BladeCenter HX5 Blade ServerProblem Determination and Service Guide
Action
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.
Action
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.
2. Check the function of the shared BladeCenter chassis resources (see "Solving
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.
4. (Trained service technician only) Replace the system-board assembly. See
"Removing the system-board assembly - BladeCenter HX5" on page 140 and
"Installing the system-board assembly - BladeCenter HX5" on page 142.
