Port Status LEDs
The port status LEDs are used in several ways. During the initialization
process, the LEDs indicate that self-tests are being performed, and if any
self-test fails, they indicate an error code. After the unit has received a load
image and parameters, the lights indicate when a port is actively being used.
In this case, each light can indicate activity for more than one port. For
example, if LED 1 is lit, this can indicate that there is activity on ports 1, 11,
21, or 31. LED 2 indicates activity on ports 2, 12, 22, etc.
Connect Serial Device Cables
Connect the serial device cables to the 8-pin RJ-45 jacks on the rear of the
unit. The signal assignments of the 8-pin jacks are shown in Figure 8.

Configuration Guide for information about setting up flow
and modem control.
