Test mode: normal
Diagnostic code: PLX-00070005 PLX-00070008 PLX-000703nn PLX-000704nn
Description
This tests reads the e-keying status of all AMC PCI Express ports. If an AMC PCI
Express port is enabled via e-keying, it checks for the LANEGOOD signals of the
associated PLX port and reports an error if no LANEGOOD status is detected.
Failure Impact
• PLX-00070005 diagnostic code results from failure to read PLX LANEGOOD sta-
tus. Impact is failure of IPMC subsystem.
• PLX-00070008 diagnostic code results from PCIe is in reset. The PCIe is going to
reset if the upstream port is deactivated. Impact is failure of PCI express infrastruc-
ture on all ports.
• PLX-000703nn diagnostic codes results if e-keying status is enabled for PLX port
nn but no LANEGOOD status bit is detected. This occurs if a processor-AMC is
inserted in an AMC bay configured as downstream or a GE-AMC is inserted in an
AMC bay configured as upstream or PCIe infrastructure on AMC fails. Impact is
failure of PCI express infrastructure on port nn.
• PLX-000704nn diagnostic code results if e-keying status is enabled for PLX port
nn but LANEGOOD status is incorrect. Impact is failure of PCI express infrastruc-
ture on port nn.

Port table
For the diagnostic codes PLX-000703nn or PLX-000704nn the port nn which fails is
indicated. The following relation is valid
•
port 0 : AMC-B4
• port 1 : AMC-B3
• port 2 : Update Channel
• port 8 : AMC-B2
• port 9 : AMC-B1
• port 10 : SAS (no ekeying, not checked)
