BladeCenter HX5 Blade ServerProblem Determination and Service Guide
Action
1. Reseat the control-panel connector. See "Blade server controls and LEDs" on
page 7.
2. (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.
1. Check the function of the shared BladeCenter chassis resources. See "Solving
shared BladeCenter resource problems" on page 269.
2. Make sure that the power-on LED on the blade server control panel is flashing
slowly. See "Blade server controls and LEDs" on page 7.
• If the power LED is flashing rapidly and continues to do so, the blade server
is not communicating with the advanced management module; reseat the
blade server. See "Removing the blade server from the BladeCenter chassis"
on page 66 and "Installing a blade server in a BladeCenter chassis" on page
67.
• If the power LED is off, the blade server bay is not receiving power, the blade
server is defective, or the operator control panel is loose or defective. See
"Removing the blade server from the BladeCenter chassis" on page 66 and
"Installing a blade server in a BladeCenter chassis" on page 67. In addition,
see "Removing the control panel" on page 124 and "Installing the control
panel" on page 126.
3. Check the power-management policies in the operating system for the blade
server. See the Advanced Management Module User's Guide for more
information.
4. Check the advanced management module event log of the corresponding blade
server for an error that is preventing the blade server from turning on. See
"Event logs" on page 147.
5. Reseat the blade server. See "Removing the blade server from the BladeCenter
chassis" on page 66 and "Installing a blade server in a BladeCenter chassis" on
page 67.
6. If you just installed a device in the blade server, remove it and restart the blade
server. If the blade server now starts, you might have installed more devices
than the power to that blade server bay supports.
7. (Trained service technician only) If you tried another blade server in the blade
server bay when you check the function of the shared BladeCenter chassis
resources and the other blade server worked, 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.
8. See "Solving undetermined problems" on page 274.
