Hot-plug components
I The two connection blades within a fabric must have the same
technology, i.e. either Ethernet or Fibre Channel or Infiniband.
When filling the slots in fabrics 2, 3 and 4, also make sure the server blades are
fitted with the appropriate mezzanine cards. The following rules apply for fitting
the mezzanine card slots of the server blades:
● 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 fabric 2 of the
system unit.
● If a 10 Gb Ethernet mezzanine card is installed in slot 1 of a server blade, at
least one 10 Gb Ethernet connection blade must be installed in fabric 2 of
the system unit.
● If an FC mezzanine card is installed in slot 1, at least one FC connection
blade must be installed in fabric 2.
● If an Infiniband mezzanine card is installed in slot 1, an Infiniband connection
blade must be installed in fabric 2.
I In this case, only one of two channels of the Infiniband mezzanine
card is used.
● If a 1 Gb Ethernet mezzanine card is installed in slot 2 of a server blade, at
least one 1 Gb Ethernet connection blade must be installed in fabric 3 or in
fabric 4 of the system unit.
● If a 10 Gb Ethernet mezzanine card is installed in slot 2 of a server blade, at
least one 1 Gb Ethernet connection blade must be installed in fabric 3 of the
system unit.
● If an FC mezzanine card is installed in slot 2, at least one FC connection
blade must be installed in fabric 3.
● If an Infiniband mezzanine card is installed in slot 2, Infiniband connection
blades should be installed in fabrics 3 and 4.
I In this case, both channels of the Infiniband mezzanine card are
used.
● You can install a combination of FC, Ethernet and Infiniband mezzanine
cards in a server blade. In this case, the Ethernet mezzanine card should be
installed in slot 1 and the FC or Infiniband mezzanine card in slot 2 of the
server blade.
