1 Mini DisplayPort connector​

The Mini DisplayPort (MiniDP) connector can be used to attach a high-performance monitor and a direct-drive monitor with a video converter, or the devices that use a MiniDP connector.

2 USB 3.1 Gen 1 (5 Gbps) connector​

The USB 3.1 Gen 1 (5 Gbps) connector can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.

3 USB 3.2 Gen 1 (5 Gbps) with connector USB2.0 XCC management​

The connector can function as a regular USB 3.2 Gen 1 connector to the host OS; it can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.

In addition, the connector can function as a USB 2.0 Lenovo XClarity Controller management port.

4 5 E3.S drive LEDs​

Each E3.S drive comes with an activity LED and a status LED.

LEDStatusDescription
1 Drive status LED (yellow)Solid onThe drive has an error.
Slow blinking (about one flash per second)The drive is being rebuilt.
Fast blinking (about three flashes per second)The drive is being identified.
2 Drive activity LED (green)Solid onThe drive is powered but not active.
BlinkingThe drive is being accessed (reading or writing data).

6 E3.S drive bays​

The drive bays are used to install E3.S hot-swap drives. When you install drives, follow the order of the drive bay numbers. The EMI integrity and cooling of the server are protected by having all drive bays occupied. The vacant drive bays must be occupied by drive bay fillers or drive fillers.

7 Pull-out information tab​

This tab contains network information such as MAC address and XCC network access label.

8 Power button with LED (green)​

Press this button to turn the server on and off manually. The states of the power LED are as follows:
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)Green
  • The server is off, but the XClarity Controller is initializing, and the server is not ready to be powered on.
  • System-board-assembly power has failed.
OffNonePower is not present, or the power supply has failed.

9 System ID button with LED (blue)​

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. You can also use the Lenovo XClarity Controller or a remote management program to change the state of the system ID LEDs to assist in visually locating the server among other servers.

10 System error LED (yellow)​

The system error LED helps you to determine if there are any system errors.
StatusColorDescriptionAction
OnAmberAn error has been detected on the server. Causes might include but are not limited to the following errors:

  • The temperature of the server reached the non-critical temperature threshold.

  • The voltage of the server reached the non-critical voltage threshold.

  • A fan has been detected to be running at low speed.

  • A hot-swap fan has been removed.

  • The power supply has a critical error.

  • The power supply is not connected to the power.

  • A processor error.

  • A system I/O board or processor board error.

  • Abnormal status is detected on the Processor Neptune® Core Module.

  • Check the Lenovo XClarity Controller event log and the system event log to determine the exact cause of the error.

  • Check if additional LEDs in the server are lit. It will direct you to the error source. See Troubleshooting by system LEDs and diagnostics display.

  • Save the log if necessary.

Note
For server models with Processor Neptune® Core Module installed, it is required to open the top cover to check the LED status of the leakage detection sensor module. For more instructions, see Leakage detection sensor module LED.
OffNoneThe server is off or the server is on and is working correctly.None.

11 Network activity LED (green)​

When an OCP module is installed, the network activity LED on the front I/O assembly helps you identify the network connectivity and activity. If no OCP module is installed, this LED is off.
StatusColorDescription
OnGreenThe server is connected to a network.
BlinkingGreenThe network is connected and active.
OffNoneThe server is disconnected from the network.
Note
If the network activity LED is off when an OCP module is installed, check the network ports in the rear of your server to determine which port is disconnected.

12 External diagnostics connector​

The connector is for connecting an external diagnostics handset. See External diagnostics handset for more details.

13 Rack release latches​

If your server is installed in a rack, you can use the rack latches to help you slide the server out of the rack. You also can use the rack latches and screws to secure the server in the rack so that the server cannot slide out, especially in vibration-prone areas.

14 2.5-inch drive bays​

The drive bays are used to install hot-swap 2.5-inch drives. When you install drives, follow the order of the drive bay numbers. The EMI integrity and cooling of the server are protected by having all drive bays occupied. The vacant drive bays must be occupied by drive bay fillers or drive fillers.
