Description
This test will verify the BCM internal memory banks.
Failure impact
•
BCM-00010004 diagnostic code results of failure of one or more BCM internal
memories. The impact is complete loss of Ethernet functionality.
•
BCM-00010005 diagnostic code results of failure loading the BCM drivers

BCM_LOOPBACK
Internal loopback test.
Test group:
Diagnostics
Test case:
bcm
Test procedure: BCM_LOOPBACK
Test host:
Carrier
Test IC:
quickturn
Test mode:
normal
Diagnostic code: BCM-00010005, BCM-00010101 - BCM-00010114
Description
The Ethernet interfaces are tested by establising an PHY loopback internal to the
Ethernet PHYs. It will send test patterns and check correct reception of the test-patterns
for each Ethernet interface. The loopback is either through the BCM internal SERDES
PHY for SERDES based links or through the external 1000BaseT PHY.
