A-Class Server Selftest Failures/Warnings

A power-on selftest is conducted each time power is applied to the server. Failures that
occur at this point will either prevent selftest from completing or, upon initial completion
of selftest, display warnings on the console.
NOTE Warnings will include a brief description of the fault.
If the selftest fails before any output appears on the console, the three front panel LEDs
(Power, Heartbeat, and LAN connection, shown below) will blink in patterns to identify
which section of selftest failed. To troubleshoot selftest failures using the front panel
LEDs, proceed to the next section.
To troubleshoot selftest failures by chassis code analysis, refer to the Chassis Code
Summary section.

Troubleshooting with Light-Emitting Diode (LED) Interpretation

The LED icons shown above are physically located on the right-hand side of the server,
when you are facing the front. The icon on the far right is a green circle that, under
normal conditions, emits a steady light when server power is on. The middle icon of the
three is an amber heart shape that emits, under normal conditions, a "heartbeat"
blinking light when the server is operating normally. The left-most icon is also amber
and represents the Local Area Network (LAN) signal. Under normal conditions, the LAN
icon blinks irregularly as dictated by LAN signal activity. Additional selftest information
is provided in the sub-sections that follow.
Successful Power-on Selftest.
When power is applied to the server, the green POWER icon will light upon successful
completion of the power supply selftest, which takes approximately 2 seconds. If the
green POWER LED fails to light, check the power source. If the power source is valid,
the problem is usually in the A-Class server power supply. Power supply failures are
repaired by replacing the A-Class Exchange Base Unit (EBU). Refer to the Replacing an
A-Class Server Exchange Base Unit (EBU) section. After the green POWER icon comes
on, both the amber HEARTBEAT and amber LAN ACTIVITY icons will momentarily
light and go out. When selftest is complete, the firmware Main Menu screen will display
on the console, and the green POWER icon will emit a steady light. LED icon states will
appear as shown below:
The following table shows how to interpret front panel LED blinking codes when selftest
has failed and the firmware Main Menu screen is inaccessible. During the conditions
shown in this table, the green POWER icon is ON.
