Alcatel-Lucent 1830 PSS-16 - CONTCOM (Inter-Shelf Loss of Communication)

CONTCOM (Inter-shelf loss of communication)
The active master shelf Equipment Controller has determined that the communications
link to a provisioned subtended shelf is down. This alarm may be raised for any of the
following reasons:
• Failure of the intershelf timing and control cable
• Disconnected or missing intershelf timing and control cable
• Subtended shelf loss of power
• Both subtended shelf Equipment Controllers are either failed or missing
For more information, refer to the Alcatel-Lucent 1830 Photonic Service Switch Release

Corrective Action
At the end of each step wait to see if the fault clears. If not, continue with the next step.
...................................................................................................................................................................................................
1
When adding a new subshelf , the rotary dial should be configured with valid shelf ids
(0x02 to 0x18). Check the rotary dial and set it to a valid shelf ID, if applicable.
...................................................................................................................................................................................................
2
Locate the intershelf timing and control cable on the active master shelf controller and
observe the link status LED on the connector.
...................................................................................................................................................................................................
3
If the cable is connected and the link status LED is off, verify that the cable is properly
connected at both ends and reconnect it if necessary.
...................................................................................................................................................................................................
4
If the link status LED remains off when the cable is reconnected, verify that the
subtended shelf is powered on.
...................................................................................................................................................................................................
5
If the subtended shelf is powered on and the cable is connected but the link status LED
remains off, ensure that there is at least one working Equipment Controller in the
subtended shelf (both Activity and Status LEDs should be green). Do not proceed until
there is a working Equipment Controller in the subtended shelf. Once there is at least one
working Equipment Controller in the subtended shelf, replace the intershelf
