HP Virtual Connect for c-Class BladeSystem Version 3.00 Setup and Installation Guide for HP Integrity BL8x0c i2 Series Server Blades

Installation 39
• VC-FC 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.
• Install the VC-FC modules in interconnect bays 3 or higher. Interconnect bays 1 and 2 are reserved
for Ethernet modules.
• 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.
• Do not mix Virtual Connect 8Gb 24-port FC modules with Virtual Connect 4Gb or 8Gb 20-port FC
modules in the horizontally adjacent interconnect bays connected to the same server blade
mezzanine card.
NOTE: Virtual Connect assigns and migrates MAC addresses and/or WWNs for ports
connected to Virtual Connect Ethernet modules or Virtual Connect Fibre Channel modules
only.
For more information on the association between the server blade mezzanine connectors and the
interconnect bays, see the HP BladeSystem enclosure setup and installation guide that ships with the
enclosure. During server blade installation, the location of the mezzanine card determines the installation
location of the interconnect modules.
For specific interconnect module port connection information for each blade, see the HP BladeSystem
enclosure setup and installation guide that ships with the enclosure. Connections differ by server blade
type.
HP Virtual Connect Flex-10 Module guidelines
The following guidelines apply to the installation or replacement of HP Virtual Connect Flex-10 10Gb
Ethernet Modules:
• Only install HP Virtual Connect Flex-10 Modules into bays horizontally adjacent to bays containing
HP Virtual Connect Flex-10 Modules.
If any other type of module is installed, the second one discovered is set to UNKNOWN and no
connections are made to the server NICs attached to the interconnect bay. The module is set to
UNKNOWN because it will be removed automatically from the VC domain when removed
physically from the interconnect bay.
• If an HP Virtual Connect Flex-10 Module is connected to a Flex-10 NIC that corresponds to an
Ethernet connection in a server profile, then replacing the module with any other type of Virtual
Connect Ethernet module requires that it be removed administratively before replacement. For more
information on administrative module removal, see the HP Virtual Connect for c-Class BladeSystem
User Guide.
If the replacement module is not removed administratively, the module is marked as INCOMPATIBLE
and no connections are made to the server NICs attached to the interconnect bay.
• An empty interconnect bay horizontally adjacent to a bay containing an HP Virtual Connect Flex-10
Module is treated as if it has a Flex-10-compatible Ethernet module for server configuration. If the
corresponding server NIC is Flex-10, it is partitioned according to the connections in the server
profile. Adding a module that does not support Flex-10 when the corresponding server is configured
for Flex-10 results in the module being set to INCOMPATIBLE.
