For example:
A blade server error has occurred and you have noted that the blade server blade-error LED is lit on
the blade server control panel. You then:
1. Remove the blade server from the SBCE unit.
2. Place the blade server on a flat, static-protective surface.
3. Remove the cover from the blade server.
4. Press and hold the light path diagnostics button to relight the LEDs that were lit before you
removed the blade server from the SBCE unit. The LEDs will remain lit for as long as you press
the button, to a maximum of 25 seconds.
NOTE
Power is available to relight the light path diagnostics LEDs for a short period of time after
the blade server is removed from the SBCE unit. 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
SBCE unit) by pressing the light path diagnostics button. The light path diagnostics power
present LED (CR111) lights 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
does not light 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.
Use the table at "Light Path Diagnostics" on page 65 to help determine the cause of the error and the
action you should take.
Memory errors
If a memory problem occurs, take the following actions before replacing a DIMM:
1. Reseat both DIMMs in the bank.
2. Check for a memory type mismatch in the bank.
3. Run the diagnostic programs.
For more information about memory, see "Installing memory modules" on page 23.
