Chapter 1 Install the Cisco ONS 15454 Shelf Assembly
Step 7 Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation-prevention grease to keep the
connections noncorrosive.
Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention

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.
b.
Step 2 To power up the node, insert the fuse into the fuse position according to site practice. The fuse rating

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 voltages –40.5 VDC and –57 VDC are, respectively, 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.
