SBXL52: Hardware Maintenance Manual and Troubleshooting Guide
The blade server does not turn
on.
1.
Verify that:
a.
The power LED on the front of the SBCE unit is on.
b.
The LEDs on all the SBCE power modules are on.
c.
If the blade server or attached storage expansion unit is in blade bay 7-14,
power modules are in power bays 1, 2, 3 and 4.
d.
The power-on LED on the blade server control panel is blinking slowly.
•
If the power LED is blinking rapidly and continues to do so, the blade
server is not communicating with the management module; reseat the
blade server, then go to step 3
•
If the power LED is off, the blade bay is not receiving power, the blade
server is defective, or the LED information panel is loose or defective.
e.
Local power control for the blade server is enabled (use the SBCE
management module Web interface to verify), or the blade server was
instructed through the management module (Web interface) to turn on.
2.
If you just installed an option in the blade server, remove it, and restart the
blade server. If the blade server now turns on, you may have installed more
options than the power to that blade bay supports.
3.
Try another blade server in the blade bay; if it works, replace the faulty blade
server.
4.
See “Undetermined problems” on page 100.
The blade server does not turn
on and the following conditions
are present:
1.
The amber system error
LED on the Blade Center
unit’s system LED panel is
lit;
2.
The amber blade error
LED on the blade server’s
LED panel is lit; and
3.
The system error log
contains the message
"CPUs mismatched".
•
The microprocessor with the lowest feature set
must be used as the Bootstrap
Processor (microprocessor 1 in location U66; see “System board illustration” on
page 29).
Move the microprocessor in location U66 to location U70, and move
the microprocessor in location U70 to location U66.
The blade server turns off for
no apparent reason
1.
Verify that all blade bays have a blade server, expansion unit, or filler
blade properly installed.
If these components are missing or improperly
installed, an over-temperature condition may result in shutdown.
2.
If microprocessor LED is illuminated, replace the microprocessor.
NOTE
See “System” on page 104 to determine which components should be replaced by a field service
technician.
