S2 LED is green when at least one alarm source is being monitored (enabled) if the severity level is Info.
S2 LED is amber when at least one event source has triggered if the severity level is Warning.
S2 LED is flashing amber
S2 LED is off when all event sources are disabled if the severity level is Error.
CONSOLE: RJ-45 serial port 115200 baud CLI port. The LIB-306 RJ-45 console port allows root access to
its CLI (Command Line Interface) via a computer, regardless of the state of the switch (unless it is
completely dead). By connecting to the console port, out-of-band remote access to the CLI of the switch is
possible. This creates a secondary path to the switch outside the bandwidth of the network, which needs to
be secured without relying on the primary network.
ALARMS: Alarm inputs and outputs are RJ-45 connector with 2-IN and 2-OUT; 10-30VDC, 40mA
maximum; optically isolated from main board. You can connect up to two alarm inputs from external devices
in your environment (e.g., a fire alarm, a door, a temperature gauge) to the alarm input port on the switch
front panel. The figure below shows the location of the alarm pinouts. For each alarm input, you can
configure an open or closed circuit to trigger an alarm and configure the severity of the alarm. A triggered
alarm generates a system message. If you enter a descriptive name for the alarm, that name is included in
the system message. A triggered alarm also turns on the LED display. The LED is normally off, meaning no
alarm condition exists.
You can set the alarm severity to Info, Warning, or Error. The severity is included in the alarm message and
also sets the S2 LED color when the alarm is triggered. The S2 LED is
Warning alarm, and blinking
You can use the LIB-306 web GUI or CLI to configure alarm contacts; see the related manual for details.
The ALARMS port pinning and basic block diagram are shown below.
The Alarm Input and Output truth tables are provided below.
