Chapter 4 Perform Node Acceptance Tests
NTP-G46 Perform the Line Amplifier Node with OSC-CSM Cards Acceptance Test
b. Verify that no equipment (EQPT) alarms appear indicating equipment failure or other hardware
problems. If alarms appear, investigate and resolve them before continuing. Refer to the
Cisco ONS 15454 Troubleshooting Guide or the Cisco ONS 15454 SDH Troubleshooting Guide for
procedures.
Note The OSC terminations created during node turn-up will generate an LOS alarm on the
OSC-CSM card.
Step 5 In node view, click the Provisioning > WDM-ANS > Port Status tabs. Verify that all statuses under
Link Status are listed as Success - Changed, Success - Unchanged, or Not Applicable. If any are not,
complete the following:
a. Delete the two OSC channels using the “DLP-G186 Delete an OSC Termination” task on
page 10-41.
b. Complete the “NTP-G37 Run Automatic Node Setup” procedure on page 3-83.
c. Create the OSC channels using the “NTP-G38 Provision OSC Terminations” procedure on
page 3-84.
Step 6 Create a physical loopback on the west OSC-CSM by connecting the LINE TX port to the LINE RX port
with a fiber and 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
Step 7 Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarm on the west
OSC-CSM card has cleared. The clearing of the LOS alarm indicates that the OSC link is active on the
west side.
Note An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback,
and an LOS alarm will appear for the east OSC-CSM, Port 1 (OSC).
If the alarm clears, continue with Step 8. If not, perform the following steps:
a. Remove the 10-dB bulk attenuator on the OSC-CSM LINE TX and LINE RX ports and reconnect
using only the patchcord.
b. In node view, click the Alarms tab. If the LOS alarm on the west OSC-CSM card clears, continue
with Step 8. If not, continue with Step c.
c. Display the OSC-CSM card in card view.
d. Click the Provisioning > Optical Line > Optics Thresholds tabs.
e. Under Types, click Alarm, then click Refresh.
f. Locate the Port 3 Power Failure Low parameter. Double-click the table cell and change the value to
–30 dBm.
g. Locate the Port 6 Power Failure Low parameter. Double-click the table cell and change the value to
–40 dBm.
h. Click Apply, and then Ye s .
i. In node view, click the Alarms tab. If the LOS alarm on the west OSC-CSM card clears, continue
with Step 8. If not, replace the OSC-CSM card.
