Installation requirements
CAUTION: Always use blanks to fill empty spaces in enclosures. This arrangement ensures
proper airflow. Using an enclosure without the proper blanks results in improper cooling that can
lead to thermal damage.
Observe the following requirements:
• In all Virtual Connect configurations, a VC-Enet or FlexFabric module must be installed in the enclosure.
The embedded VCM operates on this module.
• VC-Enet modules are used typically in pairs to provide access to all Ethernet controllers on the server
blade.
• The specific interconnect bays with Ethernet connectivity depend on mezzanine card locations within
the server blade.
• For c3000 enclosures, when two Fibre Channel mezzanine cards are installed in slots 2 and 3 of a
full-height server blade, the VC Manager only creates Fibre Channel connections and assigns WWNs
to the ports associated with the Fibre Channel mezzanine card in slot 2. This restriction does not apply
for c7000 enclosures.
• For each Ethernet mezzanine port you want to manage with VCM, install a VC-Enet, HP VC
FlexFabric-20/40 F8 Module, or HP VC FlexFabric 10Gb/24-port Module in the interconnect bay
connected to that port. For more information, see the appropriate HP BladeSystem enclosure setup and
installation guide.
• For Ethernet connections, Virtual Connect can be configured to assign or migrate MAC addresses for
device bay ports connected to VC-Enet or FlexFabric modules.
• For Fibre Channel connections, FlexFabric module SFP ports can be connected only to Fibre Channel
switch ports that support N_port_ID virtualization. To verify that NPIV support is provided, see the
firmware documentation that ships with the Fibre Channel switch.
• When using optional transceiver modules, or when using stacking cables to connect multiple VC-Enet
modules or multiple FlexFabric modules, order the cables and transceiver modules separately. For more
information, see the HP Virtual Connect QuickSpecs on the HP website
(http://www.hp.com/go/vc/manuals).
• All modules in the enclosure require a valid and unique IP address, and all modules must be on the same
subnet. Use a DHCP server or the Onboard Administrator EBIPA feature to assign each module an IP
address.
• For server or I/O interconnect hardware changes that involve adding or removing Flex-10 functionality,
the profile assigned to a server or server bay must be removed, all hardware changes performed, and
the profile reassigned. Otherwise, indeterminate network operation might occur. For more information,
see "Upgrading or removing an HP Virtual Connect Flex-10, HP Virtual Connect FlexFabric, or HP
Virtual Connect Flex-10/10D module (on page 54)."
