•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.

•A Dynamic Host Configuration Protocol (DHCP) server — Used to assign an IP address to the network adapter and to specify a boot image to download and load. Typically, a system administrator configures a DHCP server to provide boot parameters.

•A Trivial File Transfer Protocol (TFTP) server — Used by the network adapter to download a PXE boot loader.

•System BIOS enabled for PCI Expansion ROM scanning of the PCI slot where the network adapter is installed. PCI Expansion ROM scanning allows the network adapter's PXE driver to be loaded and executed during system boot time.

Configuring PCI behavior is system BIOS dependent but usually requires accessing the BIOS setup screen and configuring the PCI advanced or boot properties. Also, the system BIOS must be enabled to boot from the NC51xx network adapter.

•Desired boot order selected to insure that the appropriate boot sequence occurs.

When PCI Expansion ROM scanning is enabled and the NC51xx network adapter is installed correctly, the NC51xx network adapter displays as a boot option in the system BIOS boot order menu.

PXE functionality in the firmware is disabled by default.

Complete the following steps to enable or disable PXE functionality for Windows.

1.Execute the following command to enable PXE functionality: nxflash -i NX_NIC<Device #> --opt-rom-on
