Chapter 1 Install the Shelf and Common Control Cards
NTP- G19 Turn On and Verify Office Power
DLP-G19 Turn On and Verify Office Power
Caution
Do not apply power to the shelf assembly until you complete all installation steps.
Step 1
Using a voltmeter, verify the office battery and ground at the following points on the fuse and alarm
panel:
a.
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 –40.5 VDC and –57 VDC. Place the red
test lead on the B-side connection and verify that it is between –40.5 VDC and –57 VDC.
Note
The minimum and maximum voltages required to power the chassis are –40.5 VDC and
–57 VDC respectively.
b.
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. The voltmeter must read
0 VDC. Place the red test lead on the B-side return ground and verify that no voltage is present. The
voltmeter must read 0 VDC.
Step 2
Insert the fuse into the fuse position according to site practice. The fuse rating must not exceed 30A
.
Step 3
At the bottom rear of the shelf assembly, remove the cover panel to access the power connections.
Step 4
Using a voltmeter, verify the ONS 15454 shelf for –48 VDC battery and ground:
a.
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
–40.5 VDC and –57 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.
Note
The voltages –40.5 VDC and –57 VDC are, respectively, the minimum and maximum
voltages required to power the chassis.
Purpose
This task measures the power to verify correct power and returns for the ONS
15454 shelf.
