TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT113-100/101; however,
we would like to offer suggestions for the following
:
•
8.1 LED IS NOT LIT
•
8.2 LED IS BLINKING RED
•
8.3 NO SOUND
•
8.4 SOUND DISTORTION
•
8.5 SOUND LEVEL IS LOW
8.1 LED IS NOT LIT
A) Cause 1: Card cage is not plugged in.
Solution: Plug card cage in. If the LED
lights, the problem is solved. If
the LED is still not lit, see
Cause 2.
B) Cause 2: Card is not plugged in all the
way.
Solution: Push the card in all the way. If
the LED is still not lit, see
Cause 3.
C) Cause 3: Card cage slot has a problem.
Solution 1: Test the card in other slots of
the card cage. If the slot was
damaged, the card may work in
other slots. If other slots work
and the LED lights, the problem
is the card cage slot. The card
cage may require service. Call
ALTINEX at [phone]. If
the other slots do not work and
the LED is still not lit, see
Solution 2.
Solution 2: Take any other known good
card with an LED and verify that
the slot used is good by seeing
if the other card’s LED lights
in that slot. If it lights, then the
original card may be the source
of the problem. Call ALTINEX at
[phone].
8.2 LED IS BLINKING RED
If the LED on the card is blinking red, find the error
code. For example, if you are using card 5 of unit
1, send the
[C5U1] command to see the status and
error code. Note that card 5 refers to slot 5.
A) Cause 1: The CPU on the card is not
working properly.
- If the CPU is not working, you
will receive an ER01 message.
The system will return feedback
as [
On1 ER01 C05] when
using card 5 of unit 1.
-
ER01 Code: CPU error
Solution 1: Look at the card and verify that
there is no damage. If there is
no damage, see Solution 2.
Solution 2: Verify that all IC’s are seated in
their sockets. If the LED is still
blinking red, see Solution 3.
Solution 3: Call ALTINEX at [phone].
B) Cause 2: The MT113-100/101 card and its
serial device are not
communicating.
- If there is no communication
between the MT113-100/101
card
and its serial device, you
will receive an ER02 message.
The system will return
feedback as [
On1 ER02 C05]
when using card 5 of unit 1.
- ER02 Code: Communication
error between the MT113-
100/101
card and its serial device.
