057
Component replaced or reseated.
– Remove processor node from service position.
– Reconnect all cables at rear of the processor node.
– Put circuit breakers at the front of processor node in the On (‘1’) position.
– Check error log or SRN.
Does the problem still exist?
Yes No
058
Problem resolved.
– Go to “MAP 0570: End of Call” on page 1-357.
059
– Put circuit breakers at the front of the processor node in the Off (‘0’) position.
– Reinstall the previously removed component.
– Go to Step 056 on page 1-166 to service next highest priority component.
060
Memory protection error: “memoryProtect”
This fault is normally generated only when invalid memory cards are installed in the processor node.
