Front view

The following illustration shows the controls, LEDs, and connectors on the front of the solution.

Note

  • The 6U enclosure supports up to six trays.

  • Each tray contains two nodes; one left node and one right node (when viewed from front of enclosure).

  • SD650 V3 tray contains two compute nodes.

Attention

Shared I/O configuration requires specific power on and power off sequence for the two nodes, see below:

  • Power on sequence: first, power on the node with main adapter (right node); then, power on the node with auxiliary adapter (left node).

  • Power off sequence: first, power off the node with auxiliary adapter (left node); then, power off the node with main adapter (right node).

1 Compute node / Left node (odd bay numbers)

6 Front operator panel LEDs. See Front LEDs for more information.

2 Compute node / Right node (even bay numbers)

7 Node power button with LED. See Front LEDs for more information.
3 KVM breakout cable connector

The KVM breakout cable includes VGA connector, serial port connector, and USB 3.0 (5 Gbps) / 2.0 connector. XCC mobile management is supported by USB 2.0 connector on the KVM breakout cable only.

For more information, see KVM breakout cable.

4 1 Gb RJ45 Ethernet port with share-NIC feature for Lenovo XClarity Controller. See Front LEDs for more information.

Lenovo XClarity Controller connection is mutually exclusive between RJ45 Ethernet connector and 25Gb SFP28 Port 1.

9 25 Gb SFP28 Ethernet port (Port 2). See Front LEDs for more information.
5 NMI button.

Press this button to force a nonmaskable interrupt to the processor. You might have to use a pen or the end of a straightened paper clip to press the button. You can also use it to force a blue-screen memory dump. Use this button only when you are directed to do so by Lenovo Support.

10 25 Gb SFP28 Ethernet port (Port 1) with share-NIC feature for Lenovo XClarity Controller. See Front LEDs for more information.
