Chapter 4 Turn Up and Test
Procedure: Check Optical Protection
Continue with the following steps to check optical protection.
Step 11 Set the switchmode for all CLIP modules to automatic:
a.
Record the current switchmode setting for each CLIP module in Table B-10 on page B-6 . You will
need to revert to the original switchmode setting after checking the bit error rate.
b. At the NCB:> prompt, type
conf clip clip_xxx
(where xxx is the serial number of the CLIP
module) and press Enter.
c.
Type
cd dwdm
and press Enter.
d. Type
list value
and press Enter.
e.
Type
switchmode automatic
and press Enter.
f. Type
exit
to quit the CLIP module.
g.
Repeat Steps a – f for all CLIP modules.
Step 12 Remove the fiber jumper cable from the LM A-side INPUT and verify that the Active LED on the A side
goes out and the B side switches from Standby to Active on each CLIP module. Complete Step
12 in
Table B-4 on page B-2 .
Step 13
Reconnect the jumper cable on the A side and verify that the A-side green Standby LED is illuminated
on each CLIP module and that the B-side Active LED remains illuminated. Complete Step
13 in
Table B-4 on page B-2 .
Step 14 Remove the fiber jumper from the LM B-side INPUT and verify that the Active LED on the B side turns
off. Verify that the A side switches from Standby to Active on each CLIP module. Complete Step
14 in
Table B-4 on page B-2 .
Step 15
Reconnect the jumper cable on the B side and verify that the B-side green Standby LED is illuminated
on each CLIP module and that the A-side Active LED remains illuminated. Complete Step
15 in
Table B-4 on page B-2 .
Step 16 Before continuing with the bit error rate testing, complete the following:
•
Verify that all the CLIP modules are still in a daisy chain.
• Verify that the first CLIP module client IN port is connected to the output of the test set, and the last
CLIP module OUT port returns to the test set receive port.
•
Verify that the LM A-side IN port is connected to the LM A-side OUT port, and the LM B-side IN
port is connected to the B-side LM OUT port.
Procedure: Test the Bit Error Rate
Continue with the following steps (as applicable) to test the BER.
Note The maximum number of spans is six for a 3R CLIP, and two for a 2R CLIP.
Step 17 To test bit error rate on unprotected modules, clear all errors on the test set and run BER tests error free
for 15 minutes. Complete Step
17 in Table B-4 on page B-2 .
