Self-test
When the card is installed, the red Light Emitting Diode (LED) on the
faceplate flashes as the self-test runs. If the self-test completes successfully,
the card is automatically enabled (if the card has been configured in
software). The LED goes out. If the self-test fails, the LED remains lit. The
LED also remains lit if one or more units on the card become disabled while
the card is operating.
Switch settings
The NT5K48 card does not have any option switches. Configure all settings
in software.
