Chapter 6 Monitoring and Troubleshooting<br />
Monitoring <strong>NSG</strong> <strong>9000</strong>-<strong>6G</strong> Status and Alarms<br />
Alarm Message<br />
Trigger<br />
Device<br />
Redundancy<br />
Description<br />
Solution<br />
Slot<br />
Card Missing* Yes No module is mounted in the slot<br />
and the corresponding RF port is<br />
enabled.<br />
Card Mismatch* No Mismatch between the mounted<br />
module and the sent configuration.<br />
1. Disable the RF port.<br />
2. Mount a module in the slot.<br />
3. Enable the corresponding RF port.<br />
Check configuration or mounted<br />
module.<br />
GbE Port<br />
CRC Error No At least one packet has CRC error Check the switch, fiber, and copper<br />
connections. Check source (input or<br />
output).<br />
ETH Buffer Overflow No Management traffic on the GbE port<br />
exceeds the port’s capacity.<br />
Invalid Input Packet No The payload length of an input UDP<br />
packet is not divisible by 188 bytes<br />
a standard length of an MPEG<br />
packet<br />
Check sources for excessive<br />
management traffic.<br />
Check source.<br />
L2TPv3 Sequence<br />
Error<br />
No<br />
The sequence number of L2TP<br />
frames is not sequential, which<br />
means that some L2TP frames were<br />
dropped in the input.<br />
<br />
<br />
<br />
Check input source.<br />
Check switch.<br />
Check fiber and copper<br />
connections.<br />
Link Down (SFP) Yes Problematic link to the SFP. Verify that the fiber is connected<br />
properly to the SFP<br />
SFP Missing Yes The SFP connector is missing from<br />
the GbE port.<br />
Check that the SFP connector is fully<br />
inserted<br />
GbE Card<br />
GbE Controller<br />
Failure<br />
Yes<br />
PHY ID Error; instable<br />
communication with GbE module.<br />
1. Reset unit.<br />
2. If problem persists, call Customer<br />
Support.<br />
MPEG Buffer<br />
Overflow<br />
No<br />
Buffer is overloaded with too high<br />
bit rate<br />
Reduce bit rate.<br />
MPEG Sync Loss No GbE traffic contains No valid MPEG<br />
data<br />
1. Check source.<br />
2. Check the input cable and replace<br />
if defective.<br />
General HW Failure No GbE module fatal error. Call Customer Support<br />
TS Out<br />
TS Out Overflow No The actual output bit rate exceeds<br />
the configured QAM output bit rate.<br />
Deprovision several services of the<br />
specific output until the alarm clears.<br />
VOD Session<br />
PAT Corrupted* No Invalid PAT Check source.<br />
PAT Missing* No PAT is missing in input signal. Check source<br />
