HP BladeSystem Onboard Administrator

BladeSystem Onboard Administrator (OA) (figure 7) is located below the interconnect bays and

provides component management in c-Class enclosures by:

• Detecting component insertion and removal

• Identifying components and required connectivity

• Managing power and cooling

• Controlling components

Administrators access the BladeSystem OA in several ways:

• Remotely through the web browser graphical user interface (GUI)

• Scriptable command line interface (CLI)

• On-site through the built-in Insight Display diagnostic LCD panel on the front of the enclosure

• OA with KVM (Keyboard, Video, Mouse) module allows direct connection to the enclosure with a

keyboard, video monitor, mouse or KVM switch through a VGA port

When a component is inserted into a bay, the BladeSystem Onboard Administrator immediately

recognizes and identifies the component through presence signals on each bay. If a component is

removed from a bay, the BladeSystem Onboard Administrator deletes the information about that

component from its current configuration.

Each Onboard Administrator module has one Ethernet and one serial port that can be used to link

enclosures in a rack. Enclosure links are designed to support only c-Class enclosures in the same rack,

and both c3000 and c7000 enclosures can be linked and managed together. It is a best practice
