Microprocessor problems
Identify microprocessor problem symptoms and the corrective actions to take.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v
See Chapter 3, “Parts listing, type 7891,” on page 225 to determine which components are CRUs and which
components are FRUs.
v
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 will not boot
or a checkpoint or firmware
error code is logged in the
management-module event log
(the startup microprocessor is
not working correctly)
1. If a checkpoint or firmware error was logged in the Advanced Management
Module event log, correct that error.
2. If no error was logged, restart the blade server and check the management
module event log again for error codes.
3. Replace the system-board
Network connection problems
Identify network connection problem symptoms and the corrective actions to take.
v
Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 3, “Parts listing, type 7891,” on page 225 to determine which components are CRUs and which
components are FRUs.
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
One or more blade servers are
unable to communicate with
the network.
1. Verify that the I/O module is a switch or pass thru module. Ppass thru
modules require an upstream switch for network traffic to pass.
2.
Ensure the correct device drivers are installed.
3. Verify that the optional I/O expansion cards are correctly installed and
configured, see “Removing and installing an I/O expansion card” on page 253
PCI expansion card (PIOCARD) problem isolation procedure
The hardware that controls PCI adapters and PCI card slots detected an error. The direct select address
(DSA) portion of the system reference code (SRC) identifies the location code of the failing component.
