Test 2 External Clocks - Sun Microsystems StorEdge A7000 Manual

Test 2 External Clocks

This test verifies the external clock cables. The test is used to verify either a single
external clock cable or all external clock cables. You select the level of testing during
program initialization. Refer to Chapter 2 for a description of the initialization
options.
The external interrupt acknowledge signals for interrupts 0 and 7 (XIACK0 and
XIACK7) should be connected to the corresponding input signal lines (XIRQ0 and
XIRQ7) and the external clock signal lines (XCLK0 and XCLK1) respectively. Refer to
Chapter 1 for cabling information.
