Chapter 5: Operation
wait for this prompt character before sending each and every command to the A/B Switch. All commands are
case insensitive and can be entered in upper or lower case. Note however, that password parameters are case
sensitive. All commands must be terminated with a carriage return (ASCII 13 or hex 0x0D) before they will be
accepted by the A/B Switch. Several commands can be abbreviated by using just the first character of each
command word, for example the set/get system commands can be abbreviated using “g s” for “get system” or
“s s a” for “set system a”.
5.4 Ethernet Switching (SW1046A)
A/B Switch models (SW1046A) that support Ethernet remote control can be switched using commands sent
over an Ethernet network. In order to use the Ethernet Network port on the A/B Switch you must set the
IPADDRESS, SUBNETMASK, and GATEWAY address parameters before connecting to your network. See Section
6 for more details on how to do this. After setting up the system and powering up for the first time, you may
also need to change other parameters for your application. All configuration parameters are stored in non-
volatile memory. They are immediately active when a change is made, but they will not become permanent
until the SAVE command, followed by the RESET command has been executed.
Once the Ethernet remote control port has been configured, the A/B Switch can be switched using SNMP
commands—see the MIB path summary in the appendix for a list of SNMP variables and their functions.
The A/B Switch also supports remote telnet access, and can be controlled via a telnet session using the same
commands as supported by the RS-232 serial interface. Refer to Section 7 for the complete list of console
commands.
As an additional option, A/B Switch models that support Ethernet remote control also include a built-in http
server application that allows all of the console commands listed in section 7 to be accessed via a web browser
interface. See Section 8 for more details about the web browser interface feature.
NOTE: The NETWORK port on the A/B Switch is 10BASE-T only. The STATUS LED will blink whenever the A/B
Switch receives a command from the Ethernet network interface or from the serial RS232 interface. In
addition the STATUS LED will blink when a switching command is issued via the remote control contacts
or front panel push button switches.
The A/B Switch also has the ability to issue either SNMP traps, or UDP syslog messages. These messages can be
sent to one or more network administrator systems to provide notification when the A/B Switch changes
connection states either automatically (auto bypass switching or auto recovery switching) or via manual control
(front panel toggle switch or commands received on the RS232 or Ethernet interfaces), and when certain other
events occur. See Section 10 and Section 11 for additional details.
To restrict access to the A/B Switch, each of the Ethernet interface options (SNMP, telnet, and web browser) can
be independently enabled/disabled, and if enabled, can be configured to require a login password. Additionally,
user access can be restricted by IP address so only commands received from pre-defined “administrator” IP
addresses will be acknowledged and acted upon. See section 7 for additional information regarding these
commands.
5.5 Automatic Switching
The A/B Switch models that support Ethernet remote control can also be configured to automatically switch
between a “normal” connection state (port C connected to port B) and a “bypass” or “failover” connection state
(port C connected to port A). User configurable failover and recovery parameters control the auto-switching
functions to allow the switch to be used in a variety of applications. In order to be able to perform the auto
bypass and auto recovery switching functions, the A/B Switch issues ICMP echo request (PING) packets from its
Ethernet network interface to a user configurable IP address on the network. If the “normal” network path
connections between the A/B Switch and the device being monitored go down for any reason, the A/B Switch
will no longer be able to PING the specified IP address, and will then automatically switch from the “normal”
connection state (port C connected to port B) to the “bypass” or “failover” connection state (port C connected to
port A). Once the problems on the primary path have been identified and corrected, the user can issue a
