b.
Wait 90 seconds then, in node view, click the
Alarms
tab. If the LOS alarm on the east OSC-CSM
card clears, continue with
. If not, continue with Step
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
Yes
.
i.
In node view, click the
Alarms
tab. If the LOS alarm on the east OSC-CSM card clears, continue
with
. If not, replace the OSC-CSM card.
Step 21
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 under test, then continue with
.
Step 22
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 23
Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the west OSC-CSM
LINE RX port using a 10-dB bulk attenuator.
Caution
Failure to use proper attenuation might damage equipment.
Step 24
If an OPT-PRE card is installed on the west side, complete the
Amplifier Laser and Power” task on page 4-41
. If not, continue with
.
Step 25
Display the east OSC-CSM card in card view.
Step 26
Click the
Provisioning > Optical Line > Parameters
tabs. Locate the Port 3 Power value. Verify that
the value is higher than –30 dBm. If the power value is not higher than –30 dBm, check your connections
and clean the fibers using the
“NTP-G115 Clean Fiber Connectors” procedure on page 13-25
. If this does
not change the power value, consult your next level of support.
Step 27
If an OPT-PRE is installed on the east side of the shelf, complete the
Amplifier Laser and Power” task on page 4-41
for the east OPT-PRE amplifier. If not, continue with
Step 28
Display the west OSC-CSM card in card view.
Step 29
Click the
Provisioning > Optical Line > Parameters
tabs and locate the Power value for Port 2. Verify
that the value is higher than –30 dBm. If the power value is not higher than –30 dBm, check your
connections and clean the fibers using the
“NTP-G115 Clean Fiber Connectors” procedure on
. If this does not change the power value, consult your next level of support.
Step 30
Disconnect the TXP or tunable laser from the west OSC-CSM card.
Step 31
Remove the loopback created on the east OSC-CSM card in
.
Step 32
Delete both OSC channels. See the
“DLP-G186 Delete an OSC Termination” task on page 10-41
