Diagnostic tests can also be run manually to test and troubleshoot the hardware and the firmware, including internal
connections and circuitry, transceivers, and port cables. However, diagnostic tests are generally intended for use by
support personnel.
NOTE
Error messages do not necessarily indicate that the device requires maintenance.
Each diagnostic test can be implemented by entering the related command through a telnet or serial session. For a list of
diagnostic tests and commands, refer to the Brocade Fabric OS Administration Guide.
All diagnostic tests are run at all supported link speeds. They might temporarily lock the transmit and receive speeds to
a specific speed. Some diagnostic tests require interconnecting the ports to each other or using loopback plugs. If ports
are interconnected, the media (cables and transceivers) at each end of the connection must be of the same type. For
example, short-wavelength media must be connected to short-wavelength media, and likewise, long-wavelength media
must be connected to long-wavelength media and copper media must be connected to copper media.
For more information about diagnostic tests and how to run them, refer to the Brocade Fabric OS Administration Guide
and the Brocade Fabric OS Command Reference Manual. For information about system error messages (errShow or
errDump) , refer to the Brocade Fabric OS Troubleshooting and Diagnostics Guide.
