System Checkout; Checkpoint Codes - IBM eServer BladeCenter JS20 Installation And User Manual

System checkout

If your system fails to start after installation or an error occurs while running,
perform the following steps:
1. Visually check the blade server system board for any lit external LEDs.
2. Reinstall the blade server in the same slot of the BladeCenter unit.
3. To test the blade server, turn on the blade server and start a Serial over LAN
4. Observe the progress codes in the SOL window and record any power-on
5. Review the BladeCenter management-module event log and Linux Syslog to

Checkpoint codes

The power-on self-test (POST) firmware checkpoints (progress codes) indicate the
detection of a problem if the server stops on a checkpoint during the startup
process.
v A four-digit code indicates successful completion of POST when the server does
v A result other than a four-digit code indicates that POST might have detected a
Checkpoints display in the system console from the time that ac power is connected
to the system until the operating system login prompt is displayed after a successful
operating system startup. These checkpoints have the following forms:
Dxxx, Exxx

a. Turn off the server.
b. Remove the blade server from the BladeCenter unit.
c. Open the blade server and press and hold the light path diagnostics button.
See "System-board LEDs" on page 10 for the location of the light path
diagnostics button.
d. Perform the steps in "Identifying problems using the light path diagnostics"
on page 92 to identify lit error LEDs on the blade server.
1) If any LEDs light, see "Light path diagnostics table" on page 93.
2) If there is no error LED lit, proceed to the next step.

problem. Error messages also appear during startup if POST detects a
hardware-configuration problem. The last POST firmware checkpoint code posted
is the most likely failure.
Dxxx and Exxx checkpoints indicate that a system processor is in
control and is initializing the system resources. Control passes to
the operating system when E105 displays on the operator panel
display. Location code information might also display on the
operator panel during this time.
These codes range from Dxxx to EFFF.
If a fault is detected, an 8-digit error code is displayed in the
BladeCenter management-module event log. A location code might
be displayed at the same time on the second line.
