Step 9: Verifying the
Installation
Follow the normal steps for verifying drive installation and operation. Refer to the
drive Hardware Reference and Software Start-up manuals.
Performing Continuity Tests
In these tests you are verifying continuity, a short circuit, between the two test
points. The continuity mode on a digital multi-meter provides the easiest method
for performing this test. Place one meter lead on the first test point and the meter
should beep when you place the other lead on the second test point.
If your meter does not have a continuity mode, you can use a resistance mode.
Place one meter lead on the first test point and the meter should indicate a short
circuit (read approximately zero ohms) when you place the other lead on the
second test point.
