Undetermined problems ✏ NOTE When troubleshooting a problem with the blade server, it must be determined whether the problem is a blade server problem or a problem with the SBCE unit. • If the SBCE unit contains more than one blade server and only one of the blade servers exhibits the problem, it is likely that it is a blade server problem. • If all of the blade servers exhibit the same symptom, it is probably a SBCE unit problem; for more information, see the Intel Server System SBCE Hardware Maintenance Manual. Use the information in this section if the diagnostic tests did not identify the failure, the devices list is incorrect, or the system is inoperative. Notes: 1. Damaged data in CMOS can cause undetermined problems. To reset the CMOS, remove the battery for 15 minutes, and then reinstall the battery. 2. Damaged data in BIOS code can cause undetermined problems. • Flash the system with the latest BIOS code. • If the system appears inoperative, recover the BIOS (see "Recovering the BIOS code" on page 25). Check the LEDs on all the power supplies of the SBCE unit where the blade server is installed. If the LEDs indicate the power supplies are working correctly, and reseating the blade server does not correct the problem, complete the following steps: 1. Check that the front panel is connected to the system board. 2. If no LEDs on the front panel are working, replace the front panel; then, try to power up the blade server from the SBCE web interface (see the SBCE documentation for more information). 3. Turn off the blade server. 4. Remove the blade server and remove the cover. 5. Remove or disconnect the following devices (one at a time) until you find the failure (reinstall, turn on and reconfigure the blade server each time): • I/O adapter • Drives • Memory modules (minimum requirement = two 256 MB DIMMs) ✏ NOTE Minimum operating requirements are: a. System board b. One microprocessor c. Memory (with a minimum of two 256 MB DIMMs) d. A functioning SBCE 6. Install and turn on the blade server. If the problem remains, suspect the following FRUs in the order listed: • DIMM • System board • Microprocessor 100 SBXL52: Hardware Maintenance Manual and Troubleshooting Guide

SBXL52: Hardware Maintenance Manual and Troubleshooting Guide
Undetermined problems
NOTE
When troubleshooting a problem with the blade server, it must be determined whether the
problem is a blade server problem or a problem with the SBCE unit.
•
If the SBCE unit contains more than one blade server and only one of the blade servers
exhibits the problem, it is likely that it is a blade server problem.
•
If all of the blade servers exhibit the same symptom, it is probably a SBCE unit problem;
for more information, see the Intel Server System SBCE
Hardware Maintenance Manual
.
Use the information in this section if the diagnostic tests did not identify the failure, the devices list
is incorrect, or the system is inoperative.
Notes:
1.
Damaged data in CMOS can cause undetermined problems.
To reset the CMOS, remove the
battery for 15 minutes, and then reinstall the battery.
2.
Damaged data in BIOS code can cause undetermined problems.
•
Flash the system with the latest BIOS code.
•
If the system appears inoperative, recover the BIOS (see “Recovering the BIOS code” on
page 25).
Check the LEDs on all the power supplies of the SBCE unit where the blade server is installed. If the
LEDs indicate the power supplies are working correctly, and reseating the blade server does not
correct the problem, complete the following steps:
1.
Check that the front panel is connected to the system board.
2.
If no LEDs on the front panel are working, replace the front panel; then, try to power up the
blade server from the SBCE web interface (see the SBCE documentation for more information).
3.
Turn off the blade server.
4.
Remove the blade server and remove the cover.
5.
Remove or disconnect the following devices (one at a time) until you find the failure (reinstall,
turn on and reconfigure the blade server each time):
•
I/O adapter
•
Drives
•
Memory modules (minimum requirement = two 256 MB DIMMs)
NOTE
Minimum operating requirements are:
a.
System board
b.
One microprocessor
c.
Memory (with a minimum of two 256 MB DIMMs)
d.
A functioning SBCE
6.
Install and turn on the blade server. If the problem remains, suspect the following FRUs in the
order listed:
•
DIMM
•
System board
•
Microprocessor
