12 NovaScale Blade 2320 Installation and User’s Guide
Using Light Path Diagnostics to Troubleshoot the System Board
You have to remove the blade server from the NovaScale Blade Chassis, open the cover,
and press the light path diagnostics switch (SW4) to light any error LEDs that were turned
on during processing. These LEDs can be used to help troubleshoot system-board
component problems. See the illustrations in this section, Table 2, "System Board LEDs"
on page 13 and Table 3, "Light Path Diagnostics Panel LEDs" on page 13 for information
about locating light path diagnostics LEDs and what to do if there is an error LED lit.
“Light Path Diagnostics LEDs” on page 51 provides more information about the light path
diagnostics LED locations, settings, and error solutions. Refer to these illustrations and
tables when solving problems with the blade server.
Power is available to relight the light path diagnostics LEDs for a small period of time
after the blade server is removed from the NovaScale Blade Chassis. During that period of
time, you can relight the light path diagnostics LEDs for a maximum of 25 seconds (or
less, depending on the number of LEDs that are lit and the length of time the blade server
is removed from the NovaScale Blade Chassis) by pressing the light path diagnostics
button. The light path diagnostics power present LED (CR111) is lit when the light path
diagnostics button is pressed if power is available to relight the blade-error LEDs. If the
light path diagnostics power present LED (CR111) is not lit when the light path
diagnostics button is pressed, no power is available to light the blade-error LEDs, and they
will be unable to provide any diagnostic information.
