DETAILED STEPS
Step 1
Make sure that the facility power breakers for the upper (Power A) and lower (Power B) power shelves are in the OFF
position.
Step 2 Make sure that I/O switches on the rear of the upper (Power A) and lower (Power B) power shelves are in the OFF
position.
Step 3 Make sure all boards (RPs, PLIMs, SFCs, and FPs) are pulled-out and disconnected from the backplane.
Step 4
If you have a modular configuration DC power system installed:
a) Energize the facility breaker to PM 0, on the upper power shelf, Power A.
b) Measure the voltage at the input terminal block and verify that the DC voltage between the positive and negative
terminals is between 48 VDC and 60 VDC. Make a note of this voltage measurement.
c) Turn the facility breaker to the OFF position.
Caution
Caution
d) Repeat 4a through 4c for each of the remaining DC inputs on the upper power shelf, Power A.
e) Repeat 4a through 4d for each of the DC inputs on the lower power shelf, Power B.
Step 5
Turn the facility breakers for the upper power shelf (Power A) to the ON position. Verify that the Input_OK LED on
all of the PMs installed in the upper shelf are green.
Step 6
Turn the I/O switch at the rear of the upper power shelf (Power A) to the ON position. Verify that the Output_OK LED
on all of the PMs installed in the upper shelf are green.
Step 7
Repeat Step 5 and Step 6 for the lower power shelf (Power B).
Make sure that the facility power breakers for the upper (Power A) and lower (Power B) power shelves
are in the OFF position.
Make sure that I/O switches on the rear of the upper (Power A) and lower (Power B) power shelves are
in the OFF position.
Make sure all boards (RPs, PLIMs, SFCs, and FPs) are pulled-out and disconnected from the backplane.
If you have a modular configuration DC power system installed:
Turn the facility breakers for the upper power shelf (Power A) to the ON position. Verify that the
Input_OK LED on all of the PMs installed in the upper shelf are green.
Turn the I/O switch at the rear of the upper power shelf (Power A) to the ON position. Verify that the
Output_OK LED on all of the PMs installed in the upper shelf are green.
Repeat Step 5 and Step 6 for the lower power shelf (Power B).
Turn the I/O switch at the rear of both upper power shelves (Power A and Power B) to the OFF position.
Verify that none of the Output_OK LEDs on the PMs installed in the shelf are green.
Install all boards (RPs, PLIMs, SFCs, and FPs) in the chassis. For more information, see Installing and
Removing Line Cards, PLIMs, and Associated Components.
Turn the I/O switch at the rear of both power shelves (Power A and Power B) to the ON position.
If you have a modular configuration DC power system installed, measure the input voltage of each DC
input and compare this value to the voltage measurement noted in Step 4. Verify that the equipment is
still receiving the correct input voltage measured in Step 4.
Make sure that the polarity of the DC input wiring is correct.
This is a positive ground system; make sure to connect the positive lead to the +RTN terminal and the
negative lead to the –48V terminal.
