Operating the SAN Director 2/128 Diagnostics Diagnostic tests are automatically run during POST to check the status of the switch. Any error messages generated during POST are sent to the error logs and to the serial console, if connected. 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: Diagnostic error messages do not necessarily indicate that the switch 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 Fabric OS Procedures Guide. All diagnostic tests are run at link speeds of both 1 and 2 Gb/sec. 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 with long wavelength media and copper media. For more information about diagnostic tests and how to run them, refer to the HP StorageWorks Fabric OS 4.2.x Procedures User Guide. 100 SAN Director 2/128 Installation Guide
