Card insertion
To insert an X-point card, slide the module along the plastic guide rails into its position. On
both sides of the card tray there is a hole next to each module slot. Use the two red handles,
which are located on the front of the module to seat the module. When the tip of both
handles is just next to these holes, start to push the handles
simultaneously
inwards the card.
The tip of the handles enters the hole and the card is locked and proper contact ensured
when you hear a click from both handles.
Note that it may be necessary to press hard when inserting the X-point card(s).
Be sure to press the card(s) firmly into the frame, before locking the handles.
3.6.2
Card removal
To remove an X point card from the frame, release the card by pushing the red knobs on
each handle until each handle releases from its locked position. Then pull both handles
simultaneously, and pull the card out of the frame.
3.6.3
Status LEDs
There are 7 LEDs on the front of each Digital Audio X point card:
Figure 14
They 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
No special function; for internal testing purpose only.
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.
Note that all alarm ranges are configurable from the system controller.
