BladeCenter HS23E Type 8038 and 8039: Problem Determination and Service Guide
Action
1. Check the function of the shared BladeCenter unit resources. See "Solving
shared BladeCenter resource problems" on page 222.
2. Make sure that the power LED on the blade server control panel is flashing
slowly. See "Blade server controls and LEDs" on page 9.
v 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 unit" on
page 49 and "Installing the blade server in a BladeCenter unit" on page 50.
v If the power LED is off, the blade server bay is not receiving power, the
blade server is defective, or the LED information panel is loose or defective.
See "Removing the blade server from the BladeCenter unit" on page 49 and
"Installing the blade server in a BladeCenter unit" on page 50.
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 log of the corresponding blade
server for an error that is preventing the blade server from turning on. See
"Event logs" on page 96.
5. Reseat the blade server. See "Removing the blade server from the BladeCenter
unit" on page 49 and "Installing the blade server in a BladeCenter unit" on
page 50.
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. If you tried another blade server in the blade server bay when you check the
function of the shared BladeCenter unit resources and the other blade server
worked, complete the following tasks on the blade server that you removed:
a. If an optional expansion unit is installed, reseat it. See "Removing an
optional expansion unit" on page 79 and "Installing an optional expansion
unit" on page 80.
b. Replace the following components one at a time, in the order shown,
restarting the blade server each time:
1) Optional expansion unit (if one is installed). See "Removing an optional
expansion unit" on page 79 and "Installing an optional expansion unit"
on page 80.
2) (Trained technician only) System-board assembly. See "Removing the
system-board assembly" on page 90 and "Installing the system-board
assembly" on page 91.
8. See "Solving undetermined problems" on page 226.
1. Check the function of the shared BladeCenter unit resources. See "Solving
shared BladeCenter resource problems" on page 222.
2. (Trained technician only) If the microprocessor error LED is lit, replace the
microprocessor. See "Removing a microprocessor and heat sink" on page 81
and "Installing a microprocessor and heat sink" on page 84.
3. (Trained technician only) Replace the system-board assembly. See "Removing
the system-board assembly" on page 90 and "Installing the system-board
assembly" on page 91.
