remote control cards enable
you to control the system via a
Web browser through your 10-/
100-Mbps Ethernet network
or across the Internet. The Web
browser interface features an
intuitive graphic interface that
enables you to switch and
monitor multiple chassis.
You can also control the
system with a standard Telnet
command-line interface through a
terminal connected to the RS-232
port. Plus, SNMP provides industry standard SNMP management
compatible with a wide range of
management software such as
HP
®
OpenView®.
For the SM533-C and SM534-C
control cards, Configuration
Software runs on a local area
network and gives you customized switching control through a
PC-based graphical interface with
point-and-click operation.
