The 10 LEDs on the front of each X-point card indicate the following:
Diode Red LED Green LED
BEAT Blinks when the μController is running
(heartbeat).
SYST.ERR A fault is detected on the card. The
system controller lights, or turns off
this LED. This is used for simplifying
the identification of a module.
SER.CH2 Blinks each time the μController of the
X-point card answers a message from
the system controller on
communication channel 2.
SER.CH1
Blinks each time the μController of the
X-point card answers a message from
the system controller on
communication channel 1.
TEST 1 No special function; for internal testing purpose only.
FAN 2 Fan error, when the fan speed is
outside its normal range. FAN2 is the
innermost fan on the X-point card. The fan speed of FAN2 is in its normal
range. FAN2 is the innermost fan on
the X-point card.
PWR* Any of the voltages on the card is
outside their legal range. All internal voltages are OK.
TEMP The temperature of the card is outside
its legal range. The temperature of the card is OK.
FAN1 Fan error, when the fan speed is
outside its normal range. FAN1 is the
outermost fan on the X-point card. The fan speed of the first fan is in its
normal range. FAN1 is the outermost
fan on the X-point card.
EDH.ERR Indicates EDH status for the selected
monitor output.
The monitoring output monitors the
selected input, but the EDH counter is
on the output.
Note that all alarm ranges are configurable from the system controller.
*:When only a Main X-point module and no I/O X-point module is mounted in a
section, the “PWR” LED of the Main X-point module may indicate an alarm (red)
though everything is all right. The LED will turn green immediately when one I/O
X-point module is mounted in the connected section. This problem has been
resolved for new boards and is valid only with the first release of boards.
3.5.4 Service switch and reset button
There are one slide-switch and one push-button switch on the board, as shown in the figures
below.
