The minimum and maximum voltages required to power the chassis are –40.5 VDC and –57
VDC respectively. The nominal steady-state voltage is -48 VDC. Note
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 To power up the node, 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, 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.
The voltages –40.5 VDC and –57 VDC are, respectively, the minimum and maximum voltages
required to power the chassis.
Note
b) 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 –40.5 VDC
and –57 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.
Step 5
Return to your originating procedure (NTP).
Shelf Voltage and Temperature
The temperature measured by the TCC2/TCC2P/TCC3 sensors appears on the LCD screen in the ONS 15454
chassis.
Note
The input voltages and temperature of the ONS 15454 chassis are displayed in the Shelf view > Provisioning
> General > Voltage/Temperature pane in CTC. The voltage supplied to the shelf (in millivolts) is displayed
in the Voltage area of the Voltage/Temperature pane. The temperature of the shelf (in degree Celsius) is
displayed in the Temperature area of the pane.
The Voltage/Temperature pane retrieves the following values for the ONS 15454 chassis:
• Voltage A—Voltage of the shelf that corresponds to power supply A, in millivolts.
• Voltage B—Voltage of the shelf that corresponds to power supply B, in millivolts.
• Chassis Temperature—Temperature of the shelf, in degrees Celsius.
In multishelf configuration, the voltage and temperature of each shelf is displayed in the
Shelf view
