Note: When you press the power button, the media tray select button/LED should also be lit if
the capacitor is charged. If the media tray select button/LED is lit but no LEDs on the system
board are lit, there are no hardware-related issues on the blade server. If the media tray select
LED fails to light, install the blade server in a chassis for approximately 2 hours to enable the
light path diagnostics panel to charge.
See "System-board LEDs - BladeCenter HX5" on page 15 for the location of the LEDs on the
system board. See "Light path diagnostics LEDs" on page 207 for information about resolving
those LEDs.
Step 4.
View the LEDs displayed on the access panel.
There are two types of access panels available with the BladeCenter HX5, depending on whether
