Specific HP XC Setup Guidelines

The following enclosure setup guidelines are specific to HP XC:

•On every enclosure, an Ethernet interconnect module (either a switch or pass-through module) is installed in interconnect bay #1 (see callout 1 in Figure 1-9) for the administration network.

•Hardware configurations that use Gigabit Ethernet as the interconnect can share with the administration network in interconnect bay #1.

•Systems that use InfiniBand as the interconnect require a double-wide InfiniBand interconnect switch module installed in interconnect bays #3 and #4 (see callouts 6 and 7 in Figure 1-9).

•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 41).

1.2.3HP 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.
