3.2.2 RS232 (Console)
The port labeled “Console” is an RS232 serial port used for initial configuration and
debugging. Upon first installation of the system, you need to connect a PC to this interface and
configure network parameters for remote connections. Refer to Section 2.9.1 to view the full pro-
cedure.
3.2.3 Management
The RJ45 Ethernet port labeled “MGT” provides access for remote management. The man-

The management port network attributes (such as IP Address) need to be pre-configured via the
RS232 console port before using the port. Refer to Section 2.9.1 to view the full procedure.
