Controlling Components - HP Xw460c - ProLiant - Blade Workstation Overview

Controlling components

The BladeSystem Onboard Administrator uses embedded management interfaces to provide detailed
information and health status for all bays in the enclosure (Figure 4). The BladeSystem Onboard
Administrator also reports firmware versions for most components in the enclosure and can be used to
update those components.

in an HP BladeSystem c7000 Enclosure
c7000 internal management interfaces
The BladeSystem Onboard Administrator monitors and communicates with several hardware
interfaces to each bay in the c7000 enclosure. The management hardware interfaces include unique
presence pins, Inter-Integrated Circuit (I2C), serial, and Ethernet connections. These management
interface connections are completely isolated from the server blade connections to interconnect
modules.
c7000 external management interfaces
Each c7000 enclosure has several external management interfaces connected to the BladeSystem
Onboard Administrator as shown in Figure 4. The primary external management interface is the
management port for each BladeSystem Onboard Administrator, which is an RJ-45 jack providing
Ethernet communications not only to each BladeSystem Onboard Administrator, but also to every
device or interconnect bay with a management processor. This includes ProLiant Onboard
Administrator (iLO 2) communication for the server blades and any interconnect module using the
c-Class embedded Ethernet management network, such as Virtual Connect Manager. For redundant
BladeSystem Onboard Administrators, both BladeSystem Onboard Administrator management ports
