interconnect group associated with the enclosure group. This ensures that all enclosures in the
enclosure group are configured with the same network connectivity.
•
The appliance automatically names the logical interconnect when you add the enclosure. The
naming convention for logical interconnects follows:
enclosure_name-LI
Where enclosure_name is the name of the enclosure.
Deleting a logical interconnect
To delete a logical interconnect, you must remove the enclosure from management.
19.2.3.4 About the HP Virtual Connect FlexFabric–20/40 F8 interconnect module
The HP Virtual Connect FlexFabric–20/40 F8 Module for HP BladeSystem c-Class has several
unique features:
•
Four dedicated 40G QSFP+ ports with support for 1x40G mode, 4x10G modes, or 1x10G
mode. When a QSFP+ port is configured for 4x10G operation, a pluggable module with an
attached splitter cable must be installed to multiplex the QSFP+ port into four SFP+ ports on
the remote end. The four Ethernet QSFP ports are identified as Q1–Q4. The multiplex Ethernet
ports are identified as Qx.1–Qx.4.
•
Eight dedicated 10G ports identified as X1–X8. These ports support Ethernet and Fibre Channel
traffic. Port pairs X5/X6 and X7/X8 carry one type of network traffic, either Ethernet or Fibre
Channel. Ports X9 and X10 are internal stacking ports.

CAUTION:
To avoid overheating:
•
Make sure there are 10 fans in the enclosure.
•
Do not insert more than six HP Virtual Connect FlexFabric–20/40 F8 modules in one enclosure.
19.2.4 About logical interconnect groups
A logical interconnect group is associated with an enclosure group and is used to define the logical
interconnect configuration for every enclosure that is added to that enclosure group. Logical
interconnect configurations include the I/O bay occupancy, stacking mode, uplink ports and uplink
sets, available networks, and downlinks.
The logical interconnect group reserves the appropriate interconnect ports for stacking links required
for the stacking mode. For the enclosure stacking mode:
•
All interconnects in an enclosure are members of the logical interconnect.
•
Horizontally adjacent interconnects must be the same interconnect type.
•
Horizontally adjacent interconnects reserve one port per enclosure for internal stacking links,
called East-West links.
•
Vertically adjacent interconnects reserve an additional port per enclosure for external stacking
links, called North-South links.
The uplink sets portion of the logical interconnect group defines the initial configuration for uplink
sets for each enclosure added to the enclosure group. You can change the uplink sets for a logical
interconnect, and existing enclosures are not affected by changes you make to uplink sets in the
logical interconnect group. If you change the uplink sets for an existing logical interconnect group,
