3.2.3 Ethernet Port LEDs
Both A12U and A08U subsystems come with a RS-232C audio jack serial port that
can be used to assign a permanent IP to the subsystems. After a permanent IP address
has been assigned, an Ethernet cable can be used to connect the RJ-45 Ethernet port
to a network hub or router. This enables you to manage your subsystem locally or
remotely over TCP/IP. See Figure 3- 2 for the locations of the two LED indicators
on Ethernet port. Refer to Table 3-3 for the LED definitions.
