Procedure 5-3: Address VLNC40/42/42B, VLNC60/61/62, or VLNC64 circuit pack related failures
Overview
Use this procedure to address the following VLNC40/42/42B, VLNC60/61/62/64 circuit pack related failures:
-
shelf fan failure
-
circuit pack failure
-
pluggable transmission module failure
-
incoming signal failure
If the Alcatel-Lucent 1850 TSS-5 shelf is equipped with a VLNC40/42/42B Ethernet Aggregator, VLNC60/61/62 Circuit Emulator, and/or VLNC64 Circuit Emulation Mini-Hub circuit pack, service-affecting incoming signal failures and equipment failures are reported using circuit pack faceplate LED indicators and Simple Network Management Protocol (SNMP) traps.
When in T-MPLS mode, the VLNC40/42/42B Ethernet Aggregator circuit pack supports four miscellaneous discrete inputs (MDIs) and one miscellaneous discrete output (MDO). These are configurable via the WebGUI, and reported via the WebGUI and TL1. The MDO implements a control point output (CPO) that can either be manually operated via the WebGUI, or may be provisioned to operate automatically based on a provisioned alarm condition type and AID
To address SNMP traps, refer to Procedure 5-4: Address VLNC40/42/42B circuit pack SNMP traps, Procedure 5-6: Address VLNC60/61/62 circuit pack SNMP traps, and/or Procedure 5-7: Address VLNC64 circuit pack SNMP traps.
Before you begin
Prior to performing this procedure:
-
Refer to Before you begin and Required equipment in this chapter.
-
Refer to Electrostatic discharge in Chapter 1, Safety.
Steps
Complete the following steps to address a VLNC40/42/42B, VLNC60/61/62, or VLNC64 circuit pack related failure.
1 |
Observe the green PWR ON LEDs and red FAN FAULT LED on the fan unit. Verify that the fan unit is working properly. If required, replace the fan unit. Reference: Procedure 5-19: Clear "fan shelf failed" or "hardware failure" alarm | ||||||||||||||
2 |
Observe the affected circuit pack faceplate LEDs.

3 |
Disconnecting cables and/or replacing circuit packs may disrupt service. Before taking action, determine the extent of service disruption caused by disconnecting cables or replacing a circuit pack. Then, perform the action(s) deemed appropriate in light of the traffic being carried and the nature of the failure. Important! A lighted circuit pack faceplate FAULT LED indicates a circuit pack failure. Perform the following:

4 |
Disconnecting cables and/or replacing circuit packs may disrupt service. Before taking action, determine the extent of service disruption caused by disconnecting cables or replacing a circuit pack. Then, perform the action(s) deemed appropriate in light of the traffic being carried and the nature of the failure. If the circuit pack FAULT LED is still lighted (solid), replace the circuit pack. Reference: Procedure 6-5: Replace VLNC4x or VLNC6x circuit pack | ||||||||||||||
5 |
If the circuit pack FAULT LED is still lighted (solid), contact your next level of support. STOP! End of Procedure. | ||||||||||||||
6 |
Important! A flashing circuit pack FAULT LED and a lighted (solid) port LED indicate a pluggable transmission module failure. Using office records verify that the pluggable transmission module is required in the socket.
Reference: Procedure 6-6: Replace pluggable transmission module | ||||||||||||||
7 |
If the circuit pack FAULT LED is still flashing and the port LED is lighted (solid), contact your next level of support. STOP! End of Procedure. | ||||||||||||||
8 |
Important! A flashing circuit pack FAULT LED and a flashing port LED indicate an incoming signal failure. On the VLNC60/61/62 circuit pack, a flashing circuit pack FAULT LED may also indicate an incoming signal failure on the DS1 ports. An incoming signal failure on the DS1 ports is indicated only when an encapsulation (satop or ppp) is configured. Consult and follow local procedures to isolate and clear the trouble. | ||||||||||||||

If the circuit pack FAULT LED and the port LED are still flashing, contact your next level of support. STOP! End of Procedure. End of steps |
