Diagnostics running on the Carrier AT8402

Page 2 - 22 AT8402 CLI Reference Manual

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)
