If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
A problem occurs only
occasionally and is difficult to
diagnose.
1. Make sure that:
v
When the blade server is turned on, air is flowing from the rear of the
BladeCenter unit at the blower grille. If there is no airflow, the blower is not
working. This causes the blade server to overheat and shut down.
v
The SAS hard disk drives are configured correctly (see “Using the LSI Logic
Configuration Utility program” on page 18).
2.
Check the BMC log (see “Error logs” on page 72).
Keyboard or mouse problems
The keyboard and mouse are shared BladeCenter unit resources. First, make sure
that the keyboard and mouse are assigned to the blade server; then, see the
following table and “Solving shared BladeCenter resource problems” on page 160.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
All keyboard and mouse
problems.
1. Make sure that the KVM select button LED on the front of the blade server is
lit, indicating that the blade server is connected to the shared keyboard and
mouse (see “Blade server controls and LEDs” on page 3).
2. Check the function of the shared BladeCenter unit resources (see “Solving
shared BladeCenter resource problems” on page 160).
3. Make sure that:
v The keyboard and mouse work with another blade server.
v The device drivers are installed correctly.
v
The keyboard and mouse are recognized as USB, not PS/2, devices by the
blade server. Although the keyboard and mouse might be a PS/2-style
devices, communication with them is through USB in the BladeCenter unit.
Some operating systems enable you to select the type of keyboard and
mouse during installation of the operating system. If this is the case, select
USB.
4. (Trained service technician only) Replace the system-board assembly (see
“Removing the system-board assembly” on page 62 and “Installing the
system-board assembly” on page 62).
