NC51xx PCIe 10 Gigabit Server Adapter Software and Configuration Guide

Installation and configuration 21
Configuring multiple NC510x PCIe 10 GbE
adapters
Multiple NC510x PCIe 10 GbE stand up adapters can be configured in a single system.
• Requirements—HP recommends installing 2 GB of system memory per 10 GbE port. Each NC510x
PCIe 10 GbE adapter installed must have a unique IP address assigned.
NOTE: Windows 32 bit may require the Physical Address Extension (PAE) option to utilize 4
GB or more of memory. PAE is a memory address extension that enables support of greater
than 4 GB of physical memory for most 32-bit (IA-32) Intel Pentium Pro and later platforms. For
more information, see PAE Memory and Windows information on the Microsoft
(http://www.microsoft.com
) website.
• Installing—Install additional NC510x PCIe 10 GbE stand up adapters in any empty PCI Express slot
on the system. In a Windows or Linux operating system, when the NC510x driver is installed, the
driver automatically loads for any additional NC510x adapters that are added.
• Enabling—Each adapter can be enabled independently. The user assigns an IP address to each
adapter in the system.
• Disabling—Each adapter can be disabled independently.
Configuring multiple ports on 10GbE adapters
HP multiple port adapters—such as the NC512m Dual Port 10 GbE Multifunction BL-c Adapter—have
multiple ports on a single card.
• Requirements: Each port requires a separate IP address, and each port should be on a separate
subnet for proper network stack functioning.
• Installing: If the driver is installed, it is automatically loaded for each port.
• Enabling: Each port appears as a separate device. Ports can be enabled individually without
interfering with the other ports.
• Disabling: Ports can be disabled individually without interfering with other enabled ports.
Please note that multiple HP NC512m Dual Port 10 GbE Multifunction BL-c Adapters are NOT supported
in a single system.
Boot options
Pre-boot Execution Environment (PXE) allows a server to boot from a remote system using the NC51xx 10
Gigabit Ethernet interface. Through the PXE interface, the server's operating system image is downloaded
from a configured boot server.
PXE boot process requirements
The PXE boot process has the following requirements.
• An HP NC51xx network adapter enabled to support PXE boot.
