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 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 web-
based 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
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
