SUMMARY STEPS
1.
Make sure all boards (RPs, PLIMs, SFCs, and FPs) are pulled-out and disconnected from the backplane.
Verify that the three status LEDs on the front of each power module are off.
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.
3.
If you have a DC power system installed, perform the following steps:
4.
If you have an AC power system installed, perform the following steps:
5.
Verify that the fan tray and fan controller LEDs are on and that the fans are running.
6.
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.
7.
Install all boards (RPs, PLIMs, SFCs, and FPs) in the chassis. For more information, see
Installing Line Cards, PLIMs, and Associated Components.
8.
Turn the I/O switch at the rear of both power shelves (Power A and Power B) to the ON position.
DETAILED STEPS
Step 1
Make sure all boards (RPs, PLIMs, SFCs, and FPs) are pulled-out and disconnected from the backplane. Verify that the
three status LEDs on the front of each power module are off.
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
If you have a DC power system installed, perform the following steps:
a) Insert the power fuse at the BDFB or power plant to energize 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.
Make sure that the polarity of the DC input wiring is correct.
Caution
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.
Caution
c) Verify that the correct Input OK LED on PM is lit.
d) Repeat Step a through Step c for each of the remaining DC inputs on the upper power shelf, Power A.
e) Repeat Step a through Step d for each of the DC inputs on the lower power shelf, Power B. When power shelf B has
been completed go to Step 5.
Step 4
If you have an AC power system installed, perform the following steps:
a) Open the circuit breaker for each feed on the PDU (6) A and B or the 12 individual single phase inputs at the circuit
breaker cabinet.
b) If you are using the Cisco AC PDU, connect the 3 phase Delta or Wye plug into the source outlet.
c) Energize the office three phase breakers for sides A and B.
d) Close PM 0 (AB) on the left side PDU (power shelf A) and verify that the In OK LED is on for the PM that is
energized.
e) Repeat Step d for PMs 1-5 on side A and for PMs 0 - 6 side B.
