LED indicators

These show the current status of a serial port or the Ethernet connection. Details of
how to interpret the information displayed are given later in this Chapter. The LEDs
can also show diagnostic information, as described in Chapter 17, Troubleshooting.

Alphanumeric display

If the alphanumeric display shows a number, the information shown on the LED indi-
cators relates to the serial port of that number. For example, if it shows 16, the infor-
mation on the LED indicators is for Port 16.
If the alphanumeric display shows EA, the information shown on the LED indicators
relates to Ethernet Activity.
If the alphanumeric display shows PU, the LED indicators show Processor Utilization
in a bar graph-like presentation. The more LEDs that are lit, the greater the CPU activ-
ity.
If the alphanumeric display shows AC, PortServer II has powering up and is now in
normal operating mode.
Other indications on the display identify possible fault conditions. Refer to Chapter
17, Troubleshooting for information on fault codes.
