Figure 22: Port Types
• The Management port is a 10/100 Ethernet port which is a channel to download images
and manage the system. This port is provisioned with an RJ-45 jack on the front panel.
You must provide a CAT5 Ethernet cable to connect to the port.
• The Console port is a Universal Asynchronous Receiver/Transmitter (UART) port used to
configure switch and system parameters and can be also be used for monitoring purposes.
The console port is enabled by default. The default Baud rate is 115,200. This port is
provisioned with an DB-9 connector. Connect the console port to a terminal with an RS-
232 serial cable.
The DTE/DCE switch on the front panel controls the serial port type as either data
terminal equipment (DTE) or data communications equipment (DCE).
Flip the switch to DTE when connecting to the serial port of a PC with a null modem
cable. Flip the switch to DCE when connecting to the serial port of a PC with a straight-
through cable.
The port is configured as DTE or DCE depending on the switch setting. No crossover
cables are required.
• The Alarm port is provisioned as a DB-9 serial port and is used to connect to external
alarm devices that report conditions that trigger red or amber alarms. You must provide an
appropriate cable configured according to your alarm panel.
