AT&T IPC-1600 manual Assigning Board-Unique Hardware Interrupt Request Level

Installation Procedures

Assigning Board-Unique Hardware Interrupt

Request Level

If you specified board-unique hardware interrupt assignments, the system now displays a list of available hardware interrupts and prompts you to enter the interrupt number to be assigned to the first board that you wish to install. At the factory the hardware is set to IRQ10; if IRQ10 is already assigned, the first available interrupt in the displayed list appears as the default. The hardware IRQ setting(s) will be set in Chapter 4 to match the IRQ assignment(s) made in this chapter.

The following is an example of how the display and prompt may appear on your screen:

Please enter the following system configuration information for IPC-1600 Board 1. The available interrupt(s) for the IPC-1600 Board 1 are:

IRQ 3

IRQ 5

IRQ 10 (default)

IRQ 11

IRQ 12

Type the interrupt number and strike the ENTER key or type Q to cancel installation. Striking the ENTER alone will select the default.

Enter Interrupt:

Either press the ENTER key (to enter the default) or type in the name of the interrupt that you wish to assign and then press ENTER.

Again, write down the IRQ settings so that you may refer to your records during the hardware installation.
