BladeCenter HS20 Type 7981: Installation and User's Guide
Suggested action
Make sure that:
v The option is designed for the blade server. See the "Server Support" flowchart on
the cover for information about obtaining ServerProven compatibility information
from the World Wide Web.
v You followed the installation instructions that come with the option.
v The option is installed correctly.
v You have not loosened any other installed options or cables.
If the problem remains, call for service.
Make sure that all of the option hardware and cable connections are secure.
If the option comes with its own test instructions, use those instructions to test the
option.
If the problem remains, call for service.
Suggested action
1. Make sure that:
a. The power LED on the front of the BladeCenter unit is lit.
b. The LEDs on all the power modules are lit.
c. If the blade server or attached storage expansion unit is in blade bays 7
through 14 (in the BladeCenter unit) or blade bays 5 through 8 (in the
BladeCenter T unit), power modules are in all four power bays.
d. The power LED on the blade server control panel is flashing slowly.
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 and go to step 3.
v If the power LED is off, either 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 or IBM Director) to
turn on.
Note: For more information about IBM Director, see the IBM Director
documentation on the IBM Director CD.
2. If you just installed an expansion card in the blade server, remove it and restart
the blade server. If the blade server now turns on, troubleshoot the option (see
the documentation that comes with the option for information).
3. Try another blade server in the blade bay; if it works, replace the faulty blade
server.
4. If the problem remains, call for service.
