HP BladeSystem c-Class Advanced management iLO 2 is a standard component of ProLiant c-Class server blades that provides server health and remote server blade manageability. Its features are accessed from a network client device using a supported web browser. In addition to other features, iLO 2 provides remote keyboard, mouse, and video (text and graphics) capability for a server blade, regardless of the state of the host OS or host server blade. iLO 2 includes an intelligent microprocessor, secure memory, and a dedicated network interface. This design makes iLO 2 independent of the host server blade and its OS. iLO 2 provides remote access to any authorized network client, sends alerts, and provides other server blade management functions. Using a supported web browser, you can: • Remotely access the console of the host server blade, including all text mode and graphics mode screens with full keyboard and mouse controls. • Remotely power up, power down, or reboot the host server blade. • Remotely boot a host server blade to a virtual media image to perform a ROM upgrade or install an OS. • Send alerts from iLO 2 regardless of the state of the host server blade. • Access advanced troubleshooting features provided by iLO 2. • Launch a web browser, use SNMP alerting, and diagnose the server blade with HP SIM. • Configure static IP bay settings for the dedicated iLO 2 management NICs on each server blade in an enclosure for faster deployment. To connect to the server blade using iLO 2, install the server blade in an enclosure. Onboard Administrator assigns an IP address to enable iLO 2 connectivity to the server blade. The c-Class tab enables you to control specific settings for the HP BladeSystem. iLO 2 also provides webbased status for the HP BladeSystem configuration. For detailed information about iLO 2, refer to the HP Integrated Lights-Out User Guide on the HP website (http://www.hp.com/servers/lights-out). Network-based PXE deployment PXE is a component of the Intel® WfM specification. The PXE model enables server blades to load and execute an NBP from a PXE server and to execute a pre-configured image. The image can be an OS image created by software utilities or a boot diskette image. This feature enables a user to configure a server blade and install an OS over a network. Deployment overview When a PXE-enabled target server blade boots, it obtains an IP address from a DHCP server. The target server blade obtains the name of the NBP from the appropriate boot server. Then, the target server blade uses TFTP to download the NBP from the boot server and executes the image. IMPORTANT: To connect to a network with a Pass-Thru module, always connect the Pass-Thru module to a network device that supports Gigabit speed. For each server blade being deployed, the PXE server must be connected to the NIC designated for PXE. The server blade defaults PXE functions to NIC 1, but any of the NC series NICs in the server blade can Software and configuration utilities 43
