Solving undetermined problems

If the diagnostic tests did not diagnose the failure or if the server is inoperative, use the information in this section.

If you suspect that a software problem is causing failures (continuous or intermittent), see “Software problems” on page 23.

Damaged data in CMOS memory or damaged firmware can cause undetermined problems. To reset the CMOS data, use the password switch 2 (SW4) to override the power-on password and clear the CMOS memory; see “Locating parts on the system board” on page 32.

Check the LEDs on all the power supplies. If the LEDs indicate that the power supplies are working correctly, do the following:

1.Turn off the server.

2.Make sure that the server is cabled correctly.

3.Remove or disconnect the following devices, one at a time, until you find the failure. Turn on the server and reconfigure it each time.

v Any external devices

vSurge-suppressor device (on the server)

vModem, printer, mouse, and non-Lenovo devices

vEach adapter

vHard disk drives

vMemory modules:

The minimum configuration requirement is 1 GB DIMM per microprocessor (2 GB in a two-microprocessor configuration).

The following minimum configuration is required for the server to start:

vOne microprocessor

vOne 1 GB DIMM

vOne power supply

vPower cord

vServeRAID SAS adapter

vSystem board assembly

4.Turn on the server. If the problem remains, suspect the following components in the following order:

a.Power supply

b.Power-supply cage

c.Memory

d.Microprocessor

e.System board

If the problem is solved when you remove an adapter from the server but the problem recurs when you reinstall the same adapter, suspect the adapter; if the problem recurs when you replace the adapter with a different one, suspect the system board or extender card.

If you suspect a networking problem and the server passes all the system tests, suspect a network cabling problem that is external to the server.

Event logs

Error codes and messages are displayed in the following types of event logs:

vPOST event log: This log contains the three most recent error codes and messages that were generated during the POST.

Equipped with up to 512GB of DDR3 memory, the RD240 ensures high memory bandwidth and reduced latency, improving overall system responsiveness.

In terms of storage, the RD240 supports a versatile range of options, with configurations allowing for up to twelve 3.5-inch hard drives or a combination of SSDs and HDDs. This flexibility enables businesses to tailor their storage solutions based on performance and capacity needs. Additionally, the server includes integrated RAID options, which enhance data protection and availability.

On the other hand, the RD230 is a compact 1U rack server that prioritizes space efficiency without compromising on performance. Like its larger counterpart, the RD230 supports dual Intel Xeon processors, but its design focuses on providing a more streamlined solution for environments with limited rack space. With support for up to 128GB of RAM, the RD230 can efficiently handle various applications, from web hosting to application serving.

Both servers are equipped with advanced management tools, such as the Lenovo XClarity Controller, which simplifies system monitoring and maintenance. This allows IT administrators to deploy updates, monitor hardware health, and manage resources with ease, leading to minimized downtime and optimized performance.

Furthermore, Lenovo places a strong emphasis on energy efficiency, ensuring that both the RD240 and RD230 have features like power management and cooling technologies. These innovations reduce their carbon footprint while lowering operating expenses, making them attractive choices for environmentally-conscious businesses.

In summary, the Lenovo RD240 and RD230 servers offer a blend of performance, flexibility, and efficient management, catering to the diverse needs of modern enterprises. With their robust features and reliable characteristics, they stand as dependable solutions for businesses looking to enhance their IT infrastructure while supporting future scalability.
