Figure 7. OCP 3.0 Ethernet adapter (two connectors, seen
from the rear)
Figure 8. OCP 3.0 Ethernet adapter (four connectors, seen

The OCP 3.0 Ethernet adapter provides two or four extra Ethernet connectors for network connections.
By default, Ethernet connector 1 (the first port starting from the left in the rear server view) on the OCP 3.0

the shared management connector fails, traffic can automatically switch over to another connector on the
adapter.
Hot-swap drives and drive bays
The drive bays on the front and rear of your server are designed for hot-swap drives. The number of the
installed drives in your server varies by model. 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. Vacant drive
bays must be occupied by drive fillers.
NMI button
Press this button to force a nonmaskable interrupt (NMI) to the processor. By this way, you can make the
operating system halt (such as Windows Blue Screen of Death) and take a memory dump. You might have to
use a pen or the end of a straightened paper clip to press the button.
