damaged.
This generally indicates a hard-
ware fault. One of the LEDs
will be solid red for three sec-
onds, followed by one second of
another color.
There is a problem with the
serial connection or the set-up
of the serial device.
A rapidly-blinking OK LED
may signal boot failure.

Note the blinking LED and its color, then
contact your dealer or Black Box Techni-
cal Support. The Terminal Server will not
be operational until the fault is fixed.
Check the terminal setup and the physical
connections, including the cable pinouts
(see Appendix 12). Try another serial
device or cable, or cycle power on the
Terminal Server.
Reboot the unit. When the Terminal
Server is running normally, the OK LED
blinks every two seconds.
