System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Packet Interface Private Loop-Around test for
example, you may also clear errors generated from other tests in the testing
sequence.
Notes:
a. This test only runs on an active IPSI circuit pack’s Packet Interface.
b. This test only runs on a standby IPSI circuit pack’s Packet Interface.
Memory Checksum Test (#884)
This test involves sending a message to the Packet Interface circuit to run private
non-destructive memory checksum tests on the firmware text residing in Boot
PROM and FLASH memory. If the test fails during background testing, the IPSI
circuit pack remains operational until an executed reset. Then, the initialization
firmware fails and puts the IPSI circuit pack in an out-of-service state.
