The Terminal Server
is connected to a
power source, but
there is no LED
activity.
The unit or its power supply is
damaged.
Contact your dealer or Black Box Techni-
cal Support for a replacement.
The Terminal Server
is unable to com-
plete power-up diag-
nostics.
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.
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.
The Terminal Server
completes its power-
up and boot proce-
dures, but there’s no
noticeable serial
activity.
There is a problem with the
serial connection or the set-up
of the serial device.
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.
A rapidly-blinking OK LED
may signal boot failure.
Reboot the unit. When the Terminal
Server is running normally, the OK LED
blinks every two seconds.
