Brocade ICX 6650 maintenance
The ICX 6650 is designed for high availability and low failure; it does not require any regular
physical maintenance. Supported transceivers and diagnostic tests are described in the following
sections.
Diagnostic tests and monitoring
Brocade Network OS includes diagnostic tests to help you troubleshoot the hardware. System
diagnostic software is designed to fulfill the purpose of off-line diagnostics. In off-line diagnostics,
you have to turn ON/OFF the diagnostic flags to execute diagnostic tests during the next boot-up.
The CLI commands for system diagnostic tests are dm diag and dm alt-diag. These diagnostic tests
verify all available hardware components including:
•I2C devices
•EEPROMS
•CPU packet
•Test MAC alignment
•Line rate
During system diagnostic testing, the system is completely under the control of the diagnostic
software. All hardware components are verified, and results are displayed on the console. In cases
where a failure is detected, results and corrective actions will be displayed. After the system
diagnostic testing is complete, the system exits from the diagnostic mode and reloads the system
for normal operation.
System diagnostic testing runs at link speeds 10 Gbps and 40 Gbps (QSFP ports) depending on the
speed of the link being tested and the type of port.
