Population rules for mezzanine cards in the BX400 S1 system unit
The connection blade slots of the BX400 S1 system unit are numbered as
follows.
Figure 34: Connection blade slots (BX400 S1 system unit)
The table below shows the connections of the connection blade slots to the slots
for mezzanine cards.

Connection blades within one fabric must have the same technology, i.e.
either Ethernet or Fibre Channel or Infiniband.
As a result, the rules for populating the mezzanine card slots are as follows:
●
If a 1 Gb Ethernet mezzanine card is installed in slot 1 of a server blade, at
least one 1 Gb Ethernet connection blade must be installed in CB slot 2 of
the system unit.
●
If a 10 Gb Ethernet mezzanine card or a 10Gb CNA mezzanine card is
installed in slot 1 of a server blade, at least one 10 Gb Ethernet connection
blade must be installed in CB slot 2 of the system unit.
