Escala BL460 - Problem Determination and Service Guide
•
Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
•
See Chapter 3 , “ Parts listing ,” on page 197 to determine which components are CRUs and which components are
FRUs.
• If an action step is preceded by “(Trained service technician only),” that step must be performed only by a trained
service technician.
Symptom Action
The blade server does
not turn on.
1. Make sure that:
a. The power LED on the front of the Bull Blade Chassis - Enterprise is on.
b. The LEDs on all the Chassis power modules are on.
c. The blade server is in a blade bay that is supported by the power modules installed in
the Bull Blade Chassis - Enterprise.
d. The power-on LED on the blade server control panel is blinking slowly.
•
If the power LED is flashing rapidly instead of blinking slowly, and
continues to flash rapidly, the blade server is not communicating with the
management module; reseat the blade server by following these
procedures:
i. “ Removing the management card ”, on page 216
ii. “ Installing the management card ”, on page 217
If reseating the blade server or the management card does not resolve
the problem, go to step 3.
•
If the power LED is off instead of flashing slowly, 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 management module Web
interface to verify), or the blade server was instructed through the management module Web
interface to start.
2. 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.
3. Try another blade server in the blade bay; if it works, replace the faulty blade server.
4. See “
Solving undetermined problems ” on page 194 .
The blade server turns
off for no apparent
reason
1. Make sure that each blade bay has a blade server, expansion unit, or blade filler correctly
installed. If these components are missing or incorrectly installed, an over-temperature
condition might result in shutdown.
2. If a microprocessor error LED is lit, replace the system-board and chassis assembly.
The blade server does
not turn off.
1. Verify whether you are using an ACPI or non-ACPI operating system. If you are using a non-
ACPI operating system:
a. Press Ctrl+Alt+Delete.
b. Turn off the system by holding the power-control button for 4 seconds.
c. If the blade server fails during POST and the power-control button does not work,
remove the blade server from the bay and reseat it.
2. If the problem remains or if you are using an ACPI-aware operating system, suspect the
system-board and chassis assembly.
