Identify a transmit port on an AD-xC-xx.x, 32DMX-O, 32DMX, or 4MD card in the node that you
want to test and connect it to the optical power meter.
Read the values displayed on the optical power meter. These values must be consistent with the data
provided by the MetroPlanner installation file, +/– 1 dB. To view MetroPlanner values, click the
Provisioning > WDM-ANS > Provisioning tabs. For 32DMX-O and 32DMX cards, the values are
listed in the Channel x Drop Power field (dwdm.rx.power.DropChxW/E) where x = 1 to 32. For
OADM cards, the fields are listed in the Band [x] Drop (dwdm.rx.power.DropBxW/E) field where
x = 1 to 8.

Check the fiber connections between the OPT-BST amplifier or the OSC-CSM card and the
OPT-PRE amplifier or the next OADM card.
Check the fiber connections between the OADM cards and if needed clean the connectors. See the
"NTP-G115 Clean Fiber Connectors" procedure on page
From the 32DMX-O or 32DMX card view, choose the Provisioning > Optical Chn > Parameters
