• Lenovo XClarity Controller If you need to install a specific update, you can use the Lenovo XClarity Controller interface for a specific server. Notes: – To perform an in-band update through Windows or Linux, the operating system driver must be installed and the Ethernet-over-USB (sometimes called LAN over USB) interface must be enabled.
Tech Tips Lenovo continually updates the support website with the latest tips and techniques that you can use to solve issues that your server might encounter. These Tech Tips (also called retain tips or service bulletins) provide procedures to work around issues or solve problems related to the operation of your server.
Power off the server The server remains in a standby state when it is connected to a power source, allowing the Lenovo XClarity Controller to respond to remote power-on requests. To remove all power from the server (power status LED off), you must disconnect all power cables.
Use the information in this section to learn about each of the components associated with your server. Identifying your server When you contact Lenovo for help, the machine type, model, and serial number information helps support technicians to identify your server and provide faster service.

An alert is a message or other indication that signals an event or an impending event. Alerts are generated by the Lenovo XClarity Controller or by UEFI in the servers. These alerts are stored in the Lenovo XClarity Controller Event Log. If the server is managed by the Chassis Management Module 2 or by the Lenovo XClarity Administrator, alerts are automatically forwarded to those management applications.

Lenovo XClarity Controller event log The Lenovo XClarity Controller monitors the physical state of the server and its components using sensors that measure internal physical variables such as temperature, power-supply voltages, fan speeds, and component status. The Lenovo XClarity Controller provides various interfaces to systems management software and to system administrators and users to enable remote management and control of a server.
“Viewing Event Logs” section in the XCC documentation compatible with your server at https:// sysmgt.lenovofiles.com/help/topic/lxcc_frontend/lxcc_overview.html The front operator panel and error LEDs The front operator panel is a system of LEDs on various external and internal components of the server that leads you to the failed component.
System ID button/LED (blue): Use this blue LED to visually locate the server among other servers. This LED is also used as a presence detection button. You can use Lenovo XClarity Administrator to light this LED remotely. System-error LED (yellow): When this yellow LED is lit, it indicates that a system error has occurred. A system-error LED is also on the rear of the server.
Table 16. 450 watts Power supply LED Description Power output LED • Green: The server is on and the power supply is working normally. (green) • Blinking green: The power supply is in zero-output mode (standby). When the server power load is low, one of the installed power supplies enters into the standby state while the other one delivers entire load.
• Any external devices. • Surge-suppressor device (on the server). • Printer, mouse, and non-Lenovo devices. • Each adapter. • Hard disk drives. • Memory modules until you reach the minimum configuration that is supported for the server.
1. Check the event log of the application that is managing the server and follow the suggested actions to resolve any event codes. • If you are managing the server from the Lenovo XClarity Administrator, begin with the Lenovo XClarity Administrator event log.
