System diagnostics
This chapter helps you identify and solve problems that might occur while you are using the system.
For any issue, first ensure you are using the latest firmware and files. Firmware upgrades include updates for
BIOS, the baseboard management controller (BMC), and the hot-swap controller (HSC). In addition to the
server firmware and files, also update any drivers used for components you have installed in your system,
such as video drivers, network drivers, and SCSI drivers.
