interconnect module management processors such as the HP Virtual Connect Manager. Integrating all
these management capabilities provides powerful hardware management for remote administration,
local diagnostics, and troubleshooting.
Onboard Administrator
The heart of the c-Class enclosure management is the Onboard Administrator. The Onboard
Administrator module in the c7000 enclosure provides four services for the entire enclosure: detection,
identification, management, and control. An optional second Onboard Administrator in the c7000
enclosure provides complete redundancy for these services. There are three ways to access the
Onboard Administrator: web browser graphical user interface (GUI), scriptable command line
interface (CLI), and the built-in Insight Display diagnostic LCD panel included in the front of every
c-Class enclosure.
Managing a c-Class enclosure involves multiple functions:
• detecting component insertion and removal
• identifying components including required connectivity
• managing power and cooling
• controlling components including remote control and remote consoles
Detecting component insertion and removal
Onboard Administrator provides component control in c-Class enclosures. Component management
begins after the component is detected and identified. The Onboard Administrator detects
components in BladeSystem c-Class enclosures through presence signals on each bay. When a
component is inserted into a bay, the Onboard Administrator immediately recognizes and identifies
the component. If a component is removed from a bay, the Onboard Administrator deletes the
information about that component.
Identifying components
To identify a component, the Onboard Administrator reads a Field-Replaceable Unit (FRU) Electrically
Erasable Programmable Read-Only Memory (EEPROM) that contains specific factory information
about the component such as product name, part number, and serial number. All FRU EEPROMs in
c-Class enclosures are always powered, even if the component is turned off, so the Onboard
Administrator can identify the component prior to granting power. For devices such as fans, power
supplies, and Insight Display, the Onboard Administrator reads the FRU EEPROMs directly. The
Onboard Administrator accesses server blade FRU EEPROMs through their iLO 2 management
processors.
The server blades contain several FRU EEPROMs: one on the server board which contains server
information and embedded NIC information and one on each of the installed mezzanine option
cards. Server blade control options include auto login to the iLO 2 web interface and remote server
consoles, virtual power control, and boot order control. Server blade control options also include
extensive server hardware information including BIOS and iLO 2 firmware versions, server name, NIC
and option card port IDs, and port mapping. The Onboard Administrator provides easy-to-understand
port mapping information for each of the server blades and interconnect modules in the enclosure.
The NIC and mezzanine option FRU information informs the Onboard Administrator of the type of
interconnects each server requires. Before granting power to a server blade, the Onboard
Administrator compares this information with the FRU EEPROMs on installed interconnect modules to
check for electronic keying errors. For interconnect modules, the Onboard Administrator provides
virtual power control, dedicated serial consoles, and management Ethernet connections, based on
which specific interconnect features are included.
