1. Go to http://www.ibm.com/pc/support/.
2. Select Servers from the list on the left side of the window.
3. Select Downloadable files from the list on the left side of the window.

page.
Use the light path diagnostics feature to identify system errors quickly. On the
BladeCenter T unit, the light path diagnostics feature consists of the LEDs on the
front of the BladeCenter T unit and on the front of the modules and blade
servers.
