Chapter 2. Diagnostics and troubleshooting
This chapter provides basic troubleshooting information to help you solve some
common problems that might occur while setting up your blade server.
A problem with the BladeCenter QS20 can relate to either the BladeCenter QS20 or
the BladeCenter unit.
v A blade-server problem exists if the BladeCenter unit contains more than one
blade server and only one of the blade servers has the symptom.
v
If all of the blade servers have the same symptom, then the problem relates to
the BladeCenter unit. For more information, see the IBM BladeCenter (Type
8677) Hardware Maintenance Manual and Troubleshooting Guide .
Note:
– The BladeCenter QS20 is supported in the 8677 BladeCenter chassis
only.
– You can only have BladeCenter QS20 blades in a chassis, you cannot
put other blade server types in the same chassis as a BladeCenter
QS20.
If you install the blade server in the BladeCenter unit and the blade server does not
start, perform the following actions:
v
Make sure that the BladeCenter unit is correctly connected to a power source.
v
Reseat the blade server in the BladeCenter unit.
v
If the power-on LED is flashing slowly, turn on the blade server (see “Turning on
the blade server” on page 5).
v
If you have just added a new optional device or component, make sure that it is
correctly installed and compatible with the blade server and its components. If
the device or component is not compatible, remove it from the blade server,
reinstall the blade server in the BladeCenter unit, and then restart the blade
server.
