Chapter 4 Perform Node Acceptance Tests
DLP-G311 Verify the East ROADM Add/Drop Channels
Step 3
Wait 2 to 3 minutes, then click the
Alarms
tab. Verify that the LOS alarm on the east OSCM or
OSC-CSM, and the OPT-BST cards have cleared. The clearing of the LOS alarm indicates that the OSC
link is active on the east side.
Note
An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback.
Step 4
If you are using a tunable laser, follow the manufacturer’s instructions to complete the following steps.
If you are using a TXP_MR_2.5G card, continue with
a.
Set the output power to a nominal value, such as –3 dBm.
b.
Set the tuner to the wavelength you are testing, then continue with
Step 5
If you are using a TXP_MR_2.5G card, complete the
“DLP-G268 Provision TXP_MR_2.5G Cards for
Acceptance Testing” task on page 4-4
for the TXP containing the wavelength you will test. Refer to
, if needed.
Step 6
If you are using a TXP_MR_2.5G card, connect the TX port to a power meter and record the output
power.
Step 7
Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the east side fiber
patch panel MUX port that corresponds to the east 32WSS card port carrying the tested wavelength.
Step 8
Connect the TXP_MR_2.5G DWDM RX port or the power meter RX port to the east side fiber patch
panel DMX port that corresponds to the east 32DMX card port carrying the tested wavelength.
Step 9
Display the east 32WSS in card view.
Step 10
Click the
Maintenance
tab.
Step 11
For each wavelength that you will test, click the table cell under Operating Mode and choose
Add Drop
from the drop-down list.
Step 12
Click
Apply
, then click
Yes
to confirm.
Step 13
Click the
Provisioning
>
Optical Chn Optical Connector [n]
>
Parameters
tabs, where n = the
connector number containing the wavelength you are testing. Refer to
, if needed.
Step 14
Scroll to the right until you see the Power Add parameter. Verify that the Power Add value for the tested
port is equal to the output power level of the tunable laser or TXP_MR_2.5G card (measured in
),
+/– 1 dBm.
Step 15
Display the east 32DMX card in card view.
Step 16
Click the
Provisioning > Optical Chn > Parameters
tab. Record the value under the Power parameter
for the wavelength under test.
Step 17
Verify that the power value from
reaches the EastSide.Rx.Power.Add&Drop - Drop Power
se/– 1 dBm. To view this setpoint:
a.
Go to node view and click the
Provisioning > WDM-ANS > Provisioning
tabs.
b.
In the Selector window on the left, expand the
East Side
parameters tree view.
c.
Expand the
RX
category.
d.
Expand the
Power
category, then highlight
Add&Drop - Drop Power
.
e.
View the EastSide.Rx.Power.Add&Drop - Drop Power parameter on the right side of the pane.
If the power values do not match (+/– 2 dBm), remove, clean, and replace each cable on the east side of
the shelf.
See the
“NTP-G115 Clean Fiber Connectors” procedure on page 13-25
Step 18
Display the TXP_MR_2.5G in card view.
