2 Power supply 1

3 Power supply 2 (available on some models)

The hot-swap redundant power supplies help you avoid significant interruption to the operation of the system when a power supply fails. You can purchase a power supply option from Lenovo and install the power supply to provide power redundancy without turning off the server.

On each power supply, there are three status LEDs near the power cord connector. For information about the LEDs, see Rear view LEDs.

4 NMI button

Press this button to force a nonmaskable interrupt (NMI) to the processor. By this way, you can blue screen the server and take a memory dump. You might have to use a pen or the end of a straightened paper clip to press the button.

5 USB 3.0 connectors (2)

Attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.

6 VGA connector

Used to attach a high-performance monitor, a direct-drive monitor, or other devices that use a VGA connector.

7 1 Gb Ethernet connector 2

8 1 Gb Ethernet connector 1

Used to attach an Ethernet cable for a LAN. Each Ethernet connector has two status LEDs to help you identify the Ethernet connectivity and activity. For information about the LEDs, see Rear view LEDs.

Ethernet connector 1 can be set as XClarity Controller network connector. To set Ethernet connector 1 as XClarity Controller network connector, start Setup utility, go to BMC Settings > Network Settings > Network Interface Port and select Shared. Then, go to Shared NIC on and select Onboard Port 1.

9 XClarity Controller network connector

Used to attach an Ethernet cable to manage the system using XClarity Controller.

10 Ethernet connector 2 on the LOM adapter

11 Ethernet connector 1 on the LOM adapter

The LOM adapter provides two extra Ethernet connectors for network connections.

Ethernet connector 1 on the LOM adapter can be set as XClarity Controller network connector. To set the Ethernet connector 1 as XClarity Controller network connector, start Setup utility, go to BMC Settings > Network Settings > Network Interface Port and select Shared. Then, go to Shared NIC on and select PHY Card.
