1. Make sure that the light path diagnostics LED is lit, to ensure that there is
enough power in the blade server to light the rest of the LEDs. View the
media tray select LED. If it is lit, there is sufficient power in the blade
server to light the rest of the LEDs. If it is not lit, install the blade server in
a chassis for approximately 2 hours to charge the blade server (the blade
server does not have to be powered on).
See “Viewing the light path diagnostics LEDs” on page 203.
2. Check the IMM event log for information about an error that is not
represented by a light path diagnostics LED. See “IMM error codes in
AMM” on page 162.
