Symptom Action
The blade server does not turn
on.
1.
Check the function of the shared BladeCenter unit resources (see “Solving
shared BladeCenter resource problems” on page 160).
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 3).
v
If the power LED is flashing rapidly and continues to do so, the blade server
is not communicating with the management-module; reseat the blade server
(see “Removing the blade server from a BladeCenter unit” on page 27 and
“Installing the blade server in a BladeCenter unit” on page 28) and go to
step 6
v
If the power LED is off, the blade bay is not receiving power, the blade
server is defective, or the control panel is loose or defective.
3.
Check the power-management policies in the operating system for the blade
server.
4. Reseat the blade server (see “Removing the blade server from a BladeCenter
unit” on page 27 and “Installing the blade server in a BladeCenter unit” on
page 28).
5. 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 bay supports.
6. If you tried another blade server in the blade bay when you checked 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.
Reseat the following components:
1)
MPE unit, if one is installed (see “Removing an expansion unit” on
page 31 and “Installing an expansion unit” on page 32)
2) Control panel cable (see “Removing the bezel assembly” on page 33
and “Installing the bezel assembly” on page 34)
b. Replace the following components one at a time, in the order shown,
restarting the blade server each time:
1) Blade server bezel assembly (see “Removing the bezel assembly” on
page 33 and “Installing the bezel assembly” on page 34)
2) (Trained service technician only) MPE board assembly, if one is installed
(see “Removing the system-board assembly” on page 62 and “Installing
the system-board assembly” on page 62)
3) (Trained service technician only) System-board assembly (see
“Removing the system-board assembly” on page 62 and “Installing the
system-board assembly” on page 62)
7. See “Solving undetermined problems” on page 164.
