, depending on the secondary frame
you are working on.
v
PCC in the failing frame.
v
PCC, AC module or SPCN panel card in the preceding frame in the
frame string.
v
SPCN frame-to-frame cable.
This ends the procedure.
28.
Perform the following:
a.
Follow the SPCN frame-to-frame cable back to the preceding frame in the
string.
b.
Disconnect the SPCN cable from J16 on the PCC, AC module, or SPCN
card.
c.
Connect the negative lead of a multimeter to the frame ground.
d.
Connect the positive lead of a multimeter to pin 2 of J16.
Note:
Use an insulated probe or jumper when performing the voltage
readings.
e.
Note the voltage reading on pin 2.
f.
Move the positive lead of the multimeter to pin 3 of J16.

Exchange the SPCN frame to frame cable power control compartment,
AC module, or SPCN card in the frame from which you removed the
SPCN optical adapter. See the removal and installation procedures in
this book or in the
Migrated Expansion Tower Problem Analysis, Repair
and Parts
, depending on the secondary frame you are working on.
This ends the procedure.
29.
Exchange the power control compartment, AC module, or SPCN card
(BKSPCN for the system or TWRCARD in a FC 5065 tower) from which you
disconnected the SPCN cable in step 28 of this procedure. See the removal and
installation procedures in this book or in the
