5.4 Remote Ethernet Management (NBS004MA, NBS006MA, NBS008MA, NBSALL8MGR, or
NBS016MA Models Only)
To use the Ethernet Network port, you must set the IPADDRESS, SUBNETMASK and GATEWAY address of the switch before
connecting to your network. See Chapter 6 for more details.
connecting to your network. See Chapter 6 for more details.
The switch can be remotely controlled using SNMP commands over a TCP/IP Ethernet network. See the MIB path summary in the
appendix for a list of SNMP variables and their functions. The switch also supports telnet access, and can be controlled via a telnet
session using the same enhanced command set as used by the RS-232 serial interface. The switch also includes a built in http
server that allows all of the commands available via the RS-232 serial port to be accessed via a web browser interface. See
Chapter 8 for more details about this feature.

The NETWORK management port on the switch is 10BASE-T only. There are two status indicators that function as follows. The
LINK LED is on whenever the switch network interface is ready for communication. This should happen very shortly after power
on, and should only go out if there is some problem with the interface detected by the unit.

NOTE: The LINK LED does not indicate that a valid network connection is made. The ACT LED will blink whenever the switch
receives a command from the network interface.
NOTE: Only access to variables on the ‘private’ branch will trigger the ACT LED (OID 1.3.6.1.4…). In addition, the ACT LED will
blink when a switching command is issued via the serial port.
After the switch has been configured and is ready to be accessed via the serial or Ethernet interfaces, you may need to change
other parameters to configure the switch features that you will be using in your application. These parameters are stored in
non-volatile memory. Note, however that although they are immediately active when a change is made, they will not become
permanent until the SAVE command, followed by the RESET command is performed.

5.5 Automatic Switching (NBS004MA, NBS006MA, NBS008MA, NBSALL8MGR, or NBS016MA Models
Only)
Switch models that are network manageable (that support Ethernet remote control) can also be configured to automatically
switch between a “normal” connection state (all COMMON ports are connected to their respective B ports) and a “bypass” or
“failover” connection state (all COMMON ports are connected to their respective A ports). User configurable failover and recovery
parameters control the auto-switching functions to allow the switch to be used in a variety of applications.
