Page: 272 / 313

• See “ Parts listing - BladeCenter HX5 ” on page 57 to determine which components are CRUs and which
components are FRUs.
• 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. Check the AMM and IMM event logs for an error message (see “Event logs” on
page 147).
2. Make sure that:
• When the blade server is turned on, air is flowing from the rear of the
BladeCenter chassis at the blower grille. If there is no airflow, the blower is
not working. This causes the blade server to overheat and shut down.
• The storage drives are configured correctly.
3. See “Solving undetermined problems” on page 274.
Keyboard or mouse problems
Use this information to look up and resolve keyboard or mouse problems.
IBM continually updates the support website with tips and techniques that you can use to resolve any

All keyboard and mouse
problems.
1. Make sure that the keyboard/video/mouse 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.

shared BladeCenter resource problems” on page 269).
3. Make sure that:
• The device drivers are installed correctly. See “Updating firmware and device
drivers” on page 30.
• 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
chassis. Some operating systems allow you to select the type of keyboard
and mouse during installation of the operating system. If so, select USB.
