This section lists Sun Fire X4540-supported FRUs/CRUs compatibility with the supported BIOS versions and other FRUs/CRUs.
The following table lists System Controllers supported by the Sun Fire X4540 server and their compatibility with supported CPUs, BIOS versions and HyperTransport 3.0.
The following table shows FRUs and CRUs supported by the Sun Fire X4500 and X4540 servers and their compatibility with other FRUs/CRUs.
| Note - The chassis FRUs are for replacing failed chassis or backplanes, and not for upgrading the chassis. |
The third power supply is not supported in x4500 systems and is only supported in X4540 systems originally manufactured with either of the following CPUs:
Three PSUs are fully redundant at 110 VAC and provides resiliency against a power supply failure. If one power supply fails, the remaining two power supplies will continue to operate the system. Two PSUs does not provide power redundancy and is not supported.
To order the third PSU, you must first determine that the x4540 system is compatible with a third power supply (see conditions above), then order the following parts:
| Note - The third power supply is not supported in an older X4540 (#541-1218) or the Sun Fire X4500 system. |
| Note - When a system is configured for 3 PSUs at 100-120V AC and only 2 PSUs are installed, the amber System Fault LED LED illuminates. |
For power supply part numbers, see Replacing a Power Supply (CRU).
The following 2356 CPUs are supported by the X4540:
