Module Diagnostics
The system runs diagnostics tests at power up or when you replace a
module with the power on. Watch for these indicators:
■
During diagnostics tests, the module’s
Error
LED lights yellow.
■
When the diagnostics tests are successfully completed, the
Error
LED
turns off and the port status
L
(Link Status)
LED lights green.
■
If a port status
E
(Error) LED remains yellow, the port is not operational.
■
If the module’s
Error
LED lights yellow, the module has failed a
diagnostic test.
To troubleshoot module failures, see Chapter 7 in the
Getting Started
Guide.
