Troubleshooting Boot Failure on Cisco UCS C-Series Rack-Mount Server

ACDF.

When a Cisco UCS C-Series Rack-Mount Server does not boot after installation or replacement, there are a few things that need to be verified to identify the issue. The following four options should be checked:

A. Verify the power source to the equipment: Ensure that the server is properly connected to a power source, and the power source is providing the required power. Check if the power cable is connected correctly, and the power outlet is functioning correctly.

D. Verify that power supplies are receiving power: Check the power supply units (PSUs) for the server and ensure they are receiving power. If the PSUs are not receiving power, it may be a power supply issue.

F. Check the CPU sockets for bent pins: Inspect the CPU sockets for any bent pins, which can prevent the server from booting. Bent pins can be caused by mishandling during installation or replacement of components.

G. Check the Cisco IMC for fan faults: Cisco Integrated Management Controller (IMC) can monitor system components such as fans, temperature sensors, and power supplies. Verify that the IMC is not reporting any fan faults, which can cause the system to shut down or not boot.

The following options are not relevant for this issue:

B. Check for loose HDD cables: This option is not relevant because it is related to the hard disk drive cables, which would not prevent the server from booting.

C. Reseat the DIMMs, CPU, and PCI cards: This option is a good practice during installation, but it is not relevant for an issue where the server is not booting.

E. Reseat the mezzanine card connector: This option is related to the mezzanine card and is not relevant to this issue, as the server is not booting.

In summary, when a Cisco UCS C-Series Rack-Mount Server does not boot after installation or replacement, the power source, power supplies, CPU sockets, and Cisco IMC should be checked to identify the issue.
