Symptoms

On : 44.0.2-64.34.16 version, Eagle 5 - STP (Hardware)

rept-stat-trbl:display=timestamp
the following error occurs.

ERROR
-----------------------
  SEQN UAM AL DEVICE ELEMENT TROUBLE TEXT
  5020.0060 * CDT 15 Minor customer trouble detected
  14-10-14 10:43:28
  5024.0058 *C CDT 3 Critical customer trouble detected
  14-10-14 10:43:28


STEPS
-----------------------
To verify if these are false alarms; from the STP perform the following steps:
1. Confirm that Customer Defined Trouble (CDT) connections are being used.

2. rept-stat-trbl:display=timestamp

2. You will see error 0058 and/or 0060 which should not be present

BUSINESS IMPACT
-----------------------
The issue has the following business impact:
CDT is alarm that can be triggered by any trouble defined by customer like environment etc.

In this case; the customer has not defined any CDT. So the alarms should not appear.
This means they are false alarms and has no impact. However, it impacts over all monitoring as extra alarms are present in Eagle alarms list.

Cause

The customer is not using CDT; hence these are false alarms.
These false alarms can be due to dust on the connectors or can simply be cleared by a MASP switchover.

Solution

Follow the steps below to clear the false alarms:

1. Verify if any pins of the connectors are bent. (no apparent issue in backplane in the pics shared. Need clear closeup pic of J35 and J66 connector)
2. Clean the J35 and J66 connectors with soft blower.
3. Remove & Reinsert the MDAL card
4. Remove Standby GPSM
5. Remove Standby TDM
6. Reinsert Standby TDM
7. Reinsert Standby GPSM
8. Remove Active GPSM
9. Remove Active TDM
10. Reinsert Active TDM
11. Reinsert Active GPSM
12. Boot Both MASP Together in maintenance window
13. Replace the MASP cards with spares ( First Standby and then Active )
14. Take the voltage Measurement in the J35 and J66 using the following procedure:
  a. Connect positive lead to the pin 4 and the negative lead to return (It will be present in FAP)
  b. Connect positive lead to the pin 22 and the negative lead to return (It will be present in FAP)
  c. Connect the positive lead to the pin 4 and the negative lead to the ground ( Connect the negative at any point on the frame for ground)
  d. Connect the positive lead to the pin 22 and the negative lead to the ground (Connect the negative at any point on the frame for ground).

15. Provide Results in following format:
  a. J35 Connector:
    i. Pin 4: ____V for Ground.
    ii. Pin 4: ____V for return.
    iii.Pin 22: ____V for Ground.
    iv. Pin 22: ____V for return.

  b. J66 Connector:
    i. Pin 4: ____V for Ground.
    ii. Pin 4: ____V for return.
    iii.Pin 22: ____V for Ground.
    iv. Pin 22: ____V for return.
16. Provide output of all logs during these sessions and also: rtrv-log:snum=60:enum=62:dir=bkwd:num=100

There is high probability that the false alarms will be cleared by step 13.

If not; then a control shelf replacement may be required. For that: voltage levels mentioned in step 14 & 15 are required to provide data to Hardware Engineering team who will review and decide whether a control shelf replacement is required or not.
