NOTE: These register names are the most probable to be displayed in the port register test error message, however there
are other possible register names.
Probable cause: A port register test error message is probably caused by:
— Failure of the G_Port and FL_Port ASIC
— Failure of the interface module — Interface module connector
Action: Replace the switch
ramTest
Figure 7-18 shows the ramTest command, which is used to check microprocessor random-access memory
(RAM). The switch ships with 2 megabytes (MB) of RAM. This test validates proper memory function.
Figure 7-18. ramTest Command Example
If the test does not find an error, there is no output. If an error is found, the following message is displayed:
DIAG-MEMORY, O
Memory Error-address OxXXXX is OxXXXX sb OxXXXX
Probable cause: CPU board failure
Action: Replace the switch
rdramTest
Figure 7-19 shows the rdramTest command, which is used to check the memory on the FL_Port interface
cards. A diagnostic pattern is written and read from memory to ensure all RDRAM memory is properly
functioning.
This command may not be executed on an operational switch. Before issuing rdramTest, disable the switch
using the switchDisable command.
