Note the following about this output:
v The absent state simply reflects that the blade slot is empty.
v The sensor index is mainly for support use.
v Multiple sensors are commonly averaged to determine thresholds used for managing fan speeds or for
determining a high temperature condition that may require that the blade be shut off.
Running diagnostic tests
Diagnostic tests are automatically run during POST to check the status of the device. 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: 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 Fabric OS Administrator's 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 with long wavelength media and copper media.
