To verify the power, place the black test lead of the voltmeter to the frame ground. Place the red test
lead on the A-side connection and verify that it is between -44 VDC and -52 VDC. Next, place the
red test lead on the B-side connection and verify that it is between -44 VDC and -52 VDC.
Note The voltages -44 VDC and -52 VDC are the minimum and maximum voltages required to
power the chassis. The nominal steady-state voltage is -48 VDC.
To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red
test lead on the A-side return ground and verify that no voltage is present. Place the red test lead on
the B-side return ground and verify that no voltage is present.
To verify the A-side of the shelf, place the black lead of the voltmeter to the frame ground. Place the
red test lead to the BAT1 (A-side battery connection) red cable. Verify that it reads between –44
VDC and –52 VDC. Then place the red test lead of the voltmeter to the RET1 (A-side return ground)
black cable and verify that no voltage is present.
To verify the B-side of the shelf, place the black test lead of the voltmeter to the frame ground. Place
the red test lead to the BAT2 (B-side battery connection) red cable. Verify that it reads between –44
VDC and -52 VDC. Then place the red test lead of the voltmeter to the RET2 (B-side return ground)
black cable and verify that no voltage is present.
This task installs timing cables so that you can provide BITS timing to the
ONS 15310-MA SDH.
