1.4.2 Enclosures and Onboard Administrators
HP Server Blade c7000 Enclosure The HP Server Blade c7000 Enclosure is the enclosure model
supported for use in an HP XC hardware configuration. An enclosure is a chassis that houses
and connects blade hardware components. It can house a maximum of 16 half-height or 8
full-height server blades and contains a maximum of 6 power supplies and 10 fans.
The following are general guidelines for configuring enclosures:
• Up to four enclosures can be mounted in a 42U rack.
• If an enclosure is not fully populated with fans and power supplies, see the positioning
guidelines in the HP Server Blade c7000 Enclosure documentation.
• Enclosures are cabled together using their uplink and downlink ports.
• The top uplink port in each rack is used as a service port to attach a laptop or other device
for initial configuration or subsequent debugging .
The following enclosure setup guidelines are specific to HP XC:
• On every enclosure, an Ethernet interconnect module (either a switch or pass-thru module)
is installed in bay 1 for the administration network.
• Hardware configurations that use GigabitEthernet as theinterconnect require anadditional
Ethernet interconnect module (either a switch or pass-thru module) to be installed in bay 2
for the interconnect network.
• Systems that use InfiniBand as the interconnect require a double-wide InfiniBand interconnect
switch module installed in double-wide bay 5 and 6.
• Some systems might need an additional Ethernet interconnect module to support server
blades that require external connections. For more information about external connections,
see “Cabling for the External Network” (page 19).
HP BladeSystem c-Class Onboard Administrator The Onboard Administrator is the management
device for an enclosure, and at least one Onboard Administrator is installed in every enclosure.
You can access the Onboard Administrator through a graphical Web-based user interface, a
command-line interface, or the simple object access protocol (SOAP) to configure and monitor
the enclosure. You can add a second Onboard Administrator to provide redundancy.
Insight Display The Insight Display is a small LCD panel on the front of an enclosure that
provides instant access to important information about the enclosure such as the IP address and
color-coded status. You can use the Insight Display panel to make some basic enclosure settings.
For more information about enclosures and their related components, see the HP Server Blade
c7000 Enclosure Setup and Installation Guide .
1.4.3 iLO2 Console Management Device
Each HP ProLiant server blade has a built-in Integrated Lights Out (iLO2) device that provides
full remote power control and serial console access. You can access the iLO2 device through the
