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
