1 USB 2.0 connector with XClarity Controller management

Depending on the setting, this connector supports USB 2.0 function, XClarity Controller management function, or both.

  • If the connector is set for USB 2.0 function, you can attach a device that requires a USB 2.0 connection, such as a keyboard, a mouse, or a USB storage device.

  • If the connector is set for XClarity Controller management function, you can attach a mobile device installed with the application to run XClarity Controller event logs.

  • If the connector is set to have both functions, you can press the system ID button for three seconds to switch between the two functions.

2 USB 3.2 Gen 1 connector (5Gbps)

Used to attach a device that requires a USB 2.0 or 3.2 connection, such as a keyboard, a mouse, or a USB storage device.

3 Power button with power status LED

You can press the power button to turn on the server when you finish setting up the server. You also can hold the power button for several seconds to turn off the server if you cannot turn off the server from the operating system. The power status LED helps you determine the current power status.
StatusColorDescription
Solid onGreenThe server is on and running.
Slow blinking (about one flash per second)GreenThe server is off and is ready to be powered on (standby state).
Fast blinking (about four flashes per second)GreenThe server is off, but the XClarity Controller is initializing, and the server is not ready to be powered on.
OffNoneThere is no ac power applied to the server.

4 Network activity LED

When an OCP 3.0 Ethernet adapter is installed, the network activity LED on the front I/O assembly helps you identify the network connectivity and activity.

StatusColorDescription
OnGreenThe server is connected to a network.
BlinkingGreenThe network is connected and active.
OffNoneThe server is disconnected from the network.
Note
If no OCP 3.0 Ethernet adapter is installed, this LED is off.

5 System ID button with system ID LED

Use this system ID button and the blue system ID LED to visually locate the server. A system ID LED is also located on the rear of the server. Each time you press the system ID button, the state of both the system ID LEDs changes. The LEDs can be changed to on, blinking, or off.

If the XClarity Controller USB connector is set to have both the USB 2.0 function and XClarity Controller management function, you can press the system ID button for three seconds to switch between the two functions.

6 System error LED

The system error LED provides basic diagnostic functions for your server. If the system error LED is lit, one or more LEDs elsewhere in the server might also be lit to direct you to the source of the error.

StatusColorDescriptionAction
OnYellowAn error has been detected on the server. Causes might include but are not limited to the following errors:

  • A fan failure

  • A memory error

  • A storage failure

  • A PCIe device failure

  • A power supply failure

  • A CPU error

  • A system board error

Check the event log to determine the exact cause of the error.

Alternatively, follow the light path diagnostics to determine if additional LEDs are lit that will direct you to identify the cause of the error.

OffNoneThe server is off or the server is on and is working correctly.None.
