Circuit Board Diagnostics
Diagnostics for the IVP4/6 boards can be run to determine whether everything is
connected properly and that there is a dial tone. To run the IVP4/6 board
diagnostics on all installed boards, follow these steps:
1. Log in to the system and proceed to the Configuration Management
window. (See Chapter 5, System Operations if you need instructions.)
2. Move the cursor to System Control and press
Enter
.
The System Control window is displayed.
3. Move the cursor to Diagnose Equipment and press
Enter
.
The Diagnose Equipment window is displayed.
4. Fill in the fields as follows:
Equipment:
ca
for "card"
Equipment Number:
all
Diagnose Immediately?
yes
A confirmation screen appears stating that immediate diagnosis will
disconnect calls in progress on this card.
5. Press
y
to continue.
6. Press
F3 (SAVE) to begin execution.
The diagnosis takes more than 60 seconds. A working icon appears in
the right hand corner of the screen.
The system searches for dial tones (Loop Current) on the boards and then
informs you if each IVP4/6 board passes the test. If any IVP4/6 board
fails, check to see if it is seated properly. If that does not fix the problem,
you will have to replace the board. If dial tones are not found, check the
Tip/Ring connections.
7. Press
F6 (CANCEL) repeatedly until the Integrated Solution III Menu is
displayed.
8. Select Exit to return to the log on prompt.
Fax Board Diagnostics
Fax board diagnostics provide a way to determine whether or not the fax boards
installed in the system are working properly. These diagnostic capabilities are
available on a per-channel and a per-board basis. That is, you can select which
specific resource to diagnose. The diagnostic tests performed are:
check dma transfers
check interrupts
check onboard RAM
